This work presents the preparation and characterization of compression-moulded montmorillonite and carbon nanofibrepolypropylene foams. The influence of these nanofillers on the foaming behaviour was analyzed in terms of the foaming parameters and final cellular structure and morphology of the foams. Both nanofillers induced the formation of a more isometric-like cellular structure in the foams...

A series of nanocomposites have been prepared from perfluorosulfonylfluoride copolymer resin (Nafion) and layered montmorillonite (MMT) modified with protonated dodecylamine by conventional sol-gel intercalation. The structure of these nanocomposite materials have been characterized using FT-IR, elemental analysis, XRD and solid state NMR techniques, including 19F magic-angle spinning (MAS) NMR...

introduction: biodegradable films for food packaging applications have attracted an increasing amount of consideration over the last two decades, predominantly due to environmental pollution and the realization that our petroleum resources are not infinite. starch, which is one of the natural biopolymers, has been considered as one of the best candidates primarily because of its processbility, ...

the aim of this study was to investigate the rate of water vapor permeability (wvp) and moisture sorption of starch-montmorillonite (mmt) nanocomposite films. the nanocomposite films were prepared using the casting method andglycerol was used as a plasticizer. the effect of glycerol concentration on wvp of the films was determined at 25°c with a relative humidity of 0-99% (inside and outside of...

Herein, flexible polyvinylidenefluoride (PVDF) nanocomposite films reinforced with different concentrations of graphene nanoplatelets (GNPs), montmorillonite (MMT) nanoclay and titanium dioxide (TiO2) nanoparticles (NPs) were prepared using a simple low-cost solution casting method. The surface morphology PVDF/GNPs/TiO2/MMT nanocomposites the interaction between PVDF, GNPs, TiO2 NPs MMT nanofil...

The novel nanocomposite membranes were successfully prepared by the incorporation of different concentrations (5, 10, and 15 wt%) of montmorillonite (MMT) as a nanoadditive into a blend of chitosan/polystyrene (CS/PS) at a ratio of 3:1 on the basis of solution-casting method and they were subsequently used for the separation of phenol, p-chlorophenol, and 2,4-dichlorophenol from water through p...

Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. Depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. The effects of montmorillonite (MMT), glycerol (GL), and thei...

The ability of commercial nanofillers Nanofil, Cloisite and by own way prepared MMT/ODA for PE and PP matrix was evaluated. Different types of mentioned type of nanofillers were added into polyethylene (PE) and polypropylene (PP) matrix in various concentrations. The amount of clays was calculated as 3 and 5 wt% to the weight of PE/PP. The PE/PP and nanofillers were mixed on a one screw KO Knea...
