Bio-based degradable new materials are environmentally friendly materials prepared from renewable biomass such as plant starch, agricultural and forestry straw, bamboo fiber and microbial fermentation polyester. They can be naturally degraded under natural environment or industrial composting conditions, which can effectively reduce the accumulation of plastic waste and microplastic pollution, and lower industrial carbon emissions. They are green new materials in line with the dual carbon goals and circular economy development.

Graphene is a two-dimensional nano new material composed of single-layer carbon atoms. It has extreme electrical conductivity, thermal conductivity, flexibility and ultra-large specific surface area, as well as multiple excellent characteristics such as ultra-thin thickness, ultra-high strength and acid and alkali corrosion resistance. As a new generation of cutting-edge functional new materials, it is applied in many core fields including new energy, electronics, construction, environmental protection and medical treatment.
