Abstract

We fabricate mesoporous silica/silicone composites in a simple way and systematically examine their thermal stability, swelling characteristic, mechanical strength, and transparency. Simple calculations show that more than 90 vol% of mesopores are filled with silicone rubbers. Compared to non-porous silica/silicone composites, mesoporous silica/silicone composites showed a lower coefficient of linear thermal expansion (CTE). In addition, dramatic improvements of the tensile strength and Young's modulus are obtained with mesoporous silica/silicone composites. Furthermore, mesoporous silica/silicone composites show higher transparency than non-porous silica/silicone composites.
