Abstract

The graphene/nanonickel composites(Ni/RGO) were prepared by liquid phase reduction method, and the graphene/nanonickel epoxy composites(Ni/RGO/EP) were prepared by in-situ polymerization method. The glass transition temperature (Tg) of the modified epoxy resin was increased by 19°C compared to EP with 2.1 wt% Ni/RGO loading. The tensile strength and hardness increased by 65% and 18%, the impact strength is increased by 10.053 KJ·m−2 compared to EP, and the shear strength reaches 34.78 MPa for the Ni/RGO/EP with 1.7 wt% Ni/RGO loading. It can be seen, that the addition of Ni/RGO greatly improves the heat resistance and mechanical properties of epoxy resin when the Ni/RGO are evenly dispersed into the epoxy resin by emulsion dispersion method.

Ni/RGO 增强环氧树脂复合材料的制备与力学性能

采用液相还原法制备了石墨烯/镍复合材料（Ni/RGO），采用原位聚合法制备了石墨烯/镍环氧树脂复合材料（Ni/RGO/EP）。与添加 2.1 wt% Ni/RGO 的 EP 相比，改性环氧树脂的玻璃化转变温度（Tg）提高了 19°C。与 EP 相比，添加 1.7 wt% Ni/RGO 的 Ni/RGO/EP 的拉伸强度和硬度分别提高了 65% 和 18%，冲击强度提高了 10.053 KJ-m-2，剪切强度达到 34.78 MPa。由此可见，当采用乳液分散法将 Ni/RGO 均匀分散到环氧树脂中时，Ni/RGO 的添加大大提高了环氧树脂的耐热性和机械性能。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
