Abstract
The present disclosure provides a porous polymer membrane having a covalent network structure and a method for producing the same. The method includes: polymerizing a first monomer having four first functional groups oriented in a tetrahedral arrangement with a second monomer having at least two second functional groups to prepare porous organic framework nanoparticles; mixing the solution of the porous organic framework nanoparticles with a polymer; and applying the mixed solution to a substrate, followed by heating to form a polymer matrix containing the nanoparticles. According to the method, a polymer membrane with excellent chemical stability, heat resistance, durability and permeability can be produced through simple processes. Advantageously, the porous structure of the polymer membrane can be easily modified depending on intended applications of the polymer membrane.
