Abstract:
A porous membrane with a molecular weight cut-off (MWCO) greater than about 10 kDa, and a coating on at least a portion of a major surface of the porous membrane. The coating includes a star polymer having a hydrophobic core and hydrophilic arms, wherein the hydrophobic core contacts the porous membrane.
