FILTER INCLUDING POLYVINYLIDENE FLUORIDE (PVDF) NANOFIBER HAVING DIFFERENT DIAMETER AND INCLUDING LOW MELTING POINT POLYMERIC ADHESIVE LAYER AND PRODUCTION METHOD THEREOF

摘要

The present invention relates to a filter including a nanofiber and a production method thereof. More specifically, the present invention relates to a nanofibrous filter. To this end, laminated on a base material are a first polyvinylidene fluoride (PVDF) nanofiber layer having the fiber diameter of 150-300 nm, and a second polyvinylidene fluoride nanofiber layer having the fiber diameter of 100-150 nm. In addition, gaps between the base material and the nanofiber layer and also between the nanofiber layers are bonded by an adhesion layer formed by spinning a low melting point polymer. According to the present invention, the nanofibrous filter prevents secession, can be produced consecutively, and ensures efficient processes and mass-production, thereby being economically feasible.;COPYRIGHT KIPO 2016
