以醋酸钴和硫化氢气体为反应原料,在环氧树脂体系中,成功地制备了硫化钴纳米颗粒。在差示扫描量热法(DSC)的非等温条件下,采用Kissinger和Flynn-Wall-Ozawa两种经典模式对复合材料的固化反应动力学进行研究。此外,还通过XRD、TEM、力学性能、PL等表征手段对复合材料的相关性能进行了测试。研究结果显示,硫化钴颗粒分散均匀,并且其复合材料的力学性能得到明显提高。同时,还对硫化钴/环氧树脂复合材料的形成的可能机制进行讨论。 Cobalt sulfide and hydrogen sulfide gas as raw materials in the epoxy resin system, the successful preparation of cobalt sulfide nanoparticles. Under non-isothermal conditions of differential scanning calorimetry (DSC), two typical modes, Kissinger and Flynn-Wall-Ozawa, were used to study the curing reaction kinetics of composites. In addition, the relative properties of the composites were also tested by XRD, TEM, mechanical properties, PL and other characterization methods. The results show that cobalt sulfide particles dispersed evenly, and the mechanical properties of the composite material has been significantly improved. At the same time, the possible mechanism of the formation of cobalt sulfide / epoxy composites is also discussed.
