Abstract:
The invention relates to a process for preparing a dichromatic material, in the form of a translucent film, comprising monodisperse nanoparticles formed of gold and optionally of a noble metal chosen from platinum, palladium, silver and copper, and at least one organic macromolecule chosen from proteins, polysaccharides and synthetic polymers; said dichromatic material; and the uses thereof.

Claim (Index 1):
Process for preparing a dichromatic material in the form of a translucent film, said dichromatic material comprising monodisperse nanoparticles formed of gold and optionally of a noble metal chosen from platinum, palladium, silver and copper (NPs), and at least one organic macromolecule chosen from proteins, polysaccharides and synthetic polymers, said process comprising the following steps:\n i) a step of mixing at least one organic macromolecule chosen from proteins, polysaccharides and synthetic polymers with a colloidal suspension S 0  of NPs, and ii) a step of drying the mixture from step i), in order to form a dichromatic material in the form of a translucent film deposited on a support,\n the NPs are in spherical form and have a diameter ranging from 70 to 100 nm, \n the molar concentration of gold in the mixture from step i) ranges from 10 \u22124  to 5\u00d710 \u22121  mol/l, \n the molar concentration of macromolecule in the mixture from step i) ranges from 0.001 to 5 mol/l, \n the film has a volume density ranging from 0.5\u00d710 10  to 5.0\u00d710 10  NPs/cm 3  for a  1  mm film thickness E, and \n said material has two complementary colours distinct to the naked eye, one colour in transmission and one colour in backscattering.
