Title (EN) PROCESS FOR THE PREPARATION OF CARBON FIBERS PRECURSOR OR CARBON SLIT TAPES PRECURSOR
(FR) PROCÉDÉ DE PRÉPARATION DE PRÉCURSEUR DE FIBRE DE CARBONE OU DE PRÉCURSEUR DE BANDELETTES DÉCOUPÉES EN CARBONE
Abstract:
(EN) The present invention relates to a process for the preparation of a carbon fiber precursor or a carbon slit tape precursor, comprising the steps of: a) mixing at least one polyolefin or at least one polystyrene, with at least one additive (a1) selected from the group comprising carbon nanotubes, carbon fibers, carbon black, graphene, nanographene, graphite, expanded graphite, nanographite, fullerenes, and mixture thereof; and/or or at least one additive (a2) selected from the group comprising calcium carbonate, sodium carbonate, lithium carbonate, sodium bicarbonate, potassium bicarbonate, magnesium carbonate, alumina, hydrated alumina, magnesia, silicon aluminum oxynitride, borosilicate, silicon carbide, boron carbide, titanium carbide, boron nitride, boron nitride nanotubes, boron nitride nanosheets, silicon nitride, aluminum nitride, titanium nitride, titanium diboride, aluminum dodecaboride, diatomite, feldspar, gypsum, hormite, kaolin, mica, nepheline syenite, perlite, phyrophyllite, smectite, talc, vermiculite, zeolite, calcite, wollastonite, calcium metasilicate, calcium sulfate, aluminum silicate, silicon dioxide, titanium dioxide, clay (such as kaolinitic clay, a calcined kaolinitic clay, exfoliated clay), dolomite, and mixtures of two or more thereof; b) forming the mixture obtained in step (a) into a fiber or a slit tape having at least one dimension ranging from 500 nm to 200 μm; and c) subjecting the fiber or slit tape obtained in step (b) to a thermal treatment in the presence of at least one inorganic acid; thereby obtaining a carbon fiber precursor or a carbon slit tape precursor. The present invention also relates to the carbon fiber precursor or carbon slit tape precursor obtained with said process. The present invention also relates to a process for preparing carbon fibers or slit tapes by thermal graphitization treatment of said carbon fiber precursor or slit tape precursor.
(FR) La présente invention concerne un procédé de préparation d'un précurseur de fibre de carbone ou d'un précurseur de bandelette découpée de fibre de carbone, comprenant les étapes consistant à : a) mélanger au moins une polyoléfine ou au moins un polystyrène, avec au moins un additif (a1) choisi dans le groupe comprenant les nanotubes de carbone, les fibres de carbone, le noir de carbone, le graphène, le nanographène, le graphite, le graphite expansé, le nanographite, les fullerènes, et un mélange de ceux-ci; et/ou au moins un additif (a2) choisi dans le groupe comprenant le carbonate de calcium, le carbonate de sodium, le carbonate de lithium, le bicarbonate de sodium, le bicarbonate de potassium, le carbonate de magnésium, l'alumine, l'alumine hydratée, la magnésie, l'oxynitrure de silicium aluminium, le borosilicate, le carbure de silicium, le carbure de titane, le nitrure de bore, les nanotubes de nitrure de bore, les nanofeuilles de nitrure de bore, le nitrure de silicium, le nitrure d'aluminium, le nitrure de titane, le diborure de titane, le dodécaborure d'aluminium, la diatomite, le feldspath, le gypse, l'hormite, le kaolin, le mica, la syénite néphélinique, la perlite, la phyrophylllite, la smectite, le talc, la vermiculite, la zéolite, la calcite, la wollastonite, le métasilicate de calcium, le sulfate de calcium, le silicate d'aluminium, le dioxyde de silicium, le dioxyde de titane, l'argile (telle que l'argile kaolinitique, l'argile kaolinitique calcinée, l'argile exfoliée), la dolomite et des mélanges de deux ou plus de deux de ceux-ci; b) former le mélange obtenu à l'étape (a) en une fibre ou une bandelette découpée ayant au moins une dimension allant de 500 nm à 200 µm; et c) soumettre la fibre ou bandelette découpée obtenue à l'étape (b) à un traitement thermique en présence d'au moins un acide inorganique; ce qui permet d'obtenir un précurseur de fibre de carbone ou un précurseur de bandelette découpée de carbone. La présente invention concerne également le précurseur de fibre de carbone ou le précurseur de bandelette découpée en carbone obtenu avec ledit procédé. La présente invention concerne également un procédé de préparation de fibres de carbone ou de bandelettes découpées, par traitement de graphitisation thermique dudit précurseur de fibre de carbone ou dudit précurseur de bandelette découpée.
