Title:
MANUFACTURING METHOD OF HYBRID OSMOTIC POWER GENERATION FILM CONTAINING BLOCK COPOLYMER FILM AND FUNCTIONAL POROUS FILM
Document Type and Number:
WIPO Patent Application WO/2018/214723
Kind Code:
A1
Abstract:
Provided are a manufacturing method of a hybrid osmotic power generation film containing a block copolymer film and a functional porous film, and a film manufactured by using the same. The manufacturing method comprises the following steps: 1) using a sacrificial layer to block through-channels of a functional porous film; 2) dissolving a block copolymer in a solvent to form a solution; 3) arranging the formed solution over the pre-processed functional porous film, such that the block copolymer forms a film on the pre-processed functional porous film; 4) using a selective solvent to dissolve the sacrificial layer; and 5) performing annealing at a saturated atmosphere of the solvent in step 2), such that the block copolymer has vertical through-channels.
