Artigo IPEN-doc 24184 Effect of gamma radiation on polyvinylpyrrolidone hydrogels2017 - OLIVEIRA, M.J.A.; VASQUEZ, P.A.S.; ALCANTARA, M.T.S.; MUNHOZ, M.M.L.; LUGAO, A.B.Polyvinylpyrrolidone (PVP) hydrogels have been investigated as drug delivery matrices for the treatment of wounds, such as cutaneous leishmaniasis, and matrices with silver nanoparticles for chronic wounds and burns. The preparation of such hydrogels can occur by various cross-linking methods, such as gamma, chemical, physical, among others. The most feasible for wound dressings is gamma irradiation from cobalt-60, because gamma irradiation simultaneously promotes crosslinking and sterilization, leaving the wound dressing ready for use. The objective of this work was to investigate the effect on physico- chemical properties of gamma radiation on PVP hydrogel according to the radiation absorbed dose variation. The PVP hydrogels were irradiated with doses of 5, 15, 25, 35, 45, 55, 65, 75 and 95kGy at dose rate of 5 kGy/h and characterized by swelling, thermogravimetric and mechanical analysis. Results shown a favorable dose range window for processing of these hydrogels related to the application. The results showed that mechanical strength was affected at doses starting at 25 kGy.Artigo IPEN-doc 21103 Hydrogel de PVP/CMC e nanoparticulas de prata2015 - MUNHOZ, MARA M.L.; OLIVEIRA, MARIA J.A.; ALCANTARA, MARA T.S.; LINHARES, KAMILA P.; ROGERO, SIZUE O.; LUGAO, ADEMAR B.Artigo IPEN-doc 21098 Hidrogel polimérico com alginato e AgNP para tratar e absorver exudato de feridas2015 - LINHARES, KAMILA P.; OLIVEIRA, MARIA J.A.; ALCANTARA, MARA T.; MUNHOZ, MARA M.L.; LUGAO, ADEMAR B.Artigo IPEN-doc 12615 Estudo da reticulação da matriz de poli(vinil pirrolidona) (PVP) e carboximetil celulose (CMC) para a obtenção de hidrogeis utilizados em curativos2006 - ALCANTARA, M.T.S.; ABSY, E.; ROGERO, S.O.; LUGAO, A.B.Artigo IPEN-doc 12076 Propriedades mecanicas da blenda de poli(vinilpirrolidona)/carboximetil cellulose (PVP/CMC)2007 - ALCANTARA, MARA T.S.; AMARAL, RENATA H.; ROGERO, SIZUE O.; DITCHFIELD, CYNTHIA; TADINI, CARMEN C.; LUGAO, ADEMAR B.Artigo IPEN-doc 10629 Estudo da reticulacao induzida por radiacao ionizante de poli(vinil pirrolidona)(PVP)/carboximetil celulose (CMC)2005 - ALCANTARA, M.T.S.; CHIRINOS, H.; AMARAL, R.H.; ROGERO, S.O.; LUGAO, A.B.Artigo IPEN-doc 16137 Synthesis and characterization of hydrogels composed by different types of poly(vinyl alcohol)2010 - ALCANTARA, MARA T.S.; VARCA, GUSTAVO H.C.; AMARAL, RENATA H.; MATTOS, THAMIRES C.B.; RIELLA, HUMBERTO G.; LUGAO, ADEMAR B.Artigo IPEN-doc 15900 Hidrogeis superabsorventes a partir de poliacrilamida2010 - GUADAGNIN, H.C.; BRANT, A.J.C.; NAIME, N.; ALCANTARA, M.T.S.; PONCE, P.; LUGAO, A.B.Artigo IPEN-doc 15902 Estudo da reticulacao induzida por radiacao gama de misturas de poliacrilamida anionica e agua2010 - ALCANTARA, M.T.S.; BRANT, A.J.C.; NAIME, N.; GUADAGNIN, H.C.; PONCE, P.; LUGAO, A.B.Artigo IPEN-doc 15899 Obtencao e caracterizacao de hidrogeis a base de polivinil alcool de diferentes propriedades2010 - ALCANTARA, M.T.S.; VARCA, G.H.C.; GIANNINI, D.R.; RIELLA, H.G.; LUGAO, A.B.
