Abstract:
The present invention relates to a method for manufacturing a beta-phase PVDF film using spray coating and, more specifically, to a method for manufacturing a beta-phase PVDF film comprising the steps of: dissolving PVDF in a solvent (step 1); manufacturing the PVDF film by spray coating the PVDF-dissolved solution in the step 1 on a substrate (step 2); and peeling off the PVDF film manufactured in the step 2 from the substrate (step 3). The method for manufacturing the beta-phase PVDF film using spray coating according to the present invention can manufacture the beta-phase PVDF film through an extremely simplified process compared with a conventional stretching and pulling process, and especially has an effect of easily manufacturing a thin beta-phase PVDF film by not carrying out the stretching process.
