Document Type and Number:
WIPO Patent Application WO/2014/092485
Kind Code:
A1
Abstract:
The present invention relates to a coating agent composition having excellent heat resistance and drying processability, which is obtained by dissolving a highly heat-resistant polyimide in a low-boiling point solvent. Specifically, the present invention relates to a coating agent composition obtained by dissolving a highly heat-resistant polyimide in a low-boiling point solvent which includes water and alcohol and has a boiling point of 100̊C or less. Also, the present invention relates to a separation membrane in which heat resistance is improved by coating one side or both sides of a polyolefin-based base film with the coating agent composition containing polyimide, and an electrochemical battery having enhanced thermal stability using the separation membrane.
