NANOFIBER FILTER FOR EXCELLENT HEAT-RESISTING PROPERTY AND ITS MANUFACTURING METHOD WITH POLYVINYLIDENE FLUORIDE ELECTROSPINNING ON CELLULOSE SUBSTRATE AND CERAMIC COATING

摘要

The present invention relates to a heat resistance nanofiber filter manufactured by forming a ceramic coating film on a polyvinylidene fluoride nanofiber nonvwoven fabric having polyvinylidene fluoride (PVDF) electrospinned on a cellulose base material for improving low heat resistance of an existing filter. The manufactured heat resistance nanofiber filter is characterized by not only having excellent heat resistance by including a polyvinylidene fluoride which is a heat resistance polymer and a ceramic coating film, but also having excellent filter efficiency.
