通过光聚合获得的透明导电氧化石墨烯-聚乙二醇二丙烯酸酯涂层
Transparent and conductive graphene oxide-polyethylenglycol diacrylate coatings obtained by photopolymerization
摘要：
以水分散氧化石墨烯片为原料，通过光聚合法制备了石墨烯-聚乙二醇二丙烯酸酯树脂复合材料。发现石墨烯片在树脂系统内经历优异的形态分布，产生相对于纯树脂具有未改变的热性质的透明复合材料，其在低至0.02%wt的氧化石墨烯的负载比下是导电的。基于光聚合的方法提供了一种简单、节能和环境友好的技术，可以在涂料技术中找到广泛的应用，主要用于电磁屏蔽和抗静电涂料。
英文摘要：
Water dispersed graphene oxide sheets were used to prepare graphene-polyethylenglycol diacrylate resin composites by photopolymerization. It was found that graphene sheets undergo excellent morphological distribution within the resin system, giving rise to transparent composites with unaltered thermal properties with respect to the neat resin, that are electrically conductive at loading ratios as low as 0.02 %wt of graphene oxide . The proposed strategy based on photopolymerization provides an easy, energy-saving and environmental friendly technique that can find a wide application in coating technology, mainly for electromagnetic shielding and antistatic coatings.
