Ces derniers ont montr\u00e9 qu&rsquo;il \u00e9tait suffisamment conducteur pour pr\u00e9senter de faibles r\u00e9sistances \u00e9lectriques, m\u00eame \u00e0 des \u00e9paisseurs extr\u00eamement r\u00e9duites lui permettant de laisser passer la lumi\u00e8re.<\/p>\n<p>Outre sa transparence et sa bonne conductivit\u00e9, ce film pr\u00e9sente l&rsquo;avantage d&rsquo;\u00eatre flexible et facile \u00e0 mettre en \u0153uvre sur des grandes surfaces, \u00e0 bas co\u00fbt, par diff\u00e9rents proc\u00e9d\u00e9s (spray, trempage, \u00e9coulement, impression). Lorsque ces films transparents sont soumis \u00e0 une tension de 12 V, la temp\u00e9rature du film peut d\u00e9passer 120\u00b0C, ce qui est parfaitement adapt\u00e9 pour des applications de d\u00e9givrage et de d\u00e9sembuage. Ainsi, ils ont mis au point, pour la premi\u00e8re fois, un film chauffant transparent, enti\u00e8rement r\u00e9alis\u00e9 \u00e0 base de polym\u00e8re.<\/p>\n<p>Un prototype de visi\u00e8re de moto a \u00e9t\u00e9 r\u00e9alis\u00e9 pour d\u00e9montrer l&rsquo;int\u00e9r\u00eat et la faisabilit\u00e9 du concept, suscitant l&rsquo;int\u00e9r\u00eat de plusieurs industriels. Une th\u00e8se va commencer pour am\u00e9liorer la conduction \u00e9lectrique et surtout, l&rsquo;\u00e9tirabilit\u00e9 du mat\u00e9riau. En attendant, trois brevets ont \u00e9t\u00e9 d\u00e9pos\u00e9s par le Liten pour prot\u00e9ger cette innovation prometteuse.<\/p>\n<p><a href=\"http:\/\/liten.cea.fr\/cea-tech\/liten\">CEA-Tech-Liten<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u200bLe\u00a0CEA a brevet\u00e9 le tout premier film chauffant\u00a0transparent 100% polym\u00e8re.
