Optimisation des paramètres d'impression pour l'électronique imprimée sur supports souples.

Abstract : Printed electronics takes place with the interface between the sectors of graphic industries and that of micro-electronics. The traditional industrial techniques of impression that are the gravure, the flexography and the offset have the great advantage of a higher productivity raised in terms of the produced surface. A stage of fundamental research, on the formulation of specific pigment inks or containing functional polymers, is placed in the middle of the problems. The work of this thesis falls under the context of printed electronic by the optimization of the various parameters intervening in the impression. Thus the rheology and the physico-chemistry of inks represent a capital objective that cannot be dissociated of the characterization step of the supports. Indeed each process of impression has its specificities in terms of inks properties. A good adequacy ink/support is obligatory in order to obtain an impression with the required characteristics.
We thus formulated various conducting polymeric inks in particular one containing poly (ethylene dioxythiophene) - poly (styrene sulphonate). A study of the properties of surface and physical characteristics of various papers and plastics was conducted and two media were chosen for our impressions. In addition, an optimization study of the impression parameters was carried out viewing to determine the influence of the impression conditions on the characteristics of the deposits layers, particularly of electric conduction. A state of the art and a bibliography research illustrate the projections of printed electronics, its applications and its challenges.
