In this study, the mechanical and thermal behavior of the nano-reinforced polymer composite reinforced by Montmorillonite (MMT) nanoparticles is investigated. Due to low cost of computations, the 3D representative volume elements (RVE) method is utilized using ABAQUS finite element commercial software. Low density poly ethylene (LDPE) and MMT are used as matrix and nanoparticle material, respec...

Square-planar polypyridine platinum(II) complexes have been introduced into a silica/polymer matrix by covalent ligand modification. The photophysical properties of the supported matrices are well retained as their model complexes, and the quantum yields for singlet oxygen ((1)O(2)) generation are comparable with that of TPP (tetraphenylporphyrin) under similar conditions. A preliminary applica...

the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

in this study, the effect of nanoclay particles content on the physical properties and flammability of composite made of high density polyethylene and wood flour was investigated. for this aim, wood flour was combined with hdpe at 50% by weight, and nanoclay was used in 0, 2, 4 and 6%, also 2% of mape as the coupling agent was used in all formulations. the samples were made in injection molding...

The aggregation and dispersion of two anisotropic nanoparticles (NPs), cubes and tetrahedrons, in a polymer matrix are studied in this work using coarse-grained molecular dynamics simulations. We present the phase diagrams of NP-polymer composites, depicting microscopically phase-separated, dispersed, and bridged cubes and tetrahedrons in a polymer matrix, which depend on the interaction betwee...

For the first time, we report the C4s’ transport properties: solubility, diffusivity, permeability in 6FDA–DAM polymer, one of most permeable glassy polymers with significant nC4 vs. iC4 selectivity. An nC4 permeability of 3.7 Barrer, and nC4/iC4 ideal selectivity of 21 was found in pure 6FDA–DAM polymer membrane. Mixed matrix films were successfully fabricated using a 6FDA–DAM as the matrix, w...

The objective of this study was to develop a sustained release matrix tablet Metoprolol Succinate by cost saving and production efficient process. Among various tablet manufacturing process, direct compression is the simplest and cost saving process. Different trials were formulated and evaluated using different concentrations of directly compressible grade Kollidon SR as release retardant. The...

The present study reports the preparation and evaluation of polymer composites of chitosan and montmorillonite. The prepared polymer composites were evaluated for various powder properties and characterized by FTIR-ATR (Fourier Transform Infrared Spectroscopy- Attenuated Total Reflectance), XRD (X Ray Diffraction), and SEM (Scaning Electron Microscopy) techniques. Heckel and Kawakita equations i...

Polymer nanocomposites are known to exhibit enhanced mechanical properties compared to neat polymeric system [1]. Fillers can be used as reinforcement in polymer composites for the enhancement of mechanical properties [2]. Reinforced” polymers consist of a polymeric matrix and relatively stiff filler that exhibit a drastic change in modulus or stress at given strain in compare with the pure pol...
