摘要：为拓宽纳米二硫化钼(MoS₂)的应用领域,使用硅烷偶联剂KH550对MoS₂粉体进行表面功能化处理,以改善二硫化钼粉体与高分子聚合物基体间的相容性,并对表面功能化前、后的MoS₂粉体进行红外光谱及扫描电镜结构表征;功能化MoS₂粉体应用于酚醛树脂的合成并进行发泡实验,测试泡沫试样力学拉伸断口性能。结果表明:二硫化钼粉体表面被有机物成功包覆,功能化的MoS₂粉体疏水亲油性提高,在酚醛泡沫材料中分散均匀,并使其综合性能显著提升。

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．
