摘要

采用两步水热法制备了具有核壳结构的二硫化钼/硫化铜(MoS₂/CuS)纳米杂化材料,然后将其作为填料与环氧树脂复合,制备了环氧树脂/二硫化钼/硫化铜(EP/MoS₂/CuS)复合材料。通过X射线衍射(XRD)、扫描电镜(SEM)和能谱(EDS)分析了产物的化学组成和形貌特征,并利用多功能摩擦磨损试验机对EP复合涂层的摩擦磨损性能进行了探究。结果表明:MoS₂纳米片均匀地包覆在CuS表面,形成了以MoS₂为壳,CuS为核的杂化体。单体MoS₂、CuS和杂化材料MoS₂/CuS均能改善EP的摩擦学性能,其中杂化体MoS₂/CuS的改善效果最好,当MoS₂/CuS质量分数为1.25%时,EP/MoS₂/CuS复合材料的摩擦系数和磨损率较纯EP分别降低了36.8%和35.7%。

Abstract

The molybdenum disulfide/copper sulphide (MoS₂/CuS) nanohybrid materials with core-shell structure were synthesized by two-step hydrothermal method,and then the MoS₂/CuS hybrid materials were used as fillers to composite with epoxy resin (EP) to prepare the EP/MoS₂/CuS composites.The morphology and chemical composition of the prepared products were characterized by XRD,SEM and EDS,and the friction and wear performance of EP composite coatings was investigated using a multifunctional friction and wear tester.The results showed that the MoS₂ nanosheets were uniformly coated on the CuS surface,forming a hybrid with MoS₂ as the shell and CuS as the core.The monomer MoS₂,CuS and the hybrid MoS₂/CuS could improve the tribological properties of EP,among which the MoS₂/CuS hybrid presented the optimal enhancement effect.Compared with pure EP,when the mass fraction of MoS₂/CuS hybrid was 1.25wt%,the friction coefficient and wear rate of EP/MoS₂/CuS composites were reduced by 36.8% and 35.7%,respectively.
