Plasma of Polymerizable Molecules

Plasma polymerization with easily polymerizable monomers, which carry multiple bounds, can be used for modifying the membrane surfaces by the deposition of new, thin polymer layers with thicknesses from several nanometers to one micrometer. 

Such layers are usually made of highly cross-linked material and show good adhesion to the substrate. Examples of such membrane surface treatment are plasma polymerization of allyl alcohol and allyl amine (Gancarz et al. 2002, 2003). It was shown that the membranes modified with allyl amine do not foul as intensively during UF of the BSA solutions compared with the unmodified membranes. Similar behavior was also shown for membranes modified by the deposition of plasma-polymerized n-butylamine however, in this case, the modified layer deposited on the manbrane surface was not as enriched in amines as the polymer formed from aUyl amine (Gancarz et al. 2002).
