Fuentes, S.; Ayala, M. V.; Benavente Espinosa, Eglantina; González Moraga, Guillermo (TAYLOR & FRANCIS LTD, 2010)A series of new Chitosan=poly(mercaptopropysiloxane) hybrid films were obtained by blending mercaptopropylsiloxane oligomers (pMPS) with chitosan (CHI). The MPS oligomers were prepared by sol-gel using as precursor ...
