2、Silane Coupling Agent

The general structure of silane coupling agents are (RO)3 -Si-R‘-X, where X is an organofunctional group, R‘ is a small alkylene linkage, and RO is a hydrolyzable group such as an alkoxy group (Pape 1996). The organofunctional group and the alkoxy group can form strong bonds with the polymer matrix and with the filler particles, respectively.
