ÏÈÒëÒ»¶Î°É: Polyimide, a new polymer materials of high perfomance, has been widely used as special engineering materials in various fields such as aeronautics and space, nanotech, liquid crystal, separating membrane, and laser, etc. In recent years, research & development as well as application of polyimides have been regarded as one of the most promising engineering plastics. Furthermore, synthetic polyimides have also been applied in coatings. Good solubility is necessary for the synthetic PAE/PSPI as oligmers of UV solidification, which will set a base on the subsequent UV solidification coatings. To improve PAE solubility, flexible groups and side groups will be introduced to destroy the order and symmetry of molecular chain, further decreasing intermolecular interaction. |
