However, due to the high melting points of these polyesters (>300° C.) processing is rather difficult. The homopolyester of 4-hydroxyphenyl acetic acid and its polyester with 4-hydroxy benzoic acid are melt processable liquid crystalline polymers exhibiting clear nematic phase. The terpolyesters ...
Small-molecule OSCs have traditionally led the field in terms of high-performance devices, but high-mobility polymers are becoming increasingly competitive2,8. Both have exceeded the performance of amorphous silicon and can even possess charge carrier mobilities within the same order of magnitude as p...
emission and electrical conductivity, and provides an excellent platform for investigating structure–property relations. It is, however, challenging to efficiently tune the polymorphism of conjugated polymers in aggregated, semi-crystalline phases due to their conformational...
The growth of transcrystalline regions in the melt matrix at the interface plus an observed partial melting between fibre and matrix are indications of a strong and intimate interfacial bond with a gradient in morphologies for the system studied, high-density polyethylene. The pull-out test is a...
Measuring the peeling strength between polymers (low density polyethylene, ethylene propylene diene monomer (EPDM) rubber) and brass and evaluating the effect of thermal and chemical oxidation on the metal - ScienceDirectLow density polyethylene (LDPE)...
“I recognised that block copolymers with PE and iPP might have the capability of compatibilising these separate polymers, so we simply tried it. Our lab has quite a bit of expertise in making block copolymers,” Coates toldThe Chemical Engineer. ...
Cardboard Polyethylene (PE) 1. Introduction Pyrolysis offers higher flexibility than other processes in terms of waste valorization, as it converts waste into the three different products of oil, syngas, and char. In addition, these pyrolysis products could potentially be upgraded into products with...
of molecularweight.In this application note, the BeNano 90 Zeta (Bettersize Instruments Ltd.) was utilized to characterize the molecular weight ofa polyethylene oxide (PEO) standard dissolved in water using SLS method. The results will endorse the ability of BeNano 90Zeta for charactering molecular...
1a, b). Injection-molded samples and films were placed in custom-made sample holders and mesh bags, respectively, and were placed on the deep-sea floor in a condition that prevented physical deformation [samples were placed in polyethylene terephthalate (PET) containers with holes, protected by ...
Polyethylene (C2H4)n was compressed to pressures between 10 and 30 GPa in a diamond anvil cell (DAC) and laser heated above 2500 K for approximately one second. This resulted in the chemical decomposition of the polymer into carbon and hydrocar
