Summary of the technology
This method has two stages:
1) Dispersion of, at least, an inorganic material in water.
2) Addition of, at least, an organic coloring solubilized by agitation.
The following parameters might be changed in order to obtain different kinds of nanopigments:
• Inorganic material concentration.
• Organic coloring concentration.
• Ionic strength.
The optical response of nanopigments changes as a function of the particle size of the inorganic material (or materials) used by the diffusion.
This method makes it possible to produce new hybrid nanopigments with optical and colloidal properties for tailored applications. Mainly, the customizaton of the behaviour of this materials is achieved by controlling organic/inorganic ratio in the material.
The morphology of the material is hybrid (laminar/fibrillar). The organic coloring is selected among different types: azoic complexes, metallic, sulphurose, iminoquinone, antraquinone, ftalocianine, etc. In general words, they can be both natural or synthetic.
Products can be used in printing inks, painting and dyes, paper, synthetic or natural fibers, polymer materials, cosmetics, etc.
With this method the following features can be achieved:
Color range control: Through the control over the different spectral species, the optical response is modified too, so the color range can be enlarged.
Increase in the colouring power: The ability of the material for increasing the absorption on the surface is linked to three parameters. First, absorption coefficient of the nanopigment in relation to the coloring solution coefficient. Second, light dispersion caused by nanoparticles and addtiional coverage of the surface to fill. Third, reology and fisico-chemical properties of the material are able to obtain homogeneous dispersions.
Environmental impact reduction: Some of the usual pigments contain heavy metals in its composition while inorganic solids used in this method are free of heavy metals and can even be used in cosmetics. Natural coloring can be combined with these nanopigments and obtain a new product which will be environmental safe.
Description of the technology
A hybrid pigment is a controlled mixture between inorganic and organic material. As inorganic material it could be used in several kinds of clays for their nanoscopic properties and, as organic material, natural or synthetic colorings (thermochrome, eletrochrome, luminescence, etc.). The research group has developed a new method to produce nanostructured hybrid pigments with specific optical and colloidal properties according to the production parameters. Mainly, the customizaton of the behaviour of this materials is achieved by controlling organic/inorganic ratio in the material.

Main advantages of its use
- The pigments produced by this method are very cheap.
- The production method is very easy. It usually works at room temperature (below 200ºC).
- These nanopigments provide a homogeneous coloration of the substrate.
- These nanopigments provide a wide range of intense colors which are stable to heat, ultraviolet radiation, oxygen and other environmental agents.
- Unlike conventional pigments, these nanopigments are heavy-metals free. Then, the developed colorings are non-toxic and environment friendly.
- Ceramic, cement and concrete.
- Food industry.
- Pharmaceutical products and cosmetics.
- Polymeric material and plastics.
- Synthetic and natural fibers.
