제목 Characterization and Thermo-Mechanical Properties of Polyimide Films Prepared from 4-Components Monomer
초록 Polyimide film has been used as FPCB (flexible printed circuit board), TAB (tape automated bonding), electric wire insulated clothing materials and tape, because it had high heat- and cold-resistance and high performance electric properties1,2. The CTE (coefficient of thermal expansion) relationship of polyimide film and copper foil is one of most important factor in preparation for FCCL (flexible copper clad laminate) constituting FPCB. If discrepancy in CTE value of film and copper foil was high, it showed that CCL was curled. Hence, in this study, we polymerized polyamic acid from 4-component monomer, in order to CTE value decrease in PMDA-ODA system, and prepared polyimide films. Anhydride and diamine mole ratio controlled by BTDA/ PMDA and PDA/ODA, respectively. The CTE value of resulting materials showed that more depend on PDA/ODA mole ratio than that of BTDA/PMDA (Figure 1). As PDA content increased, elastic modulus and tensile strength increased, too (Figure 2).
