What is new material
New materials refer to those materials that have just appeared or are already under development and have excellent properties and special functions that traditional materials do not have. There is no clear boundary between new materials and traditional materials. New materials are developed on the basis of traditional materials.
applications
As the foundation and forerunner of high-tech, new materials have a wide range of applications. Together with information technology and biotechnology, they have become the most important and most promising fields in the 21st century. Like traditional materials, new materials can be classified from many different perspectives such as structural composition, function and application field. Different classifications overlap and nest with each other. At present, new materials are generally divided into the following main fields according to application fields and current research hotspots:
Electronic information materials, new energy materials, nanomaterials, advanced composite materials, advanced ceramic materials, ecological environment materials, new functional materials (including high-temperature superconducting materials, magnetic materials, diamond films, functional polymer materials, etc.), biomedical materials, high-performance structural materials, intelligent materials, new building and chemical materials, etc.

Nanomaterials
Nanomaterials are a general term for zero-dimensional, one-dimensional, two-dimensional, and three-dimensional materials with small size effects, which are composed of ultrafine particles with a size of less than 100nm (0.1-100nm). The concept of nanomaterials was formed in the mid-1980s. Since nanomaterials exhibit unique optical, electrical, magnetic, thermal, mechanical, and mechanical properties, nanotechnology has rapidly penetrated into various fields of materials and has become a hot spot in the current world scientific research. According to physical form, nanomaterials can be roughly divided into five categories: nanopowders, nanofibers, nanofilms, nanoblocks, and nanophase-separated liquids. Although the nanomaterials that have been industrialized are mainly nanopowder materials such as calcium carbonate, white carbon black, and zinc oxide, and others are basically still in the primary research stage of the laboratory, and large-scale application is expected to be 5-10 years later, there is no doubt that nanotechnology represented by nanomaterials will have a profound impact on the economic and social development of the 21st century.
Current research hotspots and technological frontiers include: nano-assembly materials represented by carbon nanotubes; high-performance nanostructured materials such as nano-ceramics and nano-composites; design and synthesis of nano-coating materials; development of nano-electronic devices such as single-electron transistors, nano-lasers and nano-switches; and C60 ultra-high-density information storage materials.
Composite materials can be divided into two categories according to their uses: structural composite materials and functional composite materials. Structural composite materials are mainly used as materials for load-bearing structures. They are composed of reinforcement components (such as glass, ceramics, carbon, polymers, metals, natural fibers, fabrics, whiskers, sheets and particles, etc.) that can bear loads and matrix components (such as resins, metals, ceramics, glass, carbon and cement, etc.) that can connect the reinforcements to form a whole material and transmit force. Structural materials are usually divided into polymer-based composite materials, metal-based composite materials, ceramic-based composite materials, carbon-based composite materials and cement-based composite materials according to the different matrices. Functional materials refer to composite materials that provide other physical, chemical, biological and other properties in addition to mechanical properties. There are many types of composite materials, including piezoelectric, conductive, radar stealth, permanent magnet, photochromic, sound absorption, flame retardant, bio-self-absorption, etc., which have broad development prospects. In the future, the proportion of functional composite materials will exceed that of structural composite materials and become the mainstream of composite material development. The research direction of composite materials in the future will mainly focus on nanocomposites, bionic composite materials, and the development of multifunctional, smart and intelligent composite materials.
Composite materials are materials with two or more phase structures formed by combining two or more materials with different properties through physical and chemical combination. Such materials not only have better performance than any single material in the composition, but also have unique properties that the components alone do not have.

Bio-environmental materials
The characteristics of this type of material are that it consumes less resources and energy, has little pollution to the ecology and environment, has a high recycling rate, and is in harmony with the ecological environment throughout its entire life cycle from material manufacturing, use, disposal to recycling. It mainly includes: environmentally compatible materials, such as pure natural materials (wood, stone, etc.), biomimetic materials (artificial bones, artificial organs, etc.), green packaging materials (green packaging bags, packaging containers), ecological building materials (non-toxic decorative materials, etc.); environmentally degradable materials (biodegradable plastics, etc.); environmental engineering materials, such as environmental restoration materials, environmental purification materials (molecular sieves, ion sieve materials), environmental alternative materials (phosphorus-free laundry detergent additives), etc. The research hotspots and development directions of ecological and environmental materials include the design of recycled polymers (plastics), the theoretical system of material environmental coordination evaluation, and new processes, technologies and methods to reduce the environmental load of materials.
Eco-environmental materials were proposed when humans realized the important strategic significance of ecological environmental protection and countries around the world were embarking on the path of sustainable development. They are an inevitable trend in the development of materials science and engineering research at home and abroad. It is generally believed that ecological environmental materials are materials that have satisfactory performance and are endowed with excellent environmental coordination.
Biomedical materials are a new type of high-tech materials used to diagnose, treat or replace human tissues and organs or enhance their functions. They are a new and developing field in materials science and technology. They not only have high technical content and economic value, but are also closely related to the life and health of patients. In the past 10 years, the market for biomedical materials and products has maintained a growth rate of about 20%.
Biomedical materials are divided into medical metal materials, medical polymer materials, bioceramic materials and biomedical composite materials according to their material composition and properties. Metals, ceramics, polymers and their composite materials are the most widely used biomedical materials. According to their application, biomedical materials can be divided into degradable and absorbable materials, tissue engineering materials and artificial organs, controlled release materials, bionic intelligent materials, etc.

Smart Materials
In the mid-1980s, people proposed the concept of smart materials (Smart Materials or Intelligent Material System): smart materials imitate life systems, can sense environmental changes and change one or more of their own performance parameters in real time, to make desired composite materials or composite materials that can adapt to the changed environment.
Smart materials are a complex material system that integrates materials and structures, intelligent processing, execution systems, control systems and sensor systems. Its design and synthesis span almost all high-tech disciplines. The basic material components that make up smart materials include piezoelectric materials, shape memory materials, optical fibers, electro-(magneto-)rheological fluids, magnetostrictive materials and smart polymer materials. The emergence of smart materials will bring human civilization to a new level, but it is still a long way from the practical stage.

Advanced ceramic materials are generally divided into three categories: structural ceramics, ceramic-based composite materials, and functional ceramics. Most functional ceramics are widely used in the electronics industry and are also commonly referred to as electronic ceramic materials. For example, ceramic insulating materials, ceramic substrate materials, ceramic packaging materials used to manufacture chips, and capacitor ceramics, piezoelectric ceramics, ferrite magnetic materials, etc. used to manufacture electronic devices.
