Because polycarbonate (PC) has high transparency, excellent heat resistance and flexural modulus, it is widely applied to the display of flexible devices, plastic electronics, and automobiles. However, in spite of its excellent physical properties, it exhibits poor surface hardness. Hard coating is essential to improve the surface hardness on PC surface. In this study, we prepared acrylate-based hard coating solution. In particular, we observe effect of glycidyl groups on acrylate hard coating layer. As a result, the surface hardness of hard coating was controlled by changing the ratio of glycidyl group. We confirmed the improvement of surface hardness on PC film due to ring-opening reaction of glycidyl groups. |
