The invention relates to a healable and recyclable polyimide polymer resin, a healing method and a recycling method thereof. The healable and recyclable polyimide polymer resin includes a chemical structural unit represented by Formula (I):
Formula (I).
In Formula (I), each symbol is defined in the description. In the repairing method, the healable and recyclable polyimide polymer resin is healed by a healing means at a healing temperature. In the recycling method, the healable and recyclable polyimide polymer resin is dissolved in a diethylenetriamine solution for further coating and baking to form a recycled polyimide film. Therefore, the healable and recyclable polyimide polymer resin is rigid, chemical-resistant, heat-resistant, healable and recyclable. |
