Abstract: In order to promote technological progress in the field of materials and promote the development of related industries, research has been conducted on the preparation and thermal/mechanical properties of nanocomposites. Using polycarbonate (PC) nanocomposites as the base material and silane coupling agent KH570 as the organic modifier, the surface of MoS₂ nanosheets peeled off by hydrazine hydrate pretreatment method was modified using organic modifiers. Then, the modified MoS₂ nanosheets were used as fillers to prepare PC MoS₂ nanocomposites, and infrared spectroscopy, thermogravimetric analysis, and tensile performance testing were conducted to achieve thermal and mechanical property analysis. After analysis, it was found that the modified MoS₂ nanosheets formed good dispersion in PC nanocomposites. The prepared PC/KH570-MoS₂ nanocomposites exhibited good thermal and mechanical properties, as well as good thermal stability and tensile properties. Moreover, when the modified MoS₂ content was 3 wt. % at this time, its tensile strength, fracture elongation, and elastic modulus can reach 16.75 Mpa, 12.686%, and 5,741 Mpa, respectively. After repeated testing, the standard deviation and coefficient of variation of the results were small, with maximum values of 0.02 and 0.12, respectively, indicating the reliability of the obtained results.

Keywords: preparation of nanocomposites; MoS₂ nanosheets; PC nanocomposites; thermal properties; mechanical properties.
