This article aims to study recycled biochar (R-BCH) improvements on the high-density polyethylene (HDPE) matrix properties. A series of composites was developed with a different loading varying from 0 10 wt.% R-BCH, using twin-screw extruder followed by compression molding. The results were showed that addition 3-10% R-BCH in pure HDPE led an increase tensile strength, modulus elasticity, and d...

Immiscible blends of ethylene?propylene?diene?monomer (EPDM) and polyoxymethylene (POM), when EPDM is the major phase were compatibilized on addition an ionomer, poly(ethylene?co?methacrylic acid). The inclusion ionomer reduced interfacial tension between two phases, such that diameter POM domains significantly to 0.5 2 ?m, typical required toughen ductile polymers. mechanical properties result...

Development of nanofilters with the ability to remove toxic metal ions from effluent wastewater will be immense help leather industry. In this study, fibrous nanofilter (FNF) was prepared using microfibrillated cellulose and tea leaf microparticles blended in poly (vinyl) alcohol. FNF analysed for its efficacy hazardous metals tannery wastewater. The had promising traits tensile strength (19.24...

• Nanoarchitectonics approach to synthesize functionalized CNTs was proposed. were using new multifunctional initiators. Nanocomposites with MPIs fabricated. New nanocomposites possessed improved physic-mechanical properties. In this work, the nanoarchitectonics a functional material certain configurations and hierarchical motifs of initiators surface-initiated radical polymerization (MPIs) on ...

Abstract In this work, chitosan (CT) with different ratios (0–5 wt.%) was utilized as a bio filler in polyurethane flexible (PUF) foam to increase mechanical performance and bacterial inhibition characteristics. The chemical structure of CT foam/ (PUF/CT) composites examined using FTIR spectroscopy. Furthermore, the cross-link density PUF/CT Flory Rhener equation. Moreover, composites’ thermal ...

Polylactic acid (PLA) was melt-blended with epoxy resin to study the effects of reaction on mechanical and thermal properties PLA. The addition 0.5% (wt/wt) PLA increased maximum tensile strength (57.5 MPa) 67 MPa, whereas 20% improved elongation at break 12%, due crosslinking caused by reaction. morphology PLA/epoxy blends showed nanoparticle dispersion in matrix that presented a smooth fractu...

Poly (lactic-co-glycolic acid) (PLGA) is a kind of medical polymer material with good biodegradability and histocompatibility, which widely used in postoperative anti-adhesion materials. In this paper, PLGA microfiber membrane was successfully prepared poly(lactic-co-glycolic as the main by electrospinning technology. The surface morphology, wettability, dimensional stability mechanical propert...

Hydroxyapatite is a biocompatible ceramic and reinforcement for bone implantations. SEVA/HAP composite content HAP filler with difference particle sizes were designed. Mechanical tests like tensile modulus, UTS, strain at break and biodegradation were investigated. Results illustrated much increase tensile modulus of composites content HAP nano powders ratio to micro powders. Also UTS analysis ...
