METHOD OF MAKING MICROPOROUS FILTER MEMBRANE |
摘要 |
<p>A method is described for making a monolithic polymeric filter membrane having a filter layer that includes micron-scale precision-shaped pores and a support layer that includes a precision-shaped porous support structure for the filter layer. The method comprises forming the filter layer by removing selected material from one side of a polymeric film to define the micron-scale precision-shaped pores of the filter layer; and forming the support layer by removing selected material from the other side of said film to define the precision-shaped porous support structure. The pores of the filter layer communicate with the porous support structure to allow for the passage of filtrate therethrough.</p> |
