HEATING MEANS SENSITIVE TO ELECTROMAGNETIC RADIATION, BASED ON MOTT MATERIALS

摘要

The invention relates to heating means that allow optimal absorption of non-ionising electromagnetic radiation, the associated information or energy of which is transformed into heat. The subject matter of the invention consists of a composition and an architecture based on micro- and nano-particles that can resonate with the external radiation. Said particles, as radiation-sensitive entities, preferably comprise Mott materials. In terms of efficiency, particles of Mott materials must be dispersed in a spacer matrix, the maximum charge of which precisely determines the electrical percolation threshold of the nanocomposite. The invention can be used for selective heat generation, for catalytic activation or as a material that prevents the propagation of an electromagnetic signal.
