Abstract

Polyvinyl alcohol (PVA) films have been widely used in industries but they have limited water absorption and tensile strength. Chitin-glucan (CG), is a natural biopolymer with a 3D network structure capable of retaining large amounts of water. In this research, CG obtained from Saccharomyces cerevisiae yeast was added into PVA films to enhance the water absorption and tensile strength. The results showed that by addition of 2% CG micro/nano particles, the tensile strength was highly improved (from 1.4 MPa for PVA film to 5.4 MPa for PVA/CG2% film) while 1, 1.5 and 3% CG had a lower effect on the tensile strength. The degree of swelling for PVA/CG 2% film was also increased to from 175% for PVA film to 310% for PVA/CG2% film. The swelling behavior curves showed a faster water absorption rate for PVA/CG films. Results of this research, enlightens the promising role of CG micro/nano particles in enhancing the mechanical properties and water absorption of PVA films.

新型聚乙烯醇/几丁质-葡聚糖薄膜具有提高拉伸强度和快速吸水性能

聚乙烯醇（PVA）薄膜在工业上得到了广泛的应用，但其吸水性和抗拉强度有限。几丁质-葡聚糖（CG）是一种具有三维网状结构的天然生物聚合物，能够保留大量的水。本研究将从酿酒酵母中提取的CG加入到PVA膜中，以提高膜的吸水率和拉伸强度。结果表明，添加2% CG微纳颗粒可显著提高PVA膜的拉伸强度（PVA/CG2%膜的拉伸强度由1.4 MPa提高到5.4 MPa），而添加1%、1.5%和3% CG对拉伸强度的影响较小。PVA/CG2%膜的溶胀度也由PVA膜的175%提高到PVA/CG2%膜的310%。膨胀行为曲线显示PVA/CG膜的吸水率更快。本研究结果揭示了CG微纳颗粒在提高PVA薄膜力学性能和吸水性方面的重要作用。
