HYDROPHILIC POROUS MEMBRANE, METHOD OF PRODUCING THE HYDROPHILIC POROUS MEMBRANE, MEDICAL ANTI-ADHESION MEMBRANE, AND SUBSTRATE FOR CELL PROLIFERATION

摘要

PROBLEM TO BE SOLVED: To provide a hydrophilic porous membrane having biodegradability and having excellent adhesiveness to a wet surface.

SOLUTION: The hydrophilic porous membrane contains a multi-block copolymer of a polylactic acid and polycaprolactone and has voids formed by an alkaline hydrolysis treatment. Alternatively, the hydrophilic porous membrane contains the multi-block copolymer of the polylactic acid and the polycaprolactone and has voids that communicate with a membrane back surface from a membrane front surface.
