Composites based on PLA with the addition of 3, 6 and 10 wt% silica, hydroxyapatite bentonite were obtained by twin-screw extrusion. Maleic anhydride grafted polyethylene was used to enhance interface interactions. The influence fillers Charpy impact strength, Rockwell hardness, tensile properties processing shrinkage investigated. Test samples 3D printing. highest strength hardness for composi...

The filamentous fungus Byssochlamys fulva strain IMI 40021 produces (+)-byssochlamic acid 1, its novel dihydroanalogue 2 and four related secondary metabolites. Agnestadrides A, 17 and B, 18 constitute a novel class of seven-membered ring, maleic anhydride-containing (hence termed heptadride) natural products. The putative maleic anhydride precursor 5 for both nonadride and heptadride biosynthe...

Nanocomposites of isotactic polypropylene (iPP) and date wood fiber were prepared after modification of the host matrix by reactive extrusion grafting of maleic anhydride. Chemical and mechanical treatment of date wood flour (WF) was conducted to obtain nanocrystalline cellulose. Layered silicates (clay) were partially intercalated with date wood fiber, and the modified layered silicate was use...

Durian skin is a newly explores natural fibre potentially reinforced polyolefin for diverse applications. In this work, investigation on the effect of coupling agent, maleic anhydride polypropylene (MAPP) on the mechanical, morphological, and thermal properties of polypropylene (PP) reinforced with durian skin fibre (DSF) was conducted. The presence of 30 wt% DSF significantly reduced the tensi...

Dynamic dielectric properties of an isotactic polypropylene matrix grafted with maleic anhydride (CA 100) and then crosslinked by polyether amine molecules reinforced different weight percentages graphite nanoplatelets (GNPs), KNG180, were studied for the first time compared to those obtained DMA (Dynamic Mechanical Analysis). The main objective this work was investigate reinforcement effect GN...

Abstract Cysteamine functionalised reduced graphene oxide (rGO) was grafted to polypropylene-graft-maleic anhydride (PP-g-MA) and subsequently melt blended with PP. The covalent bridging of rGO PP-g-MA via the cysteamine molecule co-crystallization are routes promoting interfacial interactions between PP matrix. A rheological percolation threshold achieved for a nanofiller loading 3 wt% 5 wt%, ...
