MoS2/C复合纳米粒子对双马来酰亚胺树脂的改性研究

MODIFICATION OF BISMALEIMIDE RESIN BY MOS2/C NANOPARTICLES AND ITS PROPERTIES

由于传统MoS2纳米粒子在高温高压条件下容易氧化,且在有机树脂中难以长期稳定存在,本论文选择钼酸铵作为钼源,硫代乙酰胺作为硫源,同时以活性炭作为碳源,通过水合热法制备出MoS2/C复合粒子,并以其作为填料对双马来酰亚胺树脂(BMI)进行改性,制备出MoS2/C/BMI树脂复合材料,并研究了MoS2/C复合粒子含量对MoS2/C/BMI树脂复合材料力学性能、摩擦学性能以及耐湿性能的影响。结果表明:所得的MoS2/C复合粒子较传统MoS2纳米粒子颗粒更小更均匀;当MoS2/C复合粒子含量为6.0%(质量分数)时,MoS2/C/BMI树脂复合材料的综合性能最优。

As traditional MoS2 nanoparticles are easily oxidated under the conditions of high temperature and high pressure, and it is hard to exist for a long time in organic resin, the MoS2/C composite particles were prepared through the solvent heat method by chooses ammonium molybdate as a source of molybdenum, thioacetamide as sulfur source, and the activated carbon as carbon source at the same time. The MoS2/C composite particles were then used as fillersto modify the bismaleimide BMI (BMI), and the MoS2/C/BMI composites were finally prepared.The influence of MoS2/C composite particle content on the mechanical properties, tribological properties, and the heat resistance, and the humidity resistanceof the MoS2/C/BMI composites were also researched.The results showed that the MoS2/C particles were smaller and more uniform than the traditional MoS 2 nanoparticles, while the properties of MoS2/C/BMI composites were the best when the content of MoS2/C composite particles was 6.0 wt%.
