Abstract

A series of high molecular weight polyimide precursors with different intrinsic viscosity were synthesized via changing the ratio of dianhydrides (BTDA/BPDA) acted with diamine monomer at the low temperature polycondensation. The as-obtained polyamic acids were then thermal imidized to form polyimide (PI). The structures and properties of polyimides were studied by using IR, UV-visible, TG, mechanical test and contact angle (CA) measurement. The results show that the properties of the polyimides vary with the different ratio of BTDA/BPDA components. A higher ratio of BTDA component in the polyimide is related to a good UV-visible transmission. In reverse, the polyimide with higher ratio of BPDA exhibits better thermal stability as well as higher tensile strength and elastic modulus. Furthermore, all of the polyimide films possess excellent hydrophobic properties.
