The carbon–carbon double bonds (C=C) and graphene oxide (GO) in nitrile butadiene rubber (NBR) latex were reduced simultaneously by a novel one-pot to prepare the hydrogenated nitrile butadiene rubber/reduced graphene oxide (HNBR/RGO) nanocomposite in this study, using a hydrazine hydrate/hydrogen peroxide/copper sulfate catalyst. It is a water-based environmentally friendly and time-saving method where no organic solvent has served in the reduction process and hydrazine hydrate is completely consumed and will not harm the environment after the reduction process. HNBR/RGO can improve the electrical and thermal conductivity of HNBR, and the thermal conductivity of HNBR/RGO present better stability at high temperature (160 °C). RGO sheets are beneficial to shorten the curing time and increase cured rate index. And introducing RGO sheets may improve the thermal-oxidative aging resistance. The relationship between aging lifetime and temperature in HNBR/RGO can be estimated, and provide an opportunity for the practical application of HNBR.

乳胶法一锅还原法制备氢化丁腈橡胶/还原氧化石墨烯纳米复合材料

通过新型一锅法同时还原丁腈橡胶（NBR）胶乳中的碳碳双键（C=C）和氧化石墨烯（GO），制备氢化丁腈橡胶/还原氧化石墨烯（HNBR/RGO）本研究中的纳米复合材料，使用水合肼/过氧化氢/硫酸铜催化剂。它是一种水性环保、省时的方法，还原过程中不使用有机溶剂，水合肼被完全消耗掉，还原后不会对环境造成危害。HNBR/RGO 可以提高 HNBR 的导电性和导热性，并且 HNBR/RGO 的导热性在高温（160°C）下表现出更好的稳定性。RGO片材有利于缩短固化时间，提高固化速度指数。并且引入RGO片材可以提高抗热氧化老化性。可以估算HNBR/RGO中老化寿命与温度之间的关系，为HNBR的实际应用提供机会。
