Abstract

In this work, UV-curable resin poly (ethylene glycol) diacrylate (PEGDA) was reinforced with three different types of nanofillers: pristine graphene (G), multiwalled carbon nanotubes (MWNTs), and a hybrid of MWNTs and graphene 70/30 in mass ratio (Hyb). PEGDA was mixed homogenously with the nanofiller oligomer by shear mixing and then photopolymerized, affording thin, stable films. The thermomechanical properties of the afforded nanocomposites indicated the superior reinforcing ability of pristine graphene compared with MWNTs and an intermediate behavior of the hybrid.

摘要

在这项工作中，使用三种不同类型的纳米填料增强了紫外光固化树脂聚乙二醇二丙烯酸酯（PEGDA）：原始石墨烯（G）、多壁碳纳米管（MWNTs）和质量比为 70/30 的 MWNTs 和石墨烯的混合物（Hyb）。PEGDA 通过剪切混合均匀地与纳米填料低聚物混合，然后进行光聚合，得到薄且稳定的薄膜。所得到的纳米复合材料的热机械性能表明，与 MWNTs 相比，原始石墨烯具有优异的增强能力，而混合物则表现出中等行为。
