摘要: Hydrophilicity of hydrophilic polymers, in the form of heat-crosslinked cings on porous membranes, is increased by exposure to an oxygen plasma, preferably for about 60 seconds. The plasma is generated at an oxygen gas pressure of about 1.5 Torrs in a chamber subjected to radio frequency electromagnetic radiation with a power of 25-100 watts. Such highly hydrophilic membranes have increased efficiency and durability when used as ultrafiltration membranes for separating hydrophobic and hydrophilic materials, such as smoke-air and oil-water mixtures.
