摘　　要：用甲基丙烯酸(methacrylicacid,MAA)在钠基蒙脱土(montmorillonite,MMT)层间直接原位插层聚合制备了聚甲基丙烯酸/蒙脱土(polymethacrylicacid/montmorillonite,PMAA/MMT)纳米复合材料。以蒙脱土的层间距、插层进入蒙脱土层间的聚合物含量及应用于皮革鞣制的实验结果为考察指标,对制备过程中的引发剂用量及蒙脱土用量进行了单因素实验研究。结果表明:所制备的PMAA/MMT纳米复合材料属于剥离型纳米复合材料,应用于皮革鞣制所得坯革的增厚率及湿热稳定性均有较大提高。A polymethacrylic acid/montmorillonite （PMAA/MMT） nanocomposite was prepared via the monomer in situ polymerization. Methacrylic acid was polymerized directly in Na-montmorillonite layers by flee radical initiation. The impacts of the initiator and MMT dosage on the nanocomposite structure were studied by mono-factor experiment with the interlayer space of MMT, polymer content in MMT interlayer galleries and application results as review targets. The results show that the PMAA/MMT nanocom- posite formed is an exfoliated nanocomposite. The increment ratio and wet-heat resistance of tanned leather polymethacrylic acid/ montmorillonite were improved.
