摘要
采用十六烷基三甲基溴化铵作为有机插层剂对海泡石进行了有机化处理,该有机化海泡石粒子在苯乙烯和丙烯腈单体中很容易地均匀分散并形成稳定的胶体溶液。通过对分散有海泡石的苯乙烯和丙烯腈进行自由基聚合制备了聚苯乙烯-丙烯腈/海泡石纳米复合材料,并对聚苯乙烯-丙烯腈/海泡石复合材料的结构进行了表征。结果表明聚苯乙烯-丙烯腈的大分子链插入到海泡石片层间,形成了部分插层部分剥离型纳米复合材料。
The organophilic sepiolite is obtained by sepiolite modified by cetyhrimethylammonium bromide. The organophilic sepiolite particles are easily dispersed and swollen in styrene and acrylonitile monomer. Poly （styrene- acrylonitile）/sepiolite nanocomposites are prepared by free radical polymerization of styrene and acrylonitile containing dispersed sepiolite. The composites are characterized. The results show that the macromolecular chain of polystyreneacrylonitile is inserted into the laminatedlayers of sepiolite to form interposive partially and exfoliative partially nanocomposite material.
