POROUS SHEETS

Abstract:

A method of preparing a porous sheet includes mixing a matrix material dispersion including a matrix material dispersed in a first dispersion medium with a microorganism dispersion including microorganisms in a second dispersion medium, to form a mixture. The first and the second dispersion media are removed from the mixture to form a matrix sheet, and the microorganisms are decomposed from the matrix sheet to form the porous sheet.
