Abstract
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.
