1. Stradal, Milos. Surface treatment of polyethylene in electrical discharges.

Degree: PhD, Department of Chemistry, 1974, McGill University

Note:

Corona treatment in oxygen, nitrogen, helium and argon substantially enhanced the autohesion of low density polyethylene. The power consumed rather than the nature of the gas in the discharge proved to be the important variable controlling the increase in the autohesion. Corona-induced oxidation of polyethylene had a detrimental effect upon bonding. Increase in polymer density and surface roughness lowered the autohesion. The temperature dependence of bonding for both rough and smooth surfaces, either untreated or treated, was similar to the temperature dependence of viscous flow of polyethylene. The rates of decay on aging of surface charge and capacity for autohesion of corona treated polyethylene followed similar trends, increasing with increase in the temperature of storage. However it was shown that the corona-induced autohesion was not due to the presence of surface charge. Corona-induced oxidation of polyethylene was not a prerequisite for the good bonding of printing ink to the surface of the plastic.

Le traitement par corona dans l'oxygène, l'azote, l'hélium et l'argon ont augmenté d'une manière substantielle l'autoadhésion du polyéthylène de faible densité. Il a été démontre que la puissance consommée plutôt que la nature dugaz dans la décharge est le facteur important qui contrôle l'augmentation d'autoadhésion. L'oxydation du polyéthylène induite par corona avait un effet nuisible sur la liaison. L'augmentation de densité du polymère et de la rugosité de la surface ont diminué l'autoadhésion. La dépendance de la liaison a la température pour des surfaces rugueuses et lisses, traitées ou non-traitées, allait de pair avec la dépendance de la température du flux visqueux du polyéthylène. Les vitesses de décroissance de la charge de surface et de la capacité après vieillissement pour l'autoadhésion du polyéthylène traite par corona ont montré des tendances similaires, augmentant avec l'augmentation de température de stockage. Néanmoins, Il a été prouvé que l'autoadhésion induite par corona n'était pas due à la présence de la charge de surface. L'oxydation du polyéthylène induite par corona n'était pas nécessaire a la bonne liaison de l'encre d'imprimerie a la surface du plastique.
