SEPARATOR FILM COATING MATERIAL USING A POLYMER DERIVED FROM MUSSELS AND METHOD FOR MANUFACTURING SAME, AND MATERIAL FOR PREVENTING HEAT SHRINKAGE AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a method for manufacturing a hydrophilic porous separator film using a process of coating a polymer derived from mussels, and to an electrochemical cell including the hydrophilic porous separator film. The porous separator film coated with polydopamine according to the present invention is eco-friendly, and the process for manufacturing an economical manufacturing process. Also, since the coated polymer effectively provides hydrophilicity without damaging the pores of the separator film, the porous separator film may improve usability with an electrolyte and the impregnation performance of the electrolyte through an improved wetting ability so as to produce a high-output cell and a high-capacity cell.
