| titleOfInvention | Preparation of novel cyclodextrin thermally induced micropore polyimide gas separation membrane |
| abstract | The invention discloses preparation of a novel cyclodextrin thermally induced micropore polyimide gas separation membrane. A polyimide material containing certain cyclodextrin is synthesized based on a clathrate compound formed by cyclodextrin and an aromatic diamine monomer; the following purposes are achieved by utilizing a principle of lower cyclodextrin thermolysis temperature and controlling the temperature and the heat treatment time in a nitrogen atmosphere: 1) the size of a new pore in polyimide after thermal rearrangement is intended to be controlled by introducing cyclodextrin monomers in different sizes, and 2) the porosity of the new pore after the thermal rearrangement is intended to be controlled by different thermolysis temperatures and different thermolysis quantities of the cyclodextrin monomers; a series of pore diameter controllable thermal rearrangement polyimide membranes with high gas permeability, high separation property and apparent whole are prepared by taking the gas permeation separation property as a feedback basis; finally the polyimide membrane suitable for separation of current common acid gas such as CO2 and H2S, separation of O2/N2, separation and recovery of organic vapor, and separation of H2 is obtained. Moreover, the problems of smaller gas permeability, higher membrane component cost and the like of a polyimide membrane material in a gas separation application are solved to a certain extent. |
