摘　　要：采用原位聚合法和溶液共混法制备氧化石墨烯(GO)改性热固性酚醛树脂,分析GO的加入量和加入方式对酚醛树脂热性能的影响。在原位聚合法制备的改性树脂中,GO的引入使酚醛树脂的Tg略有下降,随着GO加入量的增加,树脂的残碳率和第一阶段的热分解温度先升高后降低;相比于原位聚合法,溶液共混法制备的改性树脂中,树脂的耐热性更佳,GO的分散尺度更小。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 Tg decreased slightly with the addition of GO. Besides, the residual carbon rate and the thermal decomposition tempera- ture of the first stage increased firstly and then decreased. Compared with the resin prepared by in situ polymeriza- tion, the resin prepared by solution blending had a better heat resistance and a narrower GO dispersion scale.
