Suspensions of nanoparticles (SiO2, SiC, TiO2, CNT, Nanoclay and Hydroxyapatite) were spray dried to produce dry granulated products. The nanoparticles were consolidated in granules making them more convenient and safer to use in further processing compared to handling of nanopowders.

The current study aims to investigate the effect of fillers with different geometries and sizes on the interfacial shear properties of PA6 composites with de-sized carbon fiber. The fillers which have been investigated are namely; nano-layer silicates (nanoclay), sub-micro aluminum titanium (ALTi) particles, and multiwall carbon nanotube (MWCNT). By means of X-ray photoelectron spectroscopy (XP...

introduction: nanocomposites are prepared by introduction of dispersed nanoscale particles into the polymer matrix based on four methods: template synthesis (sol-gel preparation); intercalation of polymer; and in situ intercalative polymerization and last one is melt blending, the most favorable and practical method due to its simplest, economical and environmentally friendly technic. this meth...

New polyurethane (PU) nanocomposites were prepared from a dispersion of 0 - 5% montmorillonite (MMT) clay with isocyanate and soya oil polyol that was synthesized via transesterification of triglycerides to reduce petroleum dependence. FT-IR spectra indicate the presence of hydrogen bonding between nanoclay and the polymer matrix, whereas the exfoliated structure of clay layers was confirmed by...

In this study, a comparison between neat poly(vinylidene fluoride) (PVDF) membrane and composite (PVDF-Nanoclay and PVDF-PVP-Nanoclay) membranes is presented. All membranes were synthesized by the phase inversion process, using 18% PVDF, n-methylpyrrolidone as solvent and water as the non-solvent. Demineralized water cross-flow permeation tests were conducted to evaluate the membranes performan...

In this paper, different types and particle sizes of nanoclay (nano-metakaolin—NMK—and nano-attapulgite—NMA—clay) were selected to study the effect on properties cement-based cementitious materials. The stability dispersions was analyzed. effects mechanical cracking behavior cement mortar discussed. crack propagation analyzed by flat knife-edge induced constraint ring experiments. research show...

the high hydrophilic property of biopolymer based plastics is one of the most important defects of them. blending biopolymers with compatible synthetic polymers and using nano particles such as nanoclay as nanofiller are improving methods that have been extensively considered in recent years. carboxymethyl cellulose (cmc) is one of the lowest cost biopolymers that have enormous applications in ...

Due to their biodegradability, affordability, low density, and numerous other benefits, natural fiber polymer composites are preferable conventional GFRP in maritime applications. However, when exposed moisture, mechanical qualities deteriorate. A significant agricultural waste called pineapple leaf (PALF) can be employed as reinforcement epoxy matrices. Improved interfacial bonding between pha...
