Nanofiber filter for excellent heat-resisting property and its manufacturing method with Polyvinylidene fluoride electrospinning on cellulose substrate and ceramic coating

摘要

In order to improve the low heat resistance of the conventional filter, the present invention provides a heat-resistant polyvinylidene fluoride (PVDF) fabricated by providing a ceramic coating film on a polyvinylidene fluoride nanofiber nonwoven fabric obtained by electrospinning polyvinylidene fluoride The present invention relates to a nanofiber filter. The manufactured heat resistant nanofiber filter is characterized by being excellent in heat resistance and also having excellent filter efficiency because it comprises polyvinylidene fluoride which is a heat resistant polymer and a ceramic coating film.
