This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La société ESSILOR est à l'origine d'un nouveau concept ophtalmique : « l'optique digitale ». Ce concept s'appuie sur la discrétisation du verre en pixels et l'introduction, dans ces structures micrométriques, de liquides fonctionnels. Les axes de recherche de cette thèse sont issus des besoins et contraintes de cette thématique et ils concernent principalement : l'élaboration de couches minces polymères par un procédé CVD (Chemical Vapor Deposition) et les dépôts de films sur des substrats liquides. Un bâti commercial de CVD avec un mode d'activation thermique a permis la réalisation contrôlée et la caractérisation de couches minces conformes d'un matériau polymère aux propriétés en adéquation avec le cahier des charges industriel : le parylène. Des études sur le mécanisme mis en jeu ont révélé un mode de croissance original de ce matériau et pouvant être décrit par différents modèles complémentaires dans les informations qu'ils apportent. Nous avons également imaginé un dispositif de modulation des propriétés surfaciques des films de parylène par une fonctionnalisation en voie sèche. Le second procédé CVD qui a été étudié met en œuvre l'activation photonique. Il s'agit d'un bâti de photo-CVD innovant et très modulable, développé au CIRIMAT, pour répondre au mieux aux besoins de ce projet « verre digital » et en particulier à la nécessité de déposer des couches de divers polymères sur des liquides fonctionnels à une pression se rapprochant de la pression atmosphérique.
