Abstract Biopolymer nanocomposites due to their distinctive properties and biodegradability can sustainably replace conventional polymers. Biopolymers have a massive spectrum in hydrogels, environmental, biomedical field, bio-coating, sensors, etc. The rheological study has been investigated to essay the viscoelastic behavior of the aqueous solution and thin films of GO reinforced PVA nanocomposite thin films. The resultant nanocomposite films have the potential to be employed in the packaging and coating domain. The viscosity curve purports the shear-thinning behavior of the aqueous solution of PVA-GO nanocomposite. The data evaluated from Ostwald (Power law) representing flow curves could also be attributed to pseudoplastic behavior in which coefficient p

使用用于包装应用的 ostwald 模型对氧化石墨烯接枝 PVA 生物杂化物的粘弹性研究

摘要 生物聚合物纳米复合材料由于其独特的性能和生物降解性，可以可持续地替代传统聚合物。生物聚合物在水凝胶、环境、生物医学领域、生物涂层、传感器等方面具有广泛的应用范围。流变学研究已被研究以研究 GO 增强 PVA 纳米复合薄膜的水溶液和薄膜的粘弹性行为。所得纳米复合薄膜有可能用于包装和涂层领域。粘度曲线表明 PVA-GO 纳米复合材料的水溶液的剪切稀化行为。从代表流动曲线的 Ostwald（幂律）评估的数据也可归因于假塑性行为，其中系数 p
