3 结论

（1）以 POSS-Vi、IA 为原料，通过自由基聚合制
1
得了 P（POSS-IA）纳米复合材料，通过 FTIR、HNMR、
XRD 对其结构进行了表征，TEM 表明，POSS-Vi 在
聚合物基体中均匀分散，直径为 50 nm 左右。
（2）将 P（POSS-IA）应用于山羊酸皮鞣，与 P
（IA）、P（AA）、P（POSS-AA）、P（MAA）、P（POSS-
MAA）鞣制坯革性能对比。结果表明，P（POSS-IA）
鞣制坯革具有较高的收缩温度，为 68.2 ℃；P（POSS-
MAA）鞣制坯革具有较高的增厚率，为 53.3%；P
（POSS-AA）鞣制坯革的抗张强度和撕裂强度较高，
分别为 31.6 MPa、59.3 N/mm。P（POSS-IA）纳米
复合材料在鞣制坯革中分散更均匀。P（POSS-IA）
对 皮胶原 纤维 具有鞣 制和 填充性 能， 拓宽 了
POSS-Vi 在皮革行业的应用；并且 P（POSS-IA）中
含有活性基团，可以与非铬金属盐等无铬鞣剂一起
使用，改善非铬金属盐等无铬鞣剂本身缺陷，协同
提升皮胶原纤维鞣制性能，为研发环保型鞣剂材料
提供了新方法和新思路。
