Title (EN) POLYANILINE COMPOSITIONS, PROCESS FOR THEIR PREPARATION AND USES THEREOF
(FR) COMPOSITIONS DE POLYANILINE, LEUR PROCEDE DE PREPARATION ET LEURS EMPLOIS
Abstract:
(EN) Self-protonated sulfonic acid substituted polyaniline compositions, processes for their preparation and uses thereof. The sulfonated polyaniline compositions are useful for conduction of electricity, absorption of electromagnetic radiation, modulation of electromagnetic beams and modification of the electromagnetic response of sulfonated polyaniline compositions by chemical or electrochemical means. The sulfonated polyaniline compositions are also useful as a high density erasable data storage medium for use in information storage and process applications. The sulfonated polyaniline compositions provide electronic, chemical, electrochemical and optionally microelectronic devices which use and control the chemical and physical properties of the compositions.
(FR) Compositions de polyaniline à substitution d'acide sulfonique à auto-protonation, leurs procédés de préparation et leurs emplois. Les compositions de polyaniline sulfonée sont utiles dans la conduction d'électricité, l'absorption de rayonnement électromagnétique, la modulation de faisceaux électromagnétiques et la modification de la réponse électromagnétique de compositions de polyaniline sulfonée à l'aide d'un moyen chimique ou électrochimique. Les compositions de polyaniline sulfonée sont également utiles en tant que moyen de stockage de données effaçables de haute densité, utilisé dans le stockage d'informations et dans des applications de traitement. Les compositions de polyaniline sulfonée permettent d'obtenir des dispositifs électroniques, chimiques, électrochimiques et facultativement micro-électroniques, lesquels utilisent et régulent les propriétés chimiques et physiques des compositions.
