Answer added in Nanocomposites8 Which processing parameters affect the properties of organically modified nanoclay/epoxy nanocomposites in direct mixing/ultrasonication processes?By Bikramjit Sharma · Thapar UniversityRashmi Devi · Tezpur UniversityIn order to develop nanocomposite systems with tailored properties, it is necessary to incorporate the reinforcing filler into the polymer matrix thro... [more]In order to develop nanocomposite systems with tailored properties, it is necessary to incorporate the reinforcing filler into the polymer matrix through an appropriate method maintaining adequate processing parameters. The required parameters are basically the size distribution of clay, dispersion of clay nanopartices in polymer matrix, amount and choice of modifying agent used as a interlayer surfactant for pristine clay to attain good compatibility as well as enhaced interfacial effect with the polymer, duration of soaking in swelling agent, and ultrasonication conditions,mechanical shear , temperature profiles, design, additives such as anti-oxidant, cooling rates etc.Following

R. R. Devi, T. K. Maji[show abstract] [hide abstract]
ABSTRACT: Simul wood (Salmalia malabarica) was chemically modified by treatment with styrene–acrylonitrile copolymer (SAN), glycidyl methacrylate (GMA), and organically modified nanoclay. The physical properties of wood polymer composites (WPC) were improved due to the addition of GMA and nanoclay. XRD analysis indicated a decrease in crystallinity in WPC. FTIR study confirmed the presence of clay in WPC. The presence of clay in cell lumen and cell wall was evidenced by SEM study. WPC containing lower percentage of clay showed better thermal stability compared to WPC loaded with higher percentage of clay.Wood Science and Technology 04/2012; 46(1):299-315. · 1.73 Impact Factor -

Article: Preparation and characterization of wood/styrene‐acrylonitrile copolymer/MMT nanocomposite
R. R. Devi, T. K. Maji[show abstract] [hide abstract]
ABSTRACT: Wood polymer nanocomposite (WPNC) was prepared by impregnating Simul (Salmalia malabarica) wood with styrene-acrylonitrile copolymer (SAN), glycidyl methacrylate(GMA), and a reactive polymerizable surfactant modified montmorillonite (MMT). The physical and mechanical properties of WPNC were investigated by using XRD, tensile tester, SEM, and FTIR. The polymer loading, dimensional stability, water uptake, mechanical property, and thermal stability were found to improve due to inclusion of MMT. SEM micrographs showed the presence of polymer and MMT into cell wall and cell lumen. FTIR analysis confirmed the presence of MMT and SAN in WPNC. © 2011 Wiley Periodicals, Inc.
