phenolic resins have been widely used for selective high technology applications due to their excellent ablative properties, structural integrity and thermal stability that make them appropriate for thermal insulation materials, wood products industry, coatings, moulding compounds and composite materials. polymer layered silicate nanocomposites based on montmorillonite (mmt) have attracted a gr...

A silicotungstic acid (STA) was successfully impregnated onto K10 montmorillonite (MMT) in an effort to improve the properties of SPEEK membrane. Several characterizations such as Fourier transform infrared (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were carried out in order to confirm the entrapment of STA molecule onto MMT. It was found that the ST...

Composite membranes have been synthesized from biopolymer chitosan (CS) and nanosized montmorillonite (MMT) filler crosslinked with sulfosuccinic acid (SSA) as an alternative membrane electrolyte for direct methanol fuel cell (DMFC) application. All prepared were obtained by solution casting technique. Prepared systematically characterized in terms of water uptake, permeability performance para...

In this work, a magnetically separable montmorillonite/Fe3O4 sphere composite (MMT/Fe) was synthesized by simple polyol thermal method. The characteristics of the as-preparation composites were checked XRD, SEM, PL technologies. addition, photocatalytic activities products degradation Rhodamin B (RhB) under visible light. results showed that MMT/Fe exhibited high activity for RhB removal light ...

The core-shell structure in oriented cylindrical rods of polypropylene (PP) and nanoclay composites (NCs) from PP and montmorillonite (MMT) is studied by microbeam small-angle x-ray scattering (SAXS). The structure of neat PP is almost homogeneous across the rod showing regular semicrystalline stacks. In the NCs the discrete SAXS of arranged crystalline PP domains is limited to a skin zone of 3...

Prior studies of clay-virus interactions have focused on the stability and infectivity of nonenveloped viruses, yielding contradictory results. We hypothesize that the surface charge distribution of the clay and virus envelope dictates how the components react and affect aggregation, viral stability, and infectivity. The bacteriophage Cystoviridae species φ6 used in this study is a good model f...

Monoclonal antibodies as polymeric nanoparticles are quite interesting and endow this new drug category with many advantages, especially by reducing the number of adverse reactions and, in the case of radiopharmaceuticals, also reducing the amount of radiation (dose) administered to the patient. In this study, a nanoradiopharmaceutical was developed using polylactic acid (PLA)/polyvinyl alcohol...

Pyrene removal by polycation-montmorillonite (MMT) composites and granulated activated carbon (GAC) in the presence of humic acid (HA) was examined. Pyrene, HA, and sorbent interactions were characterized by FTIR, fluorescence and zeta measurements, adsorption, and column filtration experiments. Pyrene binding coefficients to the macromolecules were in the order of PVPcoS (poly-4-vinylpiridine-...

In the recent past, significant research effort has been dedicated to examining usage of nanomaterials hybridized with lignocellulosic fibers as reinforcement in fabrication polymer nanocomposites. The introduction nanoparticles like montmorillonite (MMT) nanoclay was found increase strength, modulus elasticity and stiffness composites provide thermal stability. resulting composite materials fi...

Low-density polyethylene (LDPE) is an important thermoplastic material which can be made into films, containers, wires, cables, etc. It highly valued in the fields of packaging, medicine, and health, as well cables. The method improving dielectric property materials by blending LDPE with inorganic particles filler has been paid much attention researchers. In this paper, low-density used matrix,...
