Pvdf is a widely used membrane material due to its properties such as high

mechanical strength, thermal stability, anti-ultraviolet radiation, smooth surface and

low protein adsorption. However, the hydrophobicity of pvdf causes membrane

fouling and limits the application in wastewater treatment. Thus is it important to

improve the hydrophilicity of the material surface. Surface coating with hydrophilic

materials such as polyethylene glycol (PE! is used to modify the surface propertyof pvdf due to its anti- fouling properties and a high level of hydrophilicity, thus

improves its membrane "u# performance.

$n this e#periment, the permeable properties of pvdf membrane are determined by

coating with PE polymers. The membrane porosity is used to determine membrane

water "u# performance.
