多面体笼型聚倍半硅氧烷(polyhedral oligomeric silsesquioxanes,POSS)是一种内核为Si—O—Si骨架笼形结构、外壳连接有机反应性基团R的无机/有机纳米结构粒子,能够以多种方式引入聚合物中,并且通过溶液组装提供独特的疏水疏油表面。在介绍POSS结构特点的基础上,介绍了POSS基含氟聚合物的合成、组装涂层性能,以及POSS基含氟聚合物在文物保护中的应用。 Polyhedral oligomeric silsesquioxanes (POSS) is a kind of inorganic / organic nanostructured particles whose core is Si-O-Si skeleton and whose outer shell is connected with organic reactive group R, The introduction of polymers into the polymer provides a unique hydrophobic and oleophobic surface through solution assembly. Based on the introduction of POSS structural features, the synthesis of POSS-based fluoropolymers, the properties of assembly coatings and the application of POSS-based fluoropolymers in the protection of artifacts are introduced.
