This paper reviews recent developments of the hydrophilic modification of porous polymer membranes by the low temperature plasma method

with46references referred.After a brief description of the plasma principle

three plasma treatment techniques

plasma surface treatment technique by some unreactive and reactive gas

plasma deposition polymerization by saturated and unsaturated monomers

such as alkyl alcohol

alkyl amine

allyl alcohol

and allyl amine

and plasma induced graft polymerization by the alkene monomer with a polar group

are discussed applying in the membrane surface hydrophilic modification.Their effects on the chemistry structure and morphology structure of both the membrane surface and pore wall

on the degree and permanence of the hydrophilicity

and on the improvement of water flux and the protein antifouling of the modified membrane

are summarized.
