The mechanical properties of nanocomposites are significantly affected by the dispersion nanofillers. In this study, synergetic effect hybrid fillers, including surfacemodified montmorillonite (MMT) nanoclay and graphene nanoplatelets (GNPs) on quality characteristics epoxy-based was investigated. It manifested that incorporation GNPs-MMT into pure epoxy improves consequently, tensile flexural ...

Materials methods: AgNPs were synthesized by the chemical reducing method. Characterization done using Field emission scanning electron microscope (FE-SEM), X-ray diffraction analysis (XRD) Thermogravimetric (...

In the present work, Na+-montmorillonite nanoclay (Na-MMT) was functionalized using 3-aminopropyltrimethoxysilane (3-APTMS) as a coupling agent. The covalent functionalization of MMT was confirmed by Fourier-transform infrared spectroscopy (FT-IR). In the specimen fabrication stage, 5 wt% of pristine MMT or silane-functionalized MMT (f-MMT) were incorporated into an epoxy system and the resulta...

Back Cover: In article number 2100233 by Chungyeon Cho and co-workers, in an effort to develop highly functionalized flame retardant materials, polymer nanocomposites are assembled alternately depositing polyaniline (PANi) carbon nanotubes (CNTs), stabilized montmorillonite (MMT) aqueous solution, via the layer-by-layer assembly technique. Incorporation of CNTs into a polymeric multilayer nanoc...

Polyvinyl chloride (PVC) is one of the world’s most widely produced polymers and it is used in a wide range of areas such as building, transport, packaging, electrical/electronic and healthcare. Manufacturing of PVC products is dependent on several additives, e.g. plasticizers, heat stabilizers and flame retardants. To reduce the migration of additives in PVC products the incorporation of a nan...

This work evaluated the synergistic effect of citronella essential oil (Ct) and montmorillonite (MMT) (called hybrid compound) incorporated in Poly(lactic acid) (PLA) films at different concentrations (3, 10, 15, 20 wt%). PLA were characterized using X-ray diffraction, SEM, TGA, DSC considering their mechanical properties migration. XRD analysis showed effective interaction between MMT oil. The...

The effect of varying amounts of montmorillonite (MMT) filler (in weight ratios of 100/0, 100/5, and 100/10) on the molecular dynamics and polarization of atactic poly(methyl methacrylate) (PMMA) is investigated using broad-band dielectric spectroscopy from 10 −2 to 10 6 Hz and at temperatures from 30 to 140 °C. The experimental data were analyzed with the sum of Havriliak–Negami (HN) functions...

A novel fabrication of polymer composite fibers using polycaprolactone (PCL), montmorillonite nanoclay (MMT-Clay), and nano-hydroxyapatite-clay (HAP MMT-Clay) is reported for bone tissue engineering applications. Using a pressurized gyration (PG) setup, (PCL) incorporated with in situ mineralized HAP MMT-Clay were investigated. the method, we able to successfully manufacture HAP-nanoclay-PCL fi...

A nanohybrid was prepared with an inorganic clay material, montmorillonite (MMT), for taste masking of sildenafil (SDN). To further improve the taste-masking efficiency and enhance the drug-release rate, we coated the nanohybrid of SDN-MMT with a basic polymer, polyvinylacetal diethylaminoacetate (AEA). Powder X-ray diffraction and Fourier transform infrared experiments showed that SDN was succ...

A facile and environmentally friendly method was introduced to incorporate montmorillonite (MMT) as an inorganic phase into quaternized hemicelluloses (QH) for forming hemicellulose-based films. Two fillers, polyvinyl alcohol (PVA) and chitin nanowhiskers (NCH), were added into the hemicelluloses/MMT hybrid matrices to prepare hybrid films, respectively. The hybrid films were nanocomposites wit...
