The effect of the branch content (BC) and composition distribution (CD) of linear low-density polyethylene (LLDPE) on the thermal and mechanical properties of its blends with LDPE were studied. All blends and pure resins were conditioned in a Haake PolyDrive blender at 190°C and in the presence of adequate amounts of antioxidant. Two metallocene LLDPEs (m-LLDPE) and one Ziegler–Natta (ZN) hexen...

The waste created by single-use plastics is an important global issue, especially in marine environments, because they do not degrade nature. This work aimed to study the biodegradability of bioplastic blown film, which may pose a solution this problem. Polybutylene succinate (PBS) and polylactic acid (PLA) films were chosen for examination their when submerged sand under seawater floated on su...

The conductivity of high-resistivity polymer films is dependent on the magnitude of applied electric field, repeated electric field exposure, and sample temperature. A traditional constant voltage method was used, maintained under vacuum to more closely resemble the space environment. Both the strength of the applied voltage and the thickness of low-density polyethylene (LDPE) samples were vari...

We estimate the energy content, the operational energy inputs, and the net energy ratio (NER) of an industrial tubular photobioreactor used for the photosynthetic production of H2 by microalgae. The calculated H2 output of the photobioreactor is based on a range of algal photosynthetic H2 generation efficiencies, and on the application of standard theory for tubular solar collectors. Small diam...

Briquettes are solids that generally made from agricultural waste materials. Char briquettes one of the alternative energies for daily needs. This study used char palm shell and LDPE microwave-assisted co-pyrolysis at 450 Watts. The were product Low-Density Polyethylene (LDPE) with variations in composition 0:100, 50:50, 100:0 pressure 50 kg/cm2, 100 150 200 kg/cm2. In this research, thermograv...

PAL measurements were used to study the process of graft polymerization of methyl methacrylate (MMA) to low density polyethylene (LDPE). When the monomer was just sorbed to LDPE, both I, and z, were increased. When MMA was grafted to LDPE, on the other hand, they were decreased. These contrasting results suggests usefulness of the PAL method to study the micro-structures of polymers. Introducti...

Fullerene-60 nanoparticles were used for studying their influence upon the LDPE biodegradation efficiency of two potential polymer-degrading consortia comprising of three bacterial strains each. At a concentration of 0.01% (w/v) in minimal broth lacking dextrose, fullerene did not have any negative influence upon the consortial growth. However, fullerene was found to be detrimental for bacteria...

Plastic waste found in oceans has become a major concern because of its impact on marine organisms and human health. There is significant global interest recycling these materials, but their reclamation, sorting, cleaning, reprocessing, along with the degradation that occurs natural environment, all make it difficult to achieve high quality recycled resins from ocean plastic waste. To mitigate ...

The by-products of dicumyl peroxide (DCP) from the crosslinking process such as acetophenone, cumyl alcohol and α-methylstyrene are said to be the sources of space charge formation in XLPE cable due to deep traps in the chemicals. However, by using space-chargeexperimental approach, it appeared that these chemicals show a different trapping nature. This paper is intended to present this approac...
