Remote atmospheric-pressure plasma activation of the surfaces of polyethylene terephthalate and polyethylene naphthalate.

Evaluation of the Migration of Antimony from Polyethylene Terephthalate (PET) Plastic Used for Verjuice and Lemon Juice Packaging

The migration of antimony (Sb) from polyethylene terephthalate (PET) bottling for acidic juices have been assessed in this study. Inductively coupled plasma mass spectrometric (ICP-MS) method was chosen for antimony content determination. Experiments were undertaken at different conditions (15, 25, 35, 45days at 25, 50°C for first use bottle, reused bottle). Two different acidic juices (lemon j...

Modeling and cost minimization of weigh reduction of a polyethylene terephthalate fabric bu sodium hydroxide

Studying the Adsorption Behavior of a Disperse Dye on Polyethylene Terephthalate in Absence and Presence of a Nanostructured Hyperbranched Polymer

Dyeing properties of compounded polyethylene terephthalate fibers with a polyesteramide hyperbranched polymer were investigated in terms of their thermodynamic parameters, including standard affinity -Δμ⁰, enthalpy change ΔH⁰ and entropy change ΔS⁰. Results were then compared with corresponding properties of the virgin PET. The results showed that the isotherms were similar to that of virgin PE...

Implementation of line-scan dispersive interferometry for defect detection

Surface assurance is one of the main concerns for advanced manufacturing technologies such as Roll-to-Roll (R2R) technique. The undesired defects present on the barrier films make R2R products suffer from a low efficiency and short life span. In order to enhance the performance and the yield of the products, an inspection system enabling in-line metrology of functional surfaces in production li...

THz-conductivity of CVD graphene on different substrates

Optoelectronic properties of CVD graphene are characterized over a wide frequency range: THz, IR, visible and near-UV. We used Raman spectroscopy to characterize the synthesized graphene films. All graphene layers were deposited on various substrates, some ones transparent or flexible, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), quartz and silicon. Transmission Ter...
