Hydrophobic polymeric membrane composites
A composite porous membrane is formed from a porous polymeric substrate having its entire surface modified with a cross-linked polymer which results in a hydrophobic and oleophobic surface. The composite membrane retains substantially all of its other original properties. The cross-linked polymer is...

| description | A composite porous membrane is formed from a porous polymeric substrate having its entire surface modified with a cross-linked polymer which results in a hydrophobic and oleophobic surface. The composite membrane retains substantially all of its other original properties. The cross-linked polymer is formed in situ on the polymeric substrate from a reactant system comprising an ethylenically unsaturated monomer having at least one fluoroalkyl group, a cross-linker, and, if needed, a polymerization initiator, dissolved in a nonpolar and or weakly polar solvent system. The membrane substrate saturated with the reactant system is exposed to a suitable energy source to effect polymerization and cross linking of the monomer. |
