This paper presents an overview on recent developments of imogolite reinforced nanocomposites, including fundamental structure, synthesis/purification of imogolite, physicochemical properties of nanocomposites and potential applications in industry. The naturally derived nanotubular material of imogolite represents a distinctive class of nanofiller for industrially significant polymer. The inco...

Ionic liquids can typically be synthesized via protonation, alkylation, metathesis, or neutralization reactions. The many types of ionic have increased their attractiveness to researchers for employment in various areas, including polymer composites. Recently, been employed modify nanofillers the fabrication nanocomposites with improved physicochemical properties. In this succinct review, four ...

Abstract Nanofiller reinforcing agents can significantly improve the strength and modulus of polymer foams. But these improvements are often accompanied by changes in foam density (or equivalently the expansion ratio or void volume). The efficacy of nanofillers as reinforcing agents can only be judged once the density differences are accounted for. We review the literature and show that represe...

It is challenging to reinforce and toughen thermoset epoxy resins. We describe a slurry-compounding technique to transfer a uniform dispersion of chitin nanowhiskers (CW) in ethanol into an epoxy matrix. The incorporation of the hydrophilic CW reinforces the oil-soluble diglycidyl ether of bisphenol A (DGEBA). The resultant CW/epoxy bionanocomposites were transparent and showed considerably enh...

Vermiculite (Ver) enriched with silver and copper was used as nanofiller to the polyethylene (PE) matrix. Specifically, the low density polyethylene (LDPE) was chosen as a matrix. The samples Ver-Ag,Cu were prepared by shaking of Ver with the aqueous solutions of silver and copper nitrate. The mixtures of the Ver nanofillers and PE were homogenized by melt compounding technique and further thin...

INTRODUCTION Combining polymers with an organic or inorganic filler to produce a polymer composite is common in the production and processing of modern plastics. Recently, filler sizes have been reduced to nanometer dimensions resulting in a new class of materials termed polymer nanocomposites (PNC). PNCs are commonly defined as the combination of a polymer matrix resin with inclusions that hav...

objective: the purpose of the study was to evaluate the influence of adding nanofiller particles to a dentin bonding agent on resin-dentin bond strength. materials and methods: fifty-four human intact premolar teeth were divided in to 6 groups of nine. the teeth were ground on occlusal surfaces and polished with 320 and then 600 grit silicon carbide papers. an experimental bonding system based ...

molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...
