The conformation of polymer chains under confinement is investigated in intercalated polymer/layered silicate nanocomposites. Hydrophilic poly(ethylene oxide)/sodium montmorillonite, PEO/Na+-MMT, hybrids were prepared utilizing melt intercalation with compositions where the polymer chains are mostly within the ~1 nm galleries of the inorganic material. The polymer chains are completely amorphou...

Abstract Supercritical CO 2 -assisted extrusion technique was used to produce flame retarded foams from recycled poly(ethylene terephthalate) (rPET). Synergistic combination of aluminium-alkylphosphinate retardant (FR) and natural montmorillonite (MMT) utilised provide adequate retardancy at moderate loadings, i.e. with less than 9% additives. Addition FR found increase the rate degradation dur...

Abstract The electrochemical behavior of Vildagliptin (VILD) was studied using the cyclic voltammetric technique in an aqueous Britton–Robinson (BR) universal buffer solution various pH levels between 4.0 and 10 at a 5% calcium-montmorillonite clay modified with carbon paste electrode surface (5% Ca-MMT/CPE). results exhibited irreversible anodic peak about 1.238 V versus Ag/AgCl, KCl (3 mol L ...

Objective: The aim of the present study is to develop pH-responsive polymeric microbeads for controlled release doxorubicin. Methods: Doxorubicin-encapsulated were developed by a simple ionotropic gelation method using sodium alginate, gum ghatti, and montmorillonite (MMT). In this work, we investigate positive benefits MMT mineral as drug carrier DOX. X-ray diffraction (XRD), Fourier transform...

The application of nanomaterials as a strengthening agent in the fabrication polymer nanocomposites has gained significant attention due to distinctive properties which can be utilised structural applications. In this study, reduced graphene oxide (r-GO) and montmorillonite (MMT) nanoclay were used filler materials fabricate hybrid epoxy-based nanocomposites. synergistic effect on flammability ...

Nanocomposites of PMMA+MMT Brazilian clays were developed by mechanical mixing in co-rotational twinscrew extrusion and injection molding with varying weight fraction of MMT Brazilian clays. The clays were purchased in crude form and then washed and purified to extract the organic materials and contaminants. Dynamic friction and wear rate of these composites were studied as a function of concen...
