氧烷-衣康酸)〔P(POSS-IA)〕纳米复合材料。通过 FTIR、 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。

Abstract: Poly(polyhedral oligomericsilsesquioxane-itaconic acid) [P(POSS-IA)] nanocomposite material
was prepared by free radical polymerization of octavinylpolyhedral oligomericsilsesquioxane (POSS-Vi)
1
with itaconic acid (IA). Characterization by FTIR, 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 oligomericsilsesquioxane-
acrylic acid) [P(POSS-AA)], poly(methacrylic acid) [P(MAA)] and poly(polyhedral oligomericsilsesquioxane-
methacrylic 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.
