Low-resistivity indium tin oxide [ITO] film was successfully deposited on oxygen plasma-treated polyethylene terephthalate [PET] surfaces at room temperature. X-ray diffraction [XRD] measurements demonstrated that the film deposited on the PET surface that had not been treated with oxygen plasma had an amorphous structure. In contrast, after the low-power oxygen plasma treatment of the PET surf...

Soil fumigation in greenhouses or agricultural fields often includes tarping the soil surface with polyethylene (PE) films to contain the fumigant in the soil and reduce emissions to the atmosphere. Previous research has demonstrated that PE films are permeable to methyl bromide and other fumigant compounds. In these experiments, the effect of temperature, fumigant mixtures, condensed water, an...

Amorphous indium–gallium–zinc-oxide (a-IGZO) thin films were deposited using RF magnetron sputtering on polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) flexible substrates and their mechanical flexibility investigated using uniaxial tensile and buckling tests coupled with in situ optical microscopy. The uniaxial fragmentation test demonstrated that the crack onset strain of ...

this study was conducted to evaluate the effect of high co2 modified atmosphere packaging (map) on storage quality of ‘selva’ strawberry fruits. the statistical analysis carried out using factorial experiment by completely randomized design (crd) with three replications. treatments included cover in two levels (polyethylene and polyamide) and two different gas compositions (2% o2 + 15% co2 + 83...

AIM To compare the efficacy for preventing exposure keratopathy of three forms of eye care (artificial tear, moist chamber and polyethylene covers) for intensive care patients. METHODS Eighty-four patients in Intensive Care Unit (ICU) were randomized to three treatment groups, including artificial tears group, moist chambers group and polyethylene film group. Patients of artificial tear group...

A novel nanocomposite polyvinyl alcohol precursor-based material dispersed with the web of carbon microfibers and carbon nanofibers is developed as lithium (Li)-ion electrolyte battery separator. The primary synthesis steps of the separator material consist of esterification of polyvinyl acetate to produce polyvinyl alcohol gel, ball-milling of the surfactant dispersed carbon micro-nanofibers, ...

barbari is a common iranian flat bread that has a short shelf life. the effect of low density polyethylene/clay nanocomposite film was investigated for the package and shelf life of the flat bread when stored at different temperatures and relative humilities with different percentages of nanoparticles. nanoclay concentrations of 2% and 6% were used for the nanocomposite and pure polyethylene wa...

Introduction Thin and ultrathin crystalline polymer films are of fundamental scientific and practical interest, e.g. in terms of their mechanical properties or of crystallization in a confined environment. A common route to ultrathin crystalline polymer films is spin-coating from solution, often at high temperature, which involves formation of crystalline structures during solvent evaporation. ...

A functional anticoagulant and anti-bacterial coating for polyethylene (PE) films is described. The stepwise preparation of this nanocomposite surface coating involves O2 plasma etching of PE film, carbodiimide coupling of cysteamine to the etched PE film, binding of Ag to sulfhydryl groups of cysteamine, and assembly of heparin capped AgNPs on the PE film. The nanocomposite film and its compon...
