Abstract: In order to broaden the application field of nano-molybdenum disulfide (MoS2),the surface functionalization of MoS2 powder was carried out using silane coupling agent KH550 to improve the compatibility between molybdenum disulfide powder and polymer matrix. The structure of MoS2 powder before and after surface functionalization was characterized by infrared spectroscopy and scanning electron microscopy. The surface functionalized MoS2 powder was applied to the synthesis of phenolic resin and the foaming experiment. The results show that the surface of MoS2 powder is successfully coated with organic matter,and the surface functionalized MoS2 powder is improved in hydrophobic and lipophilic properties. The surface functionalized MoS2 is uniformly dispersed in the phenolic foam material,and the comprehensive performance of the phenolic foam is significantly improved.

Keywords: molybdenum disulfide; silane coupling agent; surface functionalization; phenolic resin
