摘　　要：通过离子交换法将烯丙基三苯基溴化(AP)交换到钠基蒙脱土(Na-MMT)的层间制备改性蒙脱土。采用FT-IR、XRD、TEM和TG等对AP改性前后MMT的结构及性能进行表征。结果表明:AP能够与MMT层间的钠离子发生离子交换反应形成有机蒙脱土;经过AP改性处理后MMT的层间距由1.49 nm变为1.85 nm,其结构变得疏松;AP改性MMT具有很好的耐热性能,热分解起始温度达320℃。In order to prepare bismaleimide （BMI）/montmorillonite nanocomposites with high performance, Na-montmorillonite （Na-MMT） was modified with allyl-tri-phenyl phosphonium bromide （AP） via ion-exchange method. The structures and properties of Na-MMT and AP-modified MMT were characterized by FT-IR, XRD, TEM and TG. The results show that AP has intercalated into the layers of Na-MMT, and the spacing of AP-modified MMT layers increases from 1.49nm to 1.85 nm. Moreover, AP-modified MMT possesses good thermo-stability as indicated by that initial thermal decomposition temperature arrives at 320℃, and the ion-exchange rate of AP-modified MMT is 66.3 % according to TG curves.
