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.

Method for obtaining macroscopic fibres and strips from colloidal particles and in particular carbon nanotubes

The invention concerns a method for reforming composite fibres comprising colloidal particles and at least a binding and/or crosslinking polymer, characterised in that it comprises: means for deforming, by cold process at room temperature or at a temperature slightly higher than room temperature, said polymer of said fibre, and means for applying, on said fibre, mechanical stresses.
