Research Progress on Preparation of Aerogel Materials and Their Application in Plastics
Aerogels have a three-dimensional network skeleton structure,which has low density and low thermal conductivity.Functional polymer materials prepared using aerogels have shown excellent properties in specific fields.The development history,types,and preparation methods of aerogels both at home and abroad are introduced,and the modification methods of aerogels such as aging reinforcement,polymer fiber reinforcement,and polymer crosslinking are discussed.The application of aerogels in functional plastics is summarized,and the effects of aerogels on the properties of thermal insulation and flame retardant functional plastics,the adsorption capacity of adsorption materials,the reaction of catalyst carrier plastics and the properties of microwave absorbing plastics are analyzed.The application of aerogels in civil fabrics is prospected.
