“…Simillar results have been reported by Khanjanzadeh et al (2013) and Zahedi et al (2015). As mentioned by others, NC most likely acted as barrier, providing prolonged pathways for the water molecules and reducing the hydrophilicity (Alexandre et al 2006). Alternatively, nanoparticles could obstruct the capillaries in WSF so that water cannot flow (Shi et al 2007).…”

The goal of this work was to evaluate the technical feasibility of walnut shell flour (WSF) as substitute for wood in walnut shell flour/thermoplastic starch (WSF/TPS) composites. The effects of walnut shell flour (WSF), thermoplastic starch (TPS), and nanoclay on the physical and mechanical properties of WSF/TPS composites were investigated. The composite samples were formed in a Colin extruder with four-chamber heat with temperatures. Then, test samples were made using injection molding. The addition of up to 40% WSF greatly improved the tensile strength, flexural strength, and elasticity modulus of the composite. Also, the composites made with higher WSF contents had increased thickness swelling and water absorption. The incorporation of nanoclay (0% to 5%), greatly improved the tensile properties. Soil burial degradation experiments showed that biodegradation was accelerated by the increase of starch in the composite mixtures. The study showed that WSF can be successfully utilized for the manufacture of composites with useful physical and mechanical properties.

“…First, the hydrophilic surface of clay platelets acted as an immobilizer of the moisture [86] . The second mechanism is the formation of a tortuous path by the clay platelets [87,88] . As a result, the barrier properties of nanocomposites will be enhanced and the water molecules will be hindered [80] .…”

The water absorption behavior, mechanical and thermal properties of vinyl ester matrix nanocomposites based on layered silicate were investigated. To characterize interlaminar structure of the nanocomposites, XRD, SEM, EDS, and TEM were performed. The mechanical and thermal properties of neat sample were improved by the incorporation of layered silicate. The improvement of the water repellence behavior was observed for the nanocomposites. The hardness and elastic moduli after water absorption was reduced due to the effect of water molecules entering into the polymer chains. However, the higher amount of clay reinforcement led to less reduction in hardness since the barrier properties.

Templated formation of silver nanoparticles using amphiphilic poly(epichlorohydrine-g-styrene) film

et al. 2009

This work has demonstrated that a novel amphiphilic poly(epichlorohydrine)-graft-polystyrene (PECHg-PS) copolymer at 34:66 wt% was synthesized via atom transfer radical polymerization (ATRP) of styrene using PECH as a macroinitiator. The structure of the graft copolymer was characterized by nuclear magnetic resonance ( 1 H NMR) and FTIR spectroscopy, demonstrating that the "grafting from" method using ATRP was successful. The self-assembled graft copolymer was used as a template film for the in-situ growth of silver nanoparticles from AgCF 3 SO 3 precursor under UV irradiation. The in situ formation of silver nanoparticles with 6-8 nm in average size in the solid state template film was confirmed by transmission electron microscopy (TEM), UV-visible spectroscopy and wide angle X-ray scattering (WAXS). Differential scanning calorimetry (DSC) also displayed the selective incorporation and the in situ formation of silver nanoparticles within the hydrophilic PECH domains, probably due to stronger interaction of the silvers with the ether oxygens of PECH backbone than that with hydrophobic PS side chains.
