dc.description.abstractHydrophilic membranes based on PVP, containing 0.4 and 1% of carboxymethylcellulose staple fibers infused with calcium alginate were obtained and characterized in this study. The main proposal of this study is related to hydrogels based on PVP modified with carboxymethyl cellulose staple fibers infused with calcium alginate. This modified hydrogel is a hydrophilic membrane with better mechanical properties that can incorporate adequate drugs into the fibers for each lesion type. The hydrogels were obtained using ionizing radiation with an electron beam, at a dose of 25 kGy. The membrane's characterization was performed by tensile and physic-chemical tests (gel fraction and swelling). The results obtained showed that the membranes have higher mechanical strength, a higher swelling degree and a lower gel fraction. © (2011) Trans Tech Publications.
