In addition, the applications of modified PP membrane are presented as well. Polypropylene (PP) is one of the most important polymers for microporous membrane due to its high void volume, well-controlled porosity, high thermal and chemical stability, and low cost. However, the hydrophobicity of PP becomes a limitation to broaden its applications. Furthermore, membrane fouling occurs more seriously on hydrophobic membranes than hydrophilic ones.

Jan 20, 2014 · Hydrophilic polypropylene membrane GHP-200, 0.2 μm were from Pall Corporation (Mississauga, ON, Canada); micro cover glasses 25 × 25 mm 2 and plain glass microscope slides 75 × 25 mm 2 were from Aijiren Tech Scientific (Ottawa, ON, Canada). All solutions were prepared with 18.2 MΩ·cm water from Barnstead NanoPure Diamond (18 MΩ) water
Here, the polypropylene membrane was tested by O 2 plasma to emphasize that the contact angle nonlinearly decreases with the treatment time. The XPS surface sensitive technique was applied to confirm the drastic skin change of the oxygen content showing that membrane becomes super hydrophilic due to the significant O 2 implant.

Hydrophilic membranes such as regenerated CA are less susceptible to fouling than hydrophobic membranes such as PVDF, PS, PES and PP. The influence of the membrane material on the fouling of membranes shows that the flux of hydrophilic membranes is only marginally reduced, whereas the flux reduction of hydrophobic membranes is significant [70
Differences between hydrophilic membranes and hydrophobic membranes. A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.
