제목 Surface and Thermo-mechanical Properties of Polyimide Hybrid Films
초록 In FCCL (flexible copper clad laminate) preparation process, the interfacial relationship between polyimide film and copper foil is very important. Specially, the relationship of their discrepancy of CTE (coefficient of thermal expansion) and adhesive property between two faces are the serious problem in process FCCL. In this study, we prepared polyimide hybrid film via sol-gel process, inorganic material dispersed on polyimide matrix within nanoscale, and so roughness made on film surface (Figure1). It brought to improve adhesion property that unevenness rose on surface of film. Also, mechanical properties improve additionally.
In result, tensile strength improved about 30%, and elongation improved 2.4 times as increase content of TMOS. We ascertained formation of SiO2 by FT-IR spectrum, quantity of SiO2 in matrix estimated by TGA thermogram. Surface roughness of hybrid film increased as increased content of TMOS. We confirmed that silica particle uniformly dispersed in surface of hybrid film by SEM and AFM photography.
