Transparent and colorless heat resistant films have more importance in the field of next generation flexible display industry. The most important factor among requirements for flexible substrate is the control of dimensional stability during thermal process. To decrease the CTE(coefficient of thermal expansion), several methods such as nanohybridization, introduction of IPN, or preparation of transparent FRP(Fiber reinforced plastics) can be adopted. In this research, we controlled the refractive index(RI) by introduction of nanofillers, and elucidated their behavior qualitatively. And then, we prepared glass web reinforced films based on colorless polyimide. Their optical and physical properties were explained in terms of RI differences. |
