Stress controlled gas-barrier oxide coatings on semi-crystalline polymers
TL;DR: In this article, the effect of post-deposition annealing on the internal stress state of barrier coatings was measured by means of thermo-mechanical analyses, and its effect on the coating cohesive properties and polymer adhesion was determined from the analysis of uniaxial fragmentation tests in situ in a scanning electron microscope, assuming a Weibull-type probability of failure and a perfectly plastic stress transfer at the SiOx/PET interface.

Influence of substrate additives on the mechanical properties of ultrathin oxide coatings on poly(ethylene terephthalate)
TL;DR: In this paper, the effect of additives located in the superficial layers of the poly(ethylene terephthalate) (PET) substrate was investigated, and it was shown that the presence of additives led to a 20% decrease of the crack onset strain, which is due to an increase of the coating defect density.

TL;DR: In this paper, thin films were used for organic-inorganic hybrid coatings and a barrier system for thin films was proposed for thin-film thin-walled hybrid coating.

Influence of substrate morphology on the cohesion and adhesion of thin PECVD oxide films on semi‐crystalline polymers
TL;DR: In this article, 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 analyzed, with attention paid to the role of spherulites and processing additives.

Durability of aminosilane-silica hybrid gas-barrier coatings on polymers
TL;DR: Aminosilane solutions with pH equal to 8 and to 11 were applied and cured on SiO2 coated poly(ethylene terephthalate) (PET) films as mentioned in this paper.
