STUDY ON THERMAL PROPERTIES OF GRAPHENE OXIDE MODIFIED THERMOSETTING PHENOLIC RESIN

Abstract

Abstract: In this paper, the thermosetting phenolic resin modified by graphene oxide (GO) was prepared by in situ polymerization and solution blending. The influence of the addition content of GO and the adding way on the thermal properties of phenolic resin was analyzed. For the modified resin prepared by in situ polymerization, the T_g decreased slightly with the addition of GO. Besides, the residual carbon rate and the thermal decomposition temperature of the first stage increased firstly and then decreased. Compared with the resin prepared by in situ polymerization, the resin prepared by solution blending had a better heat resistance and a narrower GO dispersion scale.

Key words: graphene oxide, phenolic resin, pyrolysis property, morphology
