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.

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...

Polyamide 6 (PA6) was melt-blended with an intumescent flame retardant (FR), multi-wall carbon nanotubes (MWNTs), and nanoclay particles to produce multi-component FR-PA6 nanocomposites. FR-PA6 nanofibers were processed from varied nanocomposite formulations via electrospinning. Electrospinnability, morphology, along with combustion and thermal properties of the nanofibers were investigated. Bo...

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...

background: flexural strength of prosthesis made with dental composite resin materials plays an important role in their survival. the aim of this study was investigating the effect of nanoclay fillers and poly (methyl methacrylate)-grafted (pmma-grafted) nanoclay fillers loading on the flexural strength of fiber-reinforced composites (frcs). materials and methods: standard frc bars (2 × 2 × 25 ...

We used an effective electrochemical sensor for the determination of imipramine at pH 7.2 using a carbon nanocomposite electrode. The electrode has been designed by incorporation of montmorillonite nanoclay into the carbon ionic liquid electrode. The high sensitivity of 1.714 μA (μM)-1, two linear calibration ranges of 0.1–2 μM and 2-40 μM, and detection limit of 19 nM were achieved. The relati...

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...

The current study’s objective is to investigate the impact of nanoclay on tensile and wear properties glass fiber-epoxy-nanoclay ternary nanocomposite. Three types composites are produced by hand lay-up process compression molding. Tensile tests executed according ASTM standards. findings disclosed that enhanced causes for failure under load revealed SEM micrographs. Response surface methodolog...
