Abstract: The invention relates to a coating based on a fluoro acrylate polymer latex comprising inorganic particles, said coating exhibiting a very good compromise between, on the one hand, dry adhesion and adhesion in the wet state, and, on the other hand, between adhesion and ionic conductivity. This coating is intended for a separator application, in particular for Li-ion batteries. The invention also relates to a Li-ion battery comprising a separator covered with such a coating.

Abstract: This invention pertains to the area of orthodontic apparatuses, particularly those that have been precisely adapted to the specific morphology of each patient. The invention proposes a preform dissimilar to a plate; the form of which allows it to expand within a mold that reproduces a patient's morphology; it may be mass produced and easily adapted by the practitioner or prosthesis maker to each patient's morphology as well as orthodontic or dento-facial orthopedic apparatuses obtained from this preform and their manufacture process. Such apparatuses are, for example, Bonnet's N.L.E. (Nighttime Lingual Envelopes—Enveloppe Linguale Nocturne) or any apparatus presenting a general hollow body form, possibly with one or more openings, varying thickness, and which, because of this specific geometry, cannot be produced from a model in the form of a flat plate.
