Tittle:
Self-cleaning biocide coating
Summary:
An Italian university research team with expertise in new materials has developed an innovative biocide self-cleaning coating from inorganic compounds that can be used in automotive, domestic appliances and textile sectors.
The coating is characterized by an efficient and rapid action and long time durability.
The partners sought are industrial companies interested in technical cooperation agreement.
Description:
The technology is proposed by an Italian university research team with expertise in new materials. The research team has developed an innovative biocide self-cleaning coating.

The last frontiers in the fight against bacteria and fungi that are pathogenic for man or other animals are represented by the development of new and powerful disinfectant strategies based on traditional chemical compounds or functionalized coatings.
The former method is pollutant and might induce bacterial resistance. Therefore, a great attention is paid in the development of biocide coatings characterized by environmental sustainability and with low management costs.
The chemical linkage or the immobilization between inorganic - or organic bactericidal compounds, and the polymeric matrix characterize these coatings.
While organic compounds are seldom used for their cost and troublesome immobilization, the usage of inorganic compounds is increasingly emerging as alternative technology.
For example, the combination of silver ions and titanium dioxide are of utmost interest as they combine activity in both dark and lighten environment, the efficient and rapid action of the metal ions and the durability over longer time of exposure of titanium dioxide.
The proposed technology is based on nano-sized Titanium dioxide (TiO2) anatase and silver ion (Ag+) supported on ultra-porous nano-sized glass spheres incorporated in organic and organic - inorganic hybrid resins.

The technique involves the dispersion of the inorganic fillers inside a number of solvent or waterborne thermosetting resins by shear mixing and addition of surfactants.
The final result is a homogenous suspension of the biocide principles (the nano-fillers) inside a variety of resins, which might be then deposited on the surface to protect by spraying or other conventional deposition techniques.

The research team is looking for industrial companies active in automotive, domestic appliances and textile sectors interested in self-cleaning coating. The type of partnership considered is technical cooperation agreement.
Advantages and Innovations:
The coating is self-cleaning according to standardized testing procedure.
The combination of titanium dioxide and silver ions permits the coating use in both dark and lighten environment.
The coating is characterized by long time durability. It is eco-friendly and the environmental sustainability is ensured.
The management costs are particularly low.
