摘要：以笼型八乙烯基倍半硅氧烷（POSS-Vi）、丙烯酰胺（AM）和甲基丙烯酸（MAA）为原料，通过自由基
聚合制备了含氨基、羧基的 POSS/聚合物复合材料〔P(POSS-AM-MAA)〕。采用 FTIR、XRD、TEM 对
P(POSS-AM-MAA)的结构和形貌进行表征。结果表明：P(POSS-AM-MAA)是具有立方笼型结构的 POSS 外围被

Abstract: POSS/polymer composites [P(POSS-AM-MAA)] containing amino and carboxyl groups were
prepared by free radical polymerization from cage-type octavinyloctasilsesquioxane (POSS-Vi), acrylamide
(AM) and methacrylic acid (MAA). The structure and morphology of P(POSS-AM-MAA) were
characterized by FTIR, XRD and TEM. The results showed that P(POSS-AM-MAA) was a material with a
cubic cage structure of POSS surrounded by polymer chains. P(POSS-AM-MAA) combined with
glutaraldehyde accounting for 4% of acid tare mass was used in the tanning process of pickled goat skin.
The effects of amino content, relative molecular mass and composite material dosage on the properties of
leather were investigated. The results indicated that when the amino content was 433 μmol/g, number-average
relative molecular mass of P(POSS-AM-MAA) was 27237, and P(POSS-AM-MAA) dosage was 8% of the
mass of pickled goat skin, combined pH was 8.5, the shrinkage temperature and thickening rate of the
tanned leather were 83.7 ℃ and 107.3%, both higher than those of glutaraldehyde tanned leather. The free
formaldehyde content in the combined tanned leather was 28.3 mg/kg. The tensile strength, elongation at
break and tear strength of the combined tanned leather were 16.5 MPa, 109.5% and 58.8 N/mm, which were
similar to those of glutaraldehyde tanned leather.
