| 英文摘要 | Chemical surface modification of fibrous silicate with polyvinylpyrrolidone (PVP) or its derivates via grafting-from and grafting-to methods was investigated. The grafting-from method was based on the immobilization of reactive end functional groups of silane coupling agents on silicate surface, followed by chain growth via radical polymerization of N-vinylpyrrolidone (NVP) to form grafted polymers with different molecular weight. In the grafting-to method, a novel copolymer PVP-171 with side functionalized groups and designed molecular weight was synthesized by radical polymerization of NVP and vinyltrimethoxysilane (DB171) and then bonded to the surface of fibrous silicates. Evidences from FTIR, XPS, TGA, and BET test indicate that there are similar to 68,000 reactive sites per square meters on the surface with the grafted vinyl concentration of 59 mequiv per 100 g of clay. XRD patterns and SEM images demonstrate that grafting modification was bound on the silicate surface and make the surface rough with the increase of graft-loading quantity. In contrast with grafting-to approach, grafting-from approach facilitates the dispersion of silicates in PET composites. (C) 2008 Wiley Periodicals, Inc. J Appl Polym Sci 111: 566-575, 2009 |
