    摘要: The invention relates to a method for the production of composite fibers with an increased content of colloidal particles, made from a pre-fiber, comprising a polymeric binder and colloidal particles, during which the chemical structure of the polymeric binder is degraded at a temperature of the order of ambient temperature such as to at least partially eliminate the above. The invention further relates to a fiber comprising a polymeric binder and colloidal particles, combining an excellent mechanical strength and a content of colloidal particles greater than 70% by mass.

    摘要: The invention relates to a method for obtaining composite fibers, that comprises dispersing colloidal particles in a solvent, injecting the dispersion into a co-flow of a polymer coagulation solution for forming a pre-fiber, circulating the pre-fiber in a duct, extracting, optionally washing and drying the pre-fiber in order to obtain a fiber, and winding the fiber thus obtained, characterized in that the minimum retention time of the fiber within the duct is adjusted so that it has a mechanical strength sufficient to be extracted from the duct, and in that its extraction is vertical and continuous. The invention also relates to composite fibers that can be made according to said method.

    摘要: The invention concerns a method for obtaining fibers and strips from colloidal particles, characterized in that it consists in: 1) dispersing said particles in a solvent optionally using a surfactant; 2) injecting the resulting dispersion solution through at least an orifice emerging into a flow of an external solution, preferably, having a higher viscosity than said dispersion, the viscosity levels being measured in the same temperature and pressure conditions, so as to cause said particles to agglomerate into fibers or strips by destabilizing the particle dispersions and optionally aligning said particles.

    摘要: A method of manufacturing composite fibers comprising two distinct layers having different compositions and physico-chemical properties and controlled, homogenous thicknesses, wherein one of two layers comprises carbon nanotubes and the composite fibers are obtained from carbon nanotube fibers and a first solution of a selected concentration of colloidal particles intended to constitute the second layer, comprising the following steps: placing the fibers in contact, by lateral surfaces thereof, with a surface of a second solution which is adapted to chemically cause aggregation of the colloidal particles and is completely or partially immersed in the second solution, the immersed thickness of the fibers defining the immersion area, placing the thus pre-coated fibers in contract, on the same lateral surface, with a surface of the first colloidal particle solution and immersed in it at most up to the immersion area to locally form a colloidal gel with a fixed thickness determined by the concentration of the first solution, separating the fibers covered in the first solution, and drying and/or evaporating the solvent of the first solution.
