The evolution of eco‐friendly and cost efficient energy storage devices is eminent because of depletion of ozone layer and environmental issues. Biopolymer nanocomposites are the most auspicious aspirant to intercept hazardous situations. Chemical functionalization of graphene oxide (GO) is an essential component to avoid agglomeration of nanoparticles and it also helps in end‐use applications. Poly(vinyl alcohol) and chitosan biocomposite is prepared by magnetic stirring method followed by dispersion of nanofiller by ultrasonication process. The aim is to emphasize on usage of metal‐free material that is bionanocomposite, to exploit and enhance electrical properties of resultant product. The major drawback of chitosan is its low mechanical strength which can be overcome by employing GO and poly(vinyl alcohol). Scanning electron microscopy and transmission electron microscopy studies examined the uniform distribution of GO nanoparticles and functionalization improved the dispersion by creating nitrogen and hydroxyl moieties, this increases the intermolecular interactions between nanofiller and biopolymer matrix. The investigation of thermal analysis revealed the improved thermal stability and lower weight reduction on incorporation of GO and chemically functionalized GO. © 2019 Wiley Periodicals, Inc. J.

超级电容器应用中功能化氧化石墨烯填充的PVA-壳聚糖生物混合物的电化学评估

由于臭氧层的枯竭和环境问题，环保和具有成本效益的储能设备的发展势在必行。生物聚合物纳米复合材料是拦截危险情况的最吉祥的吸气剂。氧化石墨烯（GO）的化学功能化是避免纳米粒子团聚的重要组成部分，还有助于最终应用。通过磁力搅拌法制备聚乙烯醇和壳聚糖生物复合材料，然后通过超声处理分散纳米填料。目的是强调使用生物合成的无金属材料，以开发和增强最终产品的电性能。壳聚糖的主要缺点是其机械强度低，可以通过使用GO和聚乙烯醇来克服。扫描电子显微镜和透射电子显微镜研究检查了GO纳米颗粒的均匀分布，并通过产生氮和羟基部分功能化改善了分散性，这增加了纳米填料与生物聚合物基质之间的分子间相互作用。热分析的研究表明，通过掺入GO和化学官能化的GO，可以提高热稳定性并降低重量。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学热分析的研究表明，通过掺入GO和化学官能化的GO，可以提高热稳定性并降低重量。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学热分析的研究表明，通过掺入GO和化学官能化的GO，可以提高热稳定性并降低重量。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48610。
