POROUS FILM HAVING REACTIVE POLYMER LAYER THEREON FOR USE IN BATTERY SEPARATOR, AND USE OF THE POROUS FILM |
摘要 |
<p>The present invention relates to a reactive polymer layer-supported porous film for battery separator, including: a porous film substrate; and a reactive polymer layer supported on the porous film substrate, the reactive polymer layer having a thickness of 2 µm or less and being obtained by a crosslinking reaction between a polyfunctional isocyanate and a crosslinkable polymer having both a reactive group capable of reacting with an isocyanate group and a cationically polymerizable functional group in the molecule thereof, in which the reactive polymer layer has a plurality of through-holes having an average pore diameter of 5 µm or less.</p> |
