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...
The purpose of this contribution is to investigate different mechanical properties various types rubber composite materials that were filled with carbon black nanofiller. composites produced from three basic rubbers. Moreover, the volume concentrations rubbers including their ratios. Mechanical tested investigated by means tensile testing, Shore hardness, rebound resilience, friction, abrasion,...
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...
The continuity and thickness of the coating layer, are the most important factors in wetting properties and strength of carbon fibers. These factors are crucial in the quality of metal matrix composites made with carbon fibers. In this research the Polyacrylonitrail base carbon fibers have been nickel coated with 0.2, 0.5, 0.8 and 11 ,u in thickness, by the electroless method. The effect of the...
We study the aggregation of carbon allotrope nanofillers in matrix isotactic polypropylene with direct small-angle neutron scattering measurements. With ATSAS software, we analyzed data and determined fractal shape, dimension, sizes nanofiller bulk over range angles. estimated volume distributions different types at concentrations: nanographite, graphene nanoplatelets (GNP), fullerenes, single-...
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 ...
The design and necessity of corrosion-resisting nanocarbon nanocomposites have been investigated for cutting-edge aerospace applications. In this regard, nanofillers, especially carbon nanotubes, graphene, nanodiamond, etc. used to fill in various polymeric matrices (thermosets, thermoplastics, conducting polymers) develop anti-rusting space-related nanocomposites. This review fundamentally emp...
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 ...
