| 摘要 |
The present invention relates to a filter including polyvinylidene fluoride nanofibers and bicomponent substrates, and to a manufacturing method thereof. The present invention is to provide a filter in which polyvinylidene fluoride nanofiber non-woven fabrics are arranged in layers by electrospinning a solution in which high melting point polyvinylidene fluoride and low melting point polyvinylidene fluoride are mixed on both sides of a substrate in which a first bicomponent substrate, a polyethylene terephthalate substrate, and a second bicomponent substrate are arranged in layers; and a manufacturing method thereof. According to the present invention, the low melting point polyvinylidene fluoride plays a role as an adhesive between a substrate and nanofibers in a thermosetting process of the filter, thereby preventing that the nanofiber non-woven fabric is separated from the substrate. |
