The fluoro-containing copolymer film of surface modification and production method thereof |
| abstract |
A kind of method for manufacturing filtration article, the method includes providing porous fluoropolymer polymeric film (M), and at least some of power that applies of film the first side surface with modified first side surface.The power applied can have and the component of the first side surface non-vertical direction, and can apply by reversely rotating roller (50).The porosity on the surface that surface modification can improve the density on the surface being modified and/or reduction is modified.Thus improve the granule reserve capability on the whole surface being modified, maintain the permeability of whole membrane volume. |
