The non-equilibrated, low-temperature plasma which is generated by glow discharge in gases is very suitable for the modification of polymer surfaces. Examples are plasma polymerization and plasma treatment In comparison with these plasma applications, plasma-induced graft copolymerization has attracted the attention of only very few researchers. 

The oxygen-free plasma-induced graft copolymerization with free radicals was extensively studied by Pales and his coworkers primarily in order to improve the dyeability of fibers, whereas very little is known about the graft copolymerization initiated by peroxide formed from oxygen The plasma-induced graft copolymerization via peroxide formation is briefly described below... 

Along with physical modification, chitosan is most commonly modified by a number of chemical techniques including traditional chemical modification techniques such as photochemical, enzymatic, radiation, and plasma-induced graft copolymerization. Figure 1.6 summarizes some of the commercially used modification techniques for surface modification of chitosans.
