Melt processing is challenging for recycling of mineral-filled polypropylene (PP) composites because the melt flow system, the viscoelasticity and the appearance of the extrudate profile change due to a combination of extensive shear forces and thermal-oxidative degradation. The flow pattern and the swelling behaviour of polypropylene-co-ethylene-kaolin (PP-co-E-kaolin) composite with 20% (by wt) kaolin and 5% (by wt) maleic anhydride-graft-polypropylene (PP-g-Ma) were distinguished using a sing...

Poly(eugenol-co-methylmethacrylate)/polypropylene blends were successfully prepared using methyl methacrylate (MMA), eugenol (Eg) and polypropylene (PP). First, poly(eugenol-co-methylmethacrylate) (poly(Eg-co-MMA)) was synthesized by photopolymerizaiton in one step at ambient temperature and without solvent. Benzophenone and triethylamine were used as photoinitiator and hydrogen donor, respectively. The second stage is the blending approach between polypropylene and poly(Eg-co-MMA) copolymer. Th...

Bioactive polymeric nanocomposites are indispensable materials and have received great attention owing to their diverse applications in human body. In this study, a poly(hydroxyethyl methacrylate) (pHEMA) complex was prepared using hydroxyethyl methacrylate (HEMA) as a base material and trimethylolpropane trimethacrylate (TMPTA) and benzoyl peroxide (BPO) as cross-linking agents. The pHEMA nanocomposites were prepared by melt processing technique. In this process, a twin screw extruder machine w...

Flexible membranes of poly(oxyphenylene benzimidazole) (PBIO) polymer with oxygen in the main chain were prepared. Proton conductivity was improved by sulfonation and adding magnetite to the PBIO membrane. A hydrophilic PBIO polymer/polyvinylidene difluoride (PVDF) mixture was used to prepare the membrane. DMF/acetone solvent pair was used to obtain homogeneous solutions of these two polymers. By modifying the PBIO with sulfuric acid, the PBIO membrane and PBIOsm composite membrane were obtained...

The impact of styrene–butadiene–styrene (SBS) and maleated styrene–ethylene–butylene–styrene (SEBS-g-MA) weight ratios was studied on the microstructure and ultimate performance of PP/PBT/(SBS + SEBS-g-MA) (70/15/15) blends. Morphological observations revealed a gradual change in the dispersions state of modifier domains from isolated phases to stack formation and then to encapsulation morphology as the SEBS-g-MA proportion was steadily increased. This was accompanied by improved blend homogenei...

Tensile strength and impact toughness of inter-layer hybrid composites, made of twill woven E-glass fabric and unidirectional carbon fiber in epoxy resin matrix with/without surface crack, were experimentally investigated. Hybrid laminates with eight, ten and twelve layers were prepared by employing the vacuum-assisted resin transfer molding method, while carbon and E-glass layers were stacked in an alternating sequence. Specimens were cut for uniaxial tensile loading, low-velocity Charpy impact...

Graphene decorated with cooper nanostructures were prepared with and without ionic liquid (IL) using different milling times. The obtained samples were characterized by Raman, X-ray diffraction (XRD) and transmission electron microscopy (TEM), to analyze the effect of the grinding time on the copper particles adhesion to the graphene sheets. Composites of silicon with two contents of G/Cu, at two weight ratios, nanostructures were prepared and the crosslinking characteristics were analyzed by a ...

Poorly soluble drugs are often a challenging problem in drug formulation. Midazolam is considered one of the best first-line drugs in managing status epilepticus in children who require emergency drug treatment. Owing to poor water solubility, however, oral bioavailability of midazolam is relatively low and insufficient. To improve its dissolution and absorption, nanosuspensions of midazolam hydrochloride were formulated with different stabilizers, such as Tween 80, Poloxamer 188, sodium carboxy...
