Poly(ethylene terephthalate) Film Recycling

Confinement-induced vitrification in polyethylene terephthalate

Dynamic mechanical thermal analysis performed on cold-drawn polyethylene terephthalate PET , cold crystallized annealed in the temperature interval 100–140 °C, reveals the presence of marginally glassy domains above the annealing temperature Ta. This suggests that the thermodynamic force driving crystallization causes the structural arrest of some noncrystalline domains. The latter thus need a ...

Polyethylene Terephthalate May Yield Endocrine Disruptors

BACKGROUND Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. OBJECTIVE I begin by considering evidence that bottles made fr...

Immobilization of silver nanoparticles on polyethylene terephthalate

Two different procedures of grafting with silver nanoparticles (AgNP) of polyethylene terephthalate (PET), activated by plasma treatment, are studied. In the first procedure, the PET foil was grafted with biphenyl-4,4'-dithiol and subsequently with silver nanoparticles. In the second one, the PET foil was grafted with silver nanoparticles previously coated with the same dithiol. X-ray photoelec...

Chemical Recycling of Poly Ethylene Terephthalate Wastes

Chemical recycling of Polyethylene terephthalate, PET, wastage has been investigated in this study. The aim of this work is recovery of terephthalic acid and ethylene glycols from PET waste. This process has been done in two stages. At the first stage, reaction between PET waste and sodium hydroxide for production of ethylene glycol and sodium terephthalate solution carried out in a stainless s...
