Abstract

Epoxy–silica hybrids with interfacial bonding using aminophenyltrimethoxysilane APTMOS have been prepared by the sol–gel process In a sequential polymerization procedure the amine groups present on the APTMOS were used to partially cure diglycidyl ether of bisphenolA DGEBA whereas the methoxy groups created silicanetwork simultaneously through the sol–gel process Complete curing and crosslinking were carried out later using curing agent jeffamine D400 at higher temperature The nature of silica network structure chemically bonded with the epoxy chains was studied by Fourier transformed infrared spectroscopy and the morphology of the hybrid through scattering electron and atomic force microscopies The viscoelastic properties of the resulting hybrids were measured through dynamical thermal mechanical analysis The effect of interphase bonding of the resulting hybrids and their thermal mechanical properties are compared with the similar DGEBA epoxy matrix where unbonded silica network was produced from tetraethoxysilane The properties of the hybrids using APTMOS show considerable improvement in thermal mechanical properties and the coefficient of thermal expansion is reduced in contrast to the uncompatiblized systemThe authors acknowledge the Research Administration of KU for the grant under Project SC 07/09 The technical support from the E M unit Project GS 03/01 and the general facilities Project 01/01 under SAF program is greatly appreciated For the thermogravimetric analysis work under Project GE03/08 is also appreciated
