Preparation of low-CTE composite using new alkoxysilyl-functionalized bisphenol A novolac epoxy and its CTE enhancement mechanism

In order to prepare the epoxy material with high dimensional stability, alkoxysilyl-functionalized bisphenol A novolac epoxy was newly synthesized. The composite film of the new epoxy was prepared by adding polymer binder and its coefficient of thermal expansion (CTE) was measured. After alkoxysilyl-modification, the thermal expansion performance of the epoxy composite was significantly improved. At 80 wt% of silica added, the epoxy composite...
