interaction of menthol with polyethylene terephthalate bottles during storage time was tested at three different temperatures. menthol is a mint flavor agent added to yogurt drinks in iran and is considered as a factor affecting consumer acceptance. absorption of menthol to packaging material could cause a loss of quality in the final product due to diminished flavor intensity. tests were done ...

Abstract Background The world today is faced with the humongous challenge of removing numerous plastic wastes in our environment. Efforts removal or remediation these materials from ecosystem are presently at budding stage. Some researchers have shown that certain bacterial enzymes ability to hydrolyze and further degrade compounds. In this study, PET hydrolase enzyme polyvinylchloride, polyure...

The effect of high shear rate on the mechanical properties polyethylene (PE), poly(ethylene terephthalate) (PET), polystyrene (PS) and polypropylene (PP) waste blend was investigated. process carried out at a temperature 120°C using counter-rotating twin-screw extruder. A constant screw speed 250 rpm weight ratio PE/ PET/PS/PP components 1:1:1:1 were used. preliminary research showed that had n...

nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. in this study pet nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. the morphology of pet/mica nanocomposites was characterized by x-ray diffraction and transmission electron mi...

Nanofiber membranes are widely employed to prepare composite filter media. The traditional method of hot pressing may damage the structure nanofiber membrane, and thus increase pressure drop through filter. In this study, three-dimensional PET/TPU (polyethylene terephthalate/thermoplastic polyurethane) filters (PET/TPU-CNF) with beads-on-string were fabricated by one-step co-electrospinning. Be...

The enzymatic depolymerization of synthetic polyesters has become great interest in recycling plastics. Most the research this area focuses on polyethylene terephthalate (PET) due to its widespread use various applications. However, activity other commercial is less frequently investigated. Therefore, Akestra TM attracted our attention, which a copolymer derived from PET with partially biobased...

Abstract Ideonella sakaiensis ( I. ) can grow on polyethylene terephthalate (PET) as the major carbon and energy source. Previous work has shown that PET conversion in presence of oxygen released dioxide water while yielding adenosine triphosphate (ATP) through oxidative phosphorylation. This study demonstrates is a facultative anaerobe ferments to feedstock chemicals acetate ethanol absence ox...

in this work, ito/pet (indium tin oxide / polyethylene terephthalate) electrode structure which provides biocompatibility, mechanical stability and flexibility is fabricated. flexible ito/pet implantable electrode array for a retina has been developed. the electrode array is fabricated on a thin pet/ito substrate and is encapsulated using, su-8, an insulating material. pet substrate and su-8 po...

The indiscriminate utilization of nondegradable polyethylene terephthalate (PET)-based products has triggered serious environmental pollution that to be resolved vigorously. A simple synthesis N-doped carbon nanotubes from recycled PET (NCNTsr-PET) was developed by a nitric acid-assisted hydrothermal method. Experimental results and theoretical calculations show the intrinsic defects in CNTsr-P...

In this work, ternary polymer blends based on polypropylene (PP)/ polyethylene terephthalate (PET) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (SEBS) triblock copolymer and a reactive maleic anhydride grafted SEBS (SEBS-g-MAH) at various compositions were prepared by co-rotating twin screw extruder. The effects of PET, SEBS and SEBS-g-MAH compatibilizer on morphology of the blends were ex...
