摘要

塑料在我们的日常生活中无处不在。然而,使用石化塑料作为包装材料会导致不可再生资源的枯竭,从而导致油价上涨和经济危机。此外,这些石化塑料由于其不可生物降解性而引发了环境污染问题。因此,有必要开发一种可生物降解和环保的替代包装材料。琼脂是从海藻中提取的,是大量可用的聚合物之一。然而,适度的拉伸强度和热稳定性限制了其应用。作为一个进步,通过原位还原聚合物基体中的GO制备了琼脂/还原氧化石墨烯(RGO)复合材料。发现复合材料的拉伸强度在2%的RGO负载下增加了55%。复合材料的导电性和热性能也得到了改善。导电性的存在表明,除了包装之外,琼脂/RGO复合材料还可以作为产生超级电容器的电容器板和电场诱导的伤口愈合材料具有潜在的应用。

Preparation of Biodegradable Reduced Graphene Oxide/Agar Composites by In Situ Reduction of Graphene Oxide
Plastics are ubiquitous in our daily life. However, the use of petrochemical-based plastic as packaging materials causes the depletion of non-renewable resources, thereby leading to an increase in oil prices and economic crises. Moreover, these petrochemical plastics raise the issue of environmental pollution due to their non-biodegradability. Owing to this, there is a need to develop an alternative biodegradable and eco-friendly packing material. Agar, which is extracted from seaweeds, is one of the abundantly available polymers. However, moderate tensile strength and thermal stability restrict its application. As a step forward, agar/reduced graphene oxide (RGO) composites were prepared by in situ reduction of GO in the polymer matrix. The tensile strength of the composite was found to increase by 55% at 2% RGO loading. The electrical conductivity and thermal properties of the composite were also improved. The presence of conductivity suggested that apart from packaging, agar/RGO composites can also have potential applications as capacitor plates creating a supercapacitor and as electric field-induced wound healing material.
