Unformatted text preview: compatibility and interfacial bonding between clay and elastomer, which in turn increased the restriction to elastomer chain mobility. For T-SiO 2 , the elastomer chains were chemically bonded to the nanofiller and the crosslink density of the elastomer was also increased. Therefore, T-SiO 2 showed even higher restriction to the chain mobility than FS-clay. As a result, T-SiO 2 led to a larger increase in elastomer T g compared to FS-clay. The other nanofillers, i.e. S-clay, T-G, and UT-SiO 2 , caused smaller increase in T g due to their lack of strong interactions with the elastomer. (a)...
