溶胶-凝胶法制备PVA/SiO_2杂化材料

Sol-Gel Method for the Preparation of PVA/SiO_2 Heteropolymer

以Na2SiO3为无机前驱体,采用溶胶-凝胶(Sol-Gel)法制备了PVA/SiO2杂化材料,并研究了其主要物理性能。结果表明,PVA/SiO2杂化材料的力学性能明显优于PVA/白炭黑材料。

With Na 2 SiO 3 used as inorganic medium,PVA /SiO 2 heteropolymer was prepared by Sol-Gel method,and its mechanical properties were studied.The results showed that the me chan ical properties of PVA/SiO 2 heteropolymer were markedly superior to those of PVA/silica.
