Abstract Cellulose mixed esters (CMEs) substituted with two different types of acyl groups are promising polymeric materials various tunable properties but arduous to produce. This is because the insolubility cellulose in common solvents, and thus, industrial production CMEs desired degrees substitution (DSs) requires a costly multistep process. To accomplish their facile production, homogeneou...

The use of date palm fibres, which are an abundant by-product agriculture, as natural reinforcement in polypropylene (PP) was studied. Because odour emissions one the major challenges for fibre-based composites, emission Volatile Organic Compounds (VOC) generated at different processing steps analysed online. severest degradation on fibre morphology observed injection moulding step, but even wh...

Abstract The environmental impact of rubber waste can be reduced by extending the lifetime products. It achieved developing graphene/rubber nanocomposites with good abrasion resistance. In this paper, we investigated how mixing technologies influence mechanical properties rubber. We added various amounts (0, 1, 5 and 10 phr) graphite graphene to mixtures using a two-roll mill, an internal mixer...

The effect of gamma irradiation on neat Polyamide-11 (PA11) and PA11 filled with 3 wt% halloysite nanotubes (HNTs) was investigated at various doses up to 100 kGy in air room temperature. test conducted sample films prepared by a twin-screw extruder the first step then cast extrusion. study showed formation maximum gel fraction 10 20 for PA11/HNTs, respectively. Furthermore, results indicated o...

Abstract. In this research, four novel types of hyperbranched polyester polymers (HBPs) were used and blended with polypropylene polymer PP, virgin VPP recycled rPP, using a twin-screw extrusion machine. Hyperbranched was added in different weight ratios (5%, 10%, 20%). The Fourier transform spectroscopy FTIR, the water contact angle CA, biodegradation soil, rheological properties (melt flow ra...
