Resumen
Composites of cellulose acetate and polysiloxane were prepared using 3-isocyanatepropyltriethoxysilane, as a coupling agent. The structure, the thermal and dynamic-mechanical behaviors, and the morphology of the obtained composites were investigated. The composites showed phase separation which was confirmed by the presence of siloxane micro- and nano-domains dispersed in the cellulose acetate matrix, with good interfacial adhesion between the phases. The results demonstrated that the incorporation of a polysiloxane phase on a cellulose acetate matrix caused a decrease in the glass transition temperature, storage modulus and hardness. The proposed methodology was seen to be convenient for the preparation of cellulose acetate/polysiloxane composites with useful properties. © 2013 Springer Science+Business Media Dordrecht. 20 6 2791 2802 Abbehausen, C., Formiga, A.L.B., Sabadini, E., Yoshida, I.V.P., A β-cyclodextrin/siloxane hybrid polymer: synthesis, characterization and inclusion complexes (2010) J Braz Chem Soc, 21, pp. 1867-1876 Amerio, E., Sangermano, M., Malucelli, G., Priola, A., Voit, B., Preparation and characterization of hybrid nanocomposite coatings by photopolymerization and sol-gel process (2005) Polymer, 46, pp. 11241-11246 Backman, A.C., Lindberg, K.A.H., Differences in wood material responses for radial and tangential direction as measured by dynamic mechanical thermal analysis (2001) J Mater Sci, 36, pp. 3777-3783 Bandyopadhyay, A., Bhowmick, A.K., De Sarkar, M., Synthesis and characterization of acrylic rubber/silica hybrid composites prepared by sol-gel technique (2004) J Appl Polym Sci, 93, pp. 2579-2589 Bellamy, L.J., (1966) The Infrared Spectra of Complex Molecules, , New York: Wiley Biermann, C.J., Chung, J.B., Narayan, R., Grafting of polystyrene onto cellulose acetate by nucleophilic displacement of mesylate groups using the polystyrylcarboxylate anion (1987) Macromolecules, 20, pp. 954-957 Botaro, V.R., Gandini, A., Modificação do acetato de celulose em meio homogêneo via reações de condensação com diferentes isocianatos (1998) Polim Cienc Tecnol, 8, pp. 64-71 Camino, G., Lomakin, S.M., Lazzari, M., Polydimethylsiloxane thermal degradation Part 1.
