Membrane fouling remains an unavoidable major challenge for useful applications of nanofiltration membranes, increasing the overall energy requirements of the separation process and shortening the membrane lifetime. By introducing hydrophilic particles, hydrophilic polymers and amphiphilic copolymers to prepare a hydrophilic surface, the antifouling performance of ptfe hydrophilic filter membrane can be greatly improved. For hydrophobic membrane surfaces, this can be achieved by using fluoropolymers or silicone compounds with lower surface energy.
The filter assembly needs to be fully compatible with the chemical properties of the sample. The filter membrane contains wetting agents that may interfere with some applications. Some membrane filters may bind proteins or other large molecules, causing filter clogging or sample loss. Therefore, it is very important to understand the sample properties.
The membrane is hydrophobic and suitable for filtering gases. PTFE hydrophilic filter membrane has very good chemical resistance, which makes it very suitable for filtering solvents or other corrosive chemicals that other filter membranes cannot filter. Due to its hydrophobicity, Teflon membranes need to be pre-wetted with a solvent (ethanol) before filtering aqueous solutions.
