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...
متن کاملConfinement-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 ...
متن کاملPolyethylene 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...
متن کاملPerformance evaluation of cutting fluids additives developed from recycling of polyethylene terephthalate
Metalworking-fluids (MWFs) perform essential functions to metal-products manufacturing industry. MWFs also have inherent environmental and health liabilities associated to industry. These liabilities viewed as opportunity to reevaluate the functionality of MWFs and improve profitability of operations. Several problems appeared in using of MWFs including biodegradation of constituents. The objec...
متن کاملQuantitative evaluation of radiation damage to polyethylene terephthalate by soft X-rays and high-energy electrons.
The chemical changes and absolute rates in radiation damage to polyethylene terephthalate (PET) caused by soft X-rays and energetic electrons have been measured using a scanning transmission X-ray microscope (STXM). Electron beam damage at two different dose rates and a range of doses was performed in an 80 keV transmission electron microscope (TEM). The STXM beam was used to create damage patt...
