摘要

研究了通过受控还原氧化石墨烯（GO）来增强环氧纳米复合材料所产生的微观结构特征的变化。研究了在环氧树脂中添加不同负载量（0.1-0.5 wt%）的 RGO 的效果，重点关注材料对机械和热性能的响应。环氧树脂与 RGO 之间牢固的界面结合归因于石墨烯剥离分层几何形状的较高表面积，这也是纳米复合材料物理性能增强的关键因素。已确定二维纳米填料的最佳掺入量可产生协同效应，从而在设计用于高性能电子设备的热界面材料中建立一个渗透网络。

Structural, Mechanical and Thermal Behaviour of Graphene-Epoxy Polymer Matrix Nanocomposites

The change in characteristics in the microstructural features of epoxy nanocomposites created by reinforcing with graphene oxide (GO) obtained by controlled reduction of GO was investigated. The effects of adding various loadings (0.1–0.5 wt%) of RGO in epoxy resin were examined, with a focus on the material’s response toward mechanical and thermal properties. The robust interfacial bonding between epoxy resin and RGO is attributed to the higher surface area of the exfoliated layered geometry of graphene and is a key factor contributing to the enhanced physical properties in nanocomposite. The optimal incorporation of 2D nanofillers has been determined to induce a synergistic effect, thereby establishing a percolating network in thermal interface materials designed for high-performance electronic device.
