Supercritical carbon dioxide-induced epitaxy on the surface of nylon1212 substrate
In this study we focus on the influence of the absorbed supercritical (SC) CO2 on the surface aggregation structure of the substrate polymer, nylon 1212. Both virgin and treated nylon 1212 were measured or observed with wide-angle X-ray diffraction (WAXD), micropolariscope and SEM. A novel phenomenon, SC CO2-induced epitaxy (crystalline overgrowth) was discovered and the mechanism is deduced.
