| titleOfInvention | Preparing method of porous pvdf nanofaiber and porous pvdf nanofaiber prepared by the method |
| abstract | The present invention relates to a method for producing porous PVDF nanofibers, comprising mixing a PVDF and PEO together in a solvent to form a raw material; A molding step of molding the raw material into a nanofiber shape; And a pore forming step of selectively removing only PEO from the formed nanofibers to form a porous structure. The manufacturing method of the present invention has the effect of manufacturing PVDF nanofibers having a porous structure by removing PEO after forming into a nanofiber form. Further, the manufacturing method of the present invention has the effect of forming more pores by the vapor pressure difference and the liquid-liquid phase separation by mixing water together with the solvent dissolving the PVDF. Furthermore, since the porous PVDF nanofiber according to the present invention has many pores and has a large specific surface area and a large contact angle with water, the porous PVDF nanofiber exhibits a very suitable property as a pre-filter used in the previous stage of the filter for removing oil- It is possible to increase the lifetime of the expensive filter. |
