Abstract
The present invention relates to: an ion exchange membrane containing, in a channel, an inorganic particle, substituted with an organic compound including SO4− group; and a method for manufacturing the ion exchange membrane. The ion exchange membrane according to the present invention can provide excellent physical properties while also maintaining ion conductivity.
Claims10
An ion exchange membrane containing, in an ion channel, inorganic particles including phenyl groups substituted with SO4− ions.
A method for manufacturing an ion exchange membrane, comprising the steps of:
- preparing a base membrane from a porous substrate;
- dipping the base membrane into a mixture containing one or more benzene compounds substituted with a hydroxy group, an inorganic particle precursor and methanol to introduce inorganic particles to the base membrane;
- and
- dipping the base membrane to which the inorganic particles are introduced into a sulfuric acid solution to introduce functional groups thereto.
