Title
(EN) SEBUM RESISTANCE ENHANCEMENT FOR WEARABLE DEVICES
(FR) AMÉLIORATION DE LA RÉSISTANCE AU SÉBUM DE DISPOSITIFS PORTATIFS
Abstract
(EN)
A method of treating a wearable device to resist sebum, the method including providing a body having an elastic material having a polymeric backbone where a portion of the polymeric backbone is unsaturated and the body has an outer surface. The method further includes forming a crosslinked matrix within an outer layer of the body surrounding an inner layer of the body such that the outer layer has less affinity to sebum than the inner layer of the body.
(FR)
L'invention concerne un procédé de traitement d'un dispositif portatif destiné à résister au sébum, le procédé consistant à fournir un corps présentant un matériau élastique présentant un squelette polymère, une partie du squelette polymère étant insaturée et le corps présentant une surface externe. Le procédé consiste en outre à former une matrice réticulée au sein d'une couche externe du corps entourant une couche interne du corps, de telle sorte que la couche externe présente moins d'affinité pour le sébum que la couche interne du corps.
