PREPARATION METHOD OF POLYVINYLIDENE FLUORIDE NANOPARTICLE AND POLYVINYLIDENE FLUORIDE NANOPARTICLE PREPARED THEREBY

摘要

The present invention relates to a polyvinylidene fluoride (PVDF) nanoparticle preparation method. The method includes the steps of: preparing a mixed solution by mixing a radical initiator, a surfactant, and distilled water in an reaction vessel (step 1); and making the reaction vessel storing the mixed solution prepared in the step 1 reach the reaction temperature of 60-90°C and the reaction pressure of 10-100 bar and stirring the mixed solution at the speed of 100-1,000 rpm, and adding vinylidene fluoride (VDF) at the rate of 0.5-2 g/min to initiate the reaction thereof (step 2). According to the present invention, the PVDF nanoparticle preparation method can adjust the molecular weight of the PVDF nanoparticles by adjusting the reaction conditions. Accordingly, the PVDF nanoparticles prepared by the method can have the properties satisfying the requirements of various fields.;COPYRIGHT KIPO 2015
