POROUS SEPARATION MEMBRANE FOR ELECTROCHEMICAL DEVICE, CONTAINING POROUS SUBSTRATE HAVING INVERSE OPAL STRUCTURE, AND PREPARATION METHOD THEREFOR |
摘要 |
The present disclosure provides a porous separator substrate with an inverse opal structure obtained by using an engineering plastic resin with high heat-resistance, and a manufacturing method thereof. In the method, a non-crosslinked polymer resin is used to form an opal structure and a crosslinked polymer resin is penetrated into the opal structure and an organic solvent is used to remove the polymer particles being used to form the opal structure, thereby manufacturing a porous substrate with an inverse opal structure. According to the present disclosure, a separator having good porosity and air permeability can be provided without the problems of heat-resistance decrease, pore closing and thickness decrease. |
