Summary: | PURPOSE: A porous film coated with a biopolymer is provided to improve an environment friendliness, a heat resistance, and an intensity, and to perform a stability and an excellent zygosity with an electrode when being used for a separation film for a secondary battery. CONSTITUTION: A porous film comprises a catechol group in a surface, an inside, and all by being coated with a polycatechol group polymer. The porous film comprises 0.1-20 g/m^2 of a coating weight of the polycatechol group polymer. The polycatechol group polymer is selected from a group consisting of polydopamine, polyepinephrine, polynorepinephrine, and a mixture. Moreover, a separation film for a secondary battery comprises the porous film. |
