Effect of nano - ZnO on thermal, mechanical, UV stability, and other physical properties of wood polymer composites / Rashmi R. Devi in Industrial & engineering chemistry research, Vol. 51 N° 10 (Mars 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 10 (Mars 2012) . - pp. 3870–3880 Titre : Effect of nano - ZnO on thermal, mechanical, UV stability, and other physical properties of wood polymer composites Type de document : texte imprimé Auteurs : Rashmi R. Devi, Auteur ; Tarun K. Maji, Auteur Année de publication : 2012 Article en page(s) : pp. 3870–3880 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Physical properties Polymer composites Résumé : Wood polymer nanocomposite (WPNC) was prepared by impregnation of styrene-acrylonitrile copolymer (SAN) of 2:3 molar ratio, vinyl trichlorosilane (VTCS) modified ZnO nanoparticles and glycidyl methacrylate (GMA) as a cross-linking agent into cellular structure of wood. The surface modification of ZnO nanoparticles and the properties of the WPNC were investigated by XRD, FTIR, TGA, SEM and TEM. The mechanical properties including modulus of rupture (MOR), tensile strength and hardness, and multifunctional properties involving UV resistance, water resistance, dimensional stability and thermal stability were studied. The nano-ZnO particles dispersed uniformly in the polymer filled in the porous structure of wood, as evidenced by SEM-EDX and FTIR, respectively. TEM study showed the homogeneous dispersion of ZnO nanoparticles on the cell wall of wood with SAN polymer matrix.
