| 제목 | Water sorption and diffusion behaviors in the composite films of poly(ether imide) and bismaleimide |
| 초록 | The effect of a crosslinkable imide moiety, bismaleimide (BMI), on the water sorption properties of the polyether imide (PEI) was gravimetrically measured and interpreted together with chemical structure and morphological structure in composite films. The morphological structure of composite films were investigated by using a prism coupler and x-ray diffraction pattern, indicates that the in-plane orientation and intermolecular packing order increased as the content of BMI in composite films increases. It was found that the water sorption behaviors showed dependence on the morphological change originated from the addition of BMI to PEI. The composite film with relatively high content of BMI exhibited relatively high degree of in-plane orientation and small mean intermolecular distance, which resulted in decrease in diffusion rate and water sorption and increase in activation energy in composite films. This work was supported by the Ministry of Science and Technology of Korea throgh the National Research Laboratory Program and Center for Electronic Packaging Materials of Korea Science and Engineering foundation. |
