Abstract

The present invention relates to a composite membrane. The composite membrane includes: an elastic polymer substrate having a first surface processed by a surface modification; and a thermosensitive conductive layer formed on the first surface by performing a co-polymerization process, allowing an electrical current to pass through, and altering a hydrophilicity of a membrane surface in response to a change of a temperature.
