摘要
采用共混法制备了纳米纤维素(NCC)/改性纳米二氧化硅(SiO2)/聚乙烯醇(PVA)共混膜。傅里叶变换红外(FTIR)光谱分析结果表明NCC/改性纳米SiO2/PVA共混膜的共混模式为存在氢键作用力的简单物理共混。力学性能分析结果表明NCC/改性纳米SiO2/PVA共混膜较PVA膜具有较高的拉伸强度,其拉伸强度平均值为128.41 MPa。热学性能分析结果表明NCC/改性纳米SiO2/PVA共混膜较PVA膜具有较好的热稳定性,其最大热失重温度为238℃。扫描电子显微镜(SEM)图分析结果表明NCC/改性纳米SiO2/PVA共混膜样品的表面和断面形貌较规整。
Nanocrystalline cellulose（NCC）/modified nano-silica（SiO2）/polyvinyl alcohol（PVA） blend membrane was prepared by blending method.The results of fourier transform infrared（FTIR） spectroscopy analysis showed that blending mode of NCC/modified nano-SiO2/PVA blend membrane was simple physical blending of hydrogen bonding interactions.The results of mechanical performance analysis showed that tensile strength of NCC/modified nano-SiO2/PVA blend membrane was higher than that of PVA membrane,the average tensile strength of NCC/modified nano-SiO2/PVA blend membrane was 128.41MPa.The results of thermal performance analysis showed that the thermal stability of NCC/modified nano-SiO2/PVA blend membrane was better than that of PVA membrane,the maximum thermal weight loss temperature of NCC/modified nano-SiO2/PVA blend membrane was 238 ℃.The results of scanning electron microscopy（SEM） analysis showed that surface morphology and cross-section morphology of NCC/modified nano-SiO2/PVA blend membrane was more structured.
