Preparation of hydrophilic HDPE porous membranes via thermally induced phase separation by blending of amphiphilic PE-b-PEG copolymer

▶ Fabrication of anti-fouling HDPE membranes by TIPS from blending it with PE-b-PEG. ▶ The segregation of PEG segments takes place at the HDPE/PE-b-PEG membrane surface. ▶ Explaining membrane's performance and morphology by droplet growth kinetics. ▶ Copolymer-enriched surface of blend membrane was shown to be stable in water.
