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]  in Industrial & 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.

Effect of nanoparticles on flammability, UV resistance, biodegradability, and chemical resistance of wood polymer nanocomposite / Biplab K. Deka in Industrial & engineering chemistry research, Vol. 51 N° 37 (Septembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 37 (Septembre 2012) . - pp. 11881–11891 Titre : Effect of nanoparticles on flammability, UV resistance, biodegradability, and chemical resistance of wood polymer nanocomposite Type de document : texte imprimé Auteurs : Biplab K. Deka, Auteur ; Manabendra Mandal, Auteur ; Tarun K. Maji, Auteur Année de publication : 2012 Article en page(s) : pp. 11881–11891 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Nanoparticles  Polymer Résumé : Wood polymer nanocomposite (WPNC) was developed by using high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polyvinyl chloride (PVC), wood flour (WF), polyethylene-co-glycidyl methacrylate (PE-co-GMA), and different nanoparticles viz. nanoclay, SiO2, and ZnO. The distribution of nanoparticles was examined by X-ray diffraction (XRD) study. The change in surface morphology due to the addition of compatibilizer and nanoparticles was studied by scanning electron microscopy (SEM). The surface modification of nanoparticles by organic surfactant and their interaction with polymer and wood was studied by Fourier transform infrared spectroscopy (FTIR). The UV resistance property was improved after the incorporation of clay, SiO2, and ZnO. Bacterial degradation of WPC was found to increase linearly with the incorporation of clay and nanoparticles. The degraded samples showed lower mechanical properties. Flame retarding property, chemical resistance, and water vapor resistance were found maximum in WPC loaded with 3 phr each of clay, SiO2, and ZnO.
