摘要
A novel procedure to synthesize in situ clay/nylon‐6 composite suspension was explored via anionic solution polymerization. The suspension was efficiently blended with water‐based epoxy resin using mechanical stirrer at room temperature. Hence, a 3‐component coating system was obtained consisting of nano‐clay, nylon‐6 and epoxy resin. Large number of coatings and films were prepared with variation in clay and nylon‐6 loading. Concentration of clay was found to have profound effect on crystallinity of nylon‐6, thereby affecting the overall properties of clay/nylon/epoxy composite. All the films were characterized for thermal and dynamic mechanical behavior using differential scanning calorimeter (DSC) and dynamic mechanical analysis (DMA). Lower amount of clay was found to increase the crystallinity of nylon‐6 which in turn increased the plasticization of epoxy resin indicated by reduction in T g . A multiphase morphology with distinct amorphous and crystalline zones was observed under scanning electron microscopy (SEM). A remarkable symmetrical morphology with branched dendritic crystal structure was observed for few of the clay/nylon/epoxy system. POLYM.
