摘　　要：用碱溶液对苯乙烯-马来酸酐共聚物(SMA)和SMA与有机蒙脱土(OMMT)熔融插层后的SMA/OMMT纳米复合材料分别进行处理,通过高温热分解试验研究了表面碱化处理对2种材料热稳定性能的影响。研究表明:表面碱化处理可以使SMA在高温下的热稳定性能与成炭性能显著提高,而SMA/OMMT纳米复合材料本身具有良好的热稳定性和阻燃性,碱处理对它的影响较小;在相同条件下,经过KOH溶液处理材料的耐热性能比NaOH溶液处理材料的更好。SMA and melt-intercalated SMA/OMMT nanocomposite were surface-treated with alkaline solutions and the effects of alkaline treatment on the thermal stability of both materials were investigated by high temperature pyrolysis.It is demonstrated that surface basification treatment can improve the thermal stability and charring capacity of SMA noticeably. As the SMA/OMMT nanocomposite has excellent thermal stability and flame retardancy originally,the influence of surface alkaline treatment on its thermal stability is not obvious. Under the same conditions,the effect of KOH solution treatment is more remarkable than that of NaOH.
