层状聚乙烯醇／氧化石墨烯纳米复合膜的制备及性能研究
Preparation and performance of poly (vinyl alcohol)/graphene oxide nanocomposite films w ith layered structure
摘要
Abstract
The graphene oxide is prepared by modified Hummers method , and the polyvinyl alcohol/graphene oxide(PVA/GO) nanocomposite films with a layered structure simply is prepared by ultrasonic dispersion and film-casting method . T he microstructures of the nanocomposite films are investigated using FTIR ,TEM ,SEM and XRD . The thermal stability ,mechanical properties and water-resistance of the nanocomposite films are also tested . The experimental results indicate that GO sheets are well dispersed in the PVA matrix , and crystalline structure of PVA is not affected by adding GO . Thermal stability , water-resistance and mechanical properties of the nanocomposite films are improved by strong interaction between PVA and GO .关键词
