摘要
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。
CoS nanoparticles were successfully prepared by the reaction of acetate solution and H2S gas in epoxy matrix. By emplo- ying differential scanning calorimetry （DSC） , under non-isothermal condition, the kinetic analysis of the cure reaction was performed using two classic models ： Kissinger and Flynn-Wall-Ozawa. Furthermore, the corrective properties of CoS/epoxy nanocomposites were studied by XRD, TEM, mechanical test and PL. The investigations showed that the mechanical properties of CoS/epoxy were obviously enhanced in the presence of MS nanoparticles. The possible mechanism of preparation of CoS/epoxy composites was discussed.
