Porous polytetrafluoroethylene membrane having a macro-textured surface and method of making the same |
| abstract |
Compositions and methods directed to the production of single layer, highly porous, free-standing polytetrafluoroethylene (PTFE) membranes having macro-textured surfaces are provided. The macro-textured surfaces are due to the presence of macroscopic nodal aggregates within the membrane that are connected by fibrils The membranes have high porosity, high airflow, and a bulk density less than 1.0 g/cm3. Articles comprising the porous, single layer PTFE membranes are also provided. |
