摘要

Inthisarticle，nanocompositesbasedonChitosan(CS)/polyvinylalcohol(PVA)andgrapheneoxide (GO)nanoparticleswerepreparedbycastingthestableaqueousmixtureofthecomponentsinamold。采用傅里叶变换红外光谱(FTIR)，X-raydiffractions(XRD)andviscositymeasurement.ScanningElectronMicroscopy(SEM) resultsindicatedthattheGOwasuniformlydispersedinthepolymermatrix对所制备的纳米复合材料进行了表征。Thewateruptakeability ofnanocompositesincreasedwithanincreasingthePVAcontent。While，theadditionofGOtoCS/ PVAleadtoadecreaseinthedegreeofwaterabsorption。Accordingtotherheologicalanalysisthe viscosityofthesamplesdecreasedwithincreasingtheGOweightpercentinCS/PVAmixture。关键词壳聚糖，氧化石墨烯，纳米复合材料，粘度测试，吸水率

Synthesis and Characterization of Chitosan-Poly Vinyl Alcohol-Graphene Oxide Nanocomposites

Inthisarticle,nanocompositesbasedonChitosan(CS)/polyvinylalcohol(PVA)andgrapheneoxide (GO)nanoparticleswerepreparedbycastingthestableaqueousmixtureofthecomponentsinamold. The prepared nanocomposites were characterized using Fourier-transform infrared spectroscopy (FTIR),X-raydiffractions(XRD)andviscositymeasurement.ScanningElectronMicroscopy(SEM) resultsindicatedthattheGOwasuniformlydispersedinthepolymermatrix.Thewateruptakeability ofnanocompositesincreasedwithanincreasingthePVAcontent.While,theadditionofGOtoCS/ PVAleadtoadecreaseinthedegreeofwaterabsorption.Accordingtotherheologicalanalysisthe viscosityofthesamplesdecreasedwithincreasingtheGOweightpercentinCS/PVAmixture.
