PROCESS FOR THE FABRICATION OF A WATER FILTER |
| 摘要 |
The invention relates to a method for the manufacture of a layered membrane construction comprising a) providing a solution comprising a mixture of a polymer A and a polymer B in a weight ratio A/B between 50/50 and 95/05, polymer A having a melting temperature TmA and a polymer B having a melting temperature TmB wherein TmB is below TmA by at least 40° C.; b) applying the solution provided in step a) on a first carrier substrate to form a nanofiber layer on said substrate; c) consolidating the nanofiber layer formed on the substrate by thermal bonding at a temperature between TmB and TmA by means of a temperature and/or pressure cycle thus obtaining the membrane. |
