Thin silicon oxide (SiOx) barrier coatings formed by plasma enhanced chemical vapor deposition on poly(ethylene terephthalate) (PET) substrates were subjected to post-deposition annealing treatments in the temperature range for orientation relaxation of th ...
The mechanical properties of ultrathin silicon oxide (SiOx ) coatings plasma-deposited on poly(ethylene terephthalate) (PET) films were investigated with particular attention paid to the effect of additives located in the superficial layers of the polymer ...
Ultra-thin (10–500 nm) photo-polymerized γ-methacryloxypropyltriethoxysilane (MPMS) and vinyltrimethoxysilane (VTS) layers applied to SiO2 coatings on polyethylene terephthalate films improved the oxygen barrier performance of the oxide coated films by mor ...
Uniaxial fragmentation tests were carried out in situ in a scanning electron microscope (SEM) on 10-nm-thick silicon oxide coatings deposited by plasma enhanced chemical vapor deposition on poly(ethylene terephthalate). In order to prevent charging effects ...
The oxygen transmission rate of 48 nm thick SiO2 coatings on a poly(ethylene terephthalate) (PET) substrate was reduced by a factor of three after applying an 8 nm thick layer of oligomerized gammaaminopropyltriethoxysilane (γ-APS). Increasing the thicknes ...
The influence of the surface morphology of semi-crystalline poly(ethylene terephthalate) (PET) and polyamide 12 (PA12) films on the adhesion and cohesion of thin oxide coatings is analysed, with attention paid to the role of spherulites and processing addi ...
The aim of this study is to develop coatings on polymer substrates with a combined increase in oxygen barrier performance and toughness, based on SiOx coatings modified with multifunctional organo-silane polymers of controlled polarity and reactivity. As a ...
The present work analyses silicon oxide coated polyester films, with attention paid to the effect of substrate process additives on the coating defect population, and on the coated film mechanical properties. The defect population is characterized by means ...
Aminosilane solutions with pH equal to 8 and to 11 were applied and cured on SiO2 coated poly(ethylene terephthalate) (PET) films. The permeability of the silane-silica hybrid coating on PET was reduced twofold compared to that of the SiO2/PET film, at sol ...
The influence of the surface morphology of semicrystalline polyamide 12 PA12! on the adhesion of thin silicon oxide coatings is analyzed by means of uniaxial fragmentation tests and scanning local-acceleration microscopy SLAM!. Two types of PA12 substrates ...
