Abstract: |
Silicone foams have flame retardancy,high and low temperature resistance and chemical stability due to their unique inorganic - organic hybrid structure. Because of large amount of cellular structure,they have excellent properties such as damping,light weight,sound insulation,heat insulation and sound absorption. They are widely used in biomedicine,aerospace,electronic equipment and other fields. The preparation methods of silicone foams include chemical foaming method(internal foaming and external foaming with addition of foaming agent),physical foaming method(3D printing,pores forming by solvent dissolution,and inert gas method),mold method,radiation crosslinking method,and mixed foaming method. With the deepening of research on silicone foams,development of green materials and process,functionalization and cost reduction are the important directions for future research. |
