“…The research concerning polymer nanocomposites based on organolayered silicates [1][2][3][4][5][6] highlighted the interest of such clays not only for increasing the stiffness [4] of these materials, but also for enhancing other properties of the polymers such as thermal [5,[7][8][9], flame retardancy [5,10] or gas barrier resistance properties [11,12].…”

Exfoliated nanocomposites are prepared by dispersion of poly(ε-caprolactone) (PCL) grafted montmorillonite nanohybrids used as masterbatches in poly(styrene-co-acrylonitrile) (SAN). The PCL-grafted clay nanohybrids with high inorganic content are synthesized by in situ intercalative ring-opening polymerization of ε-caprolactone between silicate layers organomodified by alkylammonium cations bearing two hydroxyl functions. The polymerization is initiated by tin alcoholate species derived from the exchange reaction of tin(II) bis(2-ethylhexanoate) with the hydroxyl groups borne by the ammonium cations that organomodified the clay. These highly filled PCL nanocomposites (25 wt% in inorganics) are dispersed as masterbatches in commercial poly(styrene-co-acrylonitrile) by melt blending. SAN-based nanocomposites containing 3 wt% of inorganics are accordingly prepared. The direct blend of SAN/organomodified clay is also prepared for sake of comparison. The clay dispersion is characterized by wide-angle X-ray diffraction (WAXD), atomic force microscopy (AFM), and solid state NMR spectroscopy measurements. The thermal properties are studied by thermogravimetric analysis. The flame retardancy and gas barrier resistance properties of nanocomposites are discussed both as a function of the clay dispersion and of the matrix/clay interaction.

“…b. In-situ intercalative polymerization method ( Fig. 6) [Biswas & Sinha-Ray, 2001;Kojima et al, 1993;Usuki et al, 1993;Okamoto et al, 2000Okamoto et al, , 2001Leu et al, 2002;Kim et al, 2003 ]: In this method, the layered silicate is swollen within the liquid monomer or a monomer solution so that polymer formation can occur between the intercalated sheets. Polymerization can be initiated either by heat or by radiation, by the diffusion of a suitable initiator, or by an organic initiator or catalyst fixed through cation exchange inside the interlayer before the swelling step.…”

“…Generally, nanocomposite is a multiphase dense material in which at least one of its phase has either one, two or three measurements lower than 100 nm [46]. The nanocomposites exhibit unique characteristics and comparably better properties than conventional or traditional composites such as glass fiber reinforced composites [47]. Nowadays, a great deal of research and study are in progress towards various fillers to form a huge variety of nanocomposites.…”

Abstract:The increasing demand for greener and biodegradable materials leading to the satisfaction of society requires a compelling towards the advancement of nano-materials science. The polymeric matrix materials with suitable and proper filler, better filler/matrix interaction together with advanced and new methods or approaches are able to develop polymeric composites which shows great prospective applications in constructions and buildings, automotive, aerospace and packaging industries. The biodegradability of the natural fibers is considered as the most important and interesting aspects of their utilization in polymeric materials. Nanocomposite shows considerable applications in different fields because of larger surface area, and greater aspect ratio, with fascinating properties. Being environmentally friendly, applications of nanocomposites offer new technology and business opportunities for several sectors, such as aerospace, automotive, electronics, and biotechnology industries. Hybrid bio-based composites that exploit the synergy between natural fibers in a nano-reinforced bio-based polymer can lead to improved properties along with maintaining environmental appeal. This review article intended to present information about diverse classes of natural fibers, nanofiller, cellulosic fiber based composite, nanocomposite, and natural fiber/nanofiller-based hybrid composite with specific concern to their applications. It will also provide summary of the emerging new OPEN ACCESSPolymers 2014, 6 2248 aspects of nanotechnology for development of hybrid composites for the sustainable and greener environment.
