Abstract
A method for preparing a colloid solution of titanium dioxide nanoparticles in a solution of acrylic resin in organic solvent includes mixing titanium dioxide nanoparticles with a solution of acrylic resin in organic solvent, so as to obtain the colloid solution. The colloid solution is subjected to a stabilization treatment suitable for preventing or reducing nanoparticle aggregation, the treatment includes irradiating the colloid solution with pulsed coherent light having a wavelength substantially comprised in the ultraviolet absorption band of the titanium dioxide nanoparticles.
