摘　　要：以八乙烯基笼型倍半硅氧烷(POSS-Vi)和衣康酸(IA)为原料,通过自由基聚合制得聚(笼型倍半硅氧烷-衣康酸)[P(POSS-IA)]纳米复合材料。通过FTIR、^(1)HNMR、XRD、TEM对其结构进行了表征,POSS-Vi均匀分散在聚合物基体中,直径在50 nm左右。将P(POSS-IA)应用于坯革鞣制工序中,与聚(衣康酸)[P(IA)]、聚(丙烯酸)[P(AA)]、聚(笼型倍半硅氧烷-丙烯酸)[P(POSS-AA)]、聚(甲基丙烯酸)[P(MAA)]、聚(笼型倍半硅氧烷-甲基丙烯酸)[P(POSS-MAA)]鞣制坯革进行了性能对比。结果表明,P(POSS-IA)鞣制坯革具有较高的收缩温度,达到68.2℃;P(POSS-MAA)鞣制坯革增厚率最大,可达到53.3%;P(POSS-AA)鞣制坯革的抗张强度和撕裂强度最高,分别达到31.6 MPa、59.3 N/mm。坯革的SEM和EDS结果表明,P(POSS-IA)纳米复合材料在鞣制坯革中分散更均匀。Poly(polyhedral oligomericsilsesquioxane-itaconic acid)[P(POSS-IA)]nanocomposite material was prepared by free radical polymerization of octavinylpolyhedral oligomericsilsesquioxane(POSS-Vi)with itaconic acid(IA).Characterization by FTIR,^(1)HNMR,XRD and TEM indicated that the synthesized nanoparticle diameter was about 50 nm with POSS-Vi uniformly dispersed in the polymer matrix.The tanning properties of P(POSS-IA)for trimming the crust leather were further investigated using tanning agents poly(itaconic acid)[P(IA)],poly(acrylic acid)[P(AA)],poly(polyhedral oligomericsilsesquioxaneacrylic acid)[P(POSS-AA)],poly(methacrylic acid)[P(MAA)]and poly(polyhedral oligomericsilsesquioxanemethacrylic acid)[P(POSS-MAA)]as control.The results revealed that the crust leather tanned with P(POSS-IA)exhibited higher shrinkage temperature of 68.2℃while that tanned with P(POSS-MAA)displayed highest thickening rate of 53.3%,and the ones treated with P(POSS-AA)showed highest tensile strength and tear strength,which were 31.6 MPa and 59.3 N/mm,respectively.Meanwhile,SEM and EDS results demonstrated that P(POSS-IA)nanocomposite material was more evenly dispersed in tanned crust leather in comparison to controls.
