通过悬浮聚合，将多壁碳纳米管（MWNTs）引入苯乙烯-二乙烯基苯共聚物（PS-DVB）的交联网络中。首先用氯甲基甲醚通过Friedel-Craft反应引入氯甲基，制备了与MWNTs交联的PS-DVB；然后将氯甲基化产物与三甲基胺反应得到目标聚合物/碳纳米管复合材料：PS-DVB/MWNT离子交换树脂。用傅立叶变换红外光谱、热重分析、拉曼光谱和X射线光电子能谱对复合材料进行了表征。结果表明，MWNTs成功地融入到聚合物网络中。PS-DVB/MWNT离子交换树脂的理化性能与对照样品基本一致。利用其优异的抗湿性，考察了其在环氧乙烷水合反应中的催化性能。同时，作为催化剂，它表现出良好的稳定性，在长时间运行中转化率和选择性不会下降。2009年Wiley期刊公司JAPPL Polym Sci,2010
