What are carbon nanotubes?
Carbon nanotubes (CNTs) are cylindrical molecules made up of rolled sheets of single layer carbon atoms (graphene). They can be single wall (SWCNT) with a diameter of less than 1 nanometer (nm) or multiple wall (MWCNT), consisting of several concentrically interconnected nanotubes, with diameters reaching more than 100 nm. Their length can reach several micrometers or even millimeters. CNTs are chemically linked with sp2 type orbit hybridizations, an extremely strong form of molecular interaction. This feature combined with the natural inclination of carbon nanotubes to bond together through the van der Waals forces, provide the opportunity to develop ultra-resistant and low weight materials that possess highly conductive electrical and thermal properties. This makes them functional for numerous applications and different industrial sectors such as textiles, making fabrics from antistatic to conductive, the ceramic sector, for example by increasing the heat conduction in an indoor environment and obtaining a climate with high emergetic savings, in the sector plastic to produce resistant and antistatic films.
The difficulty in obtaining a product with high dispersion and adhesion power was our goal. The commercially available aqueous solutions have a low shelf life (3 months) and usually precipitate or separate after this period. R-CNTS is an aqueous solution stable over time or an amorphous colloidal nanotube with very strong adhesion powers on any type of substrate. We doped the carbon nanotubes with a colloidal photocatalytic solution based on titanium dioxide and the result was incredible. Very high adhesion to the substrate, hydrophilicity, self-cleaning of the surface. With 30g. of product per m2 we are able to obtain a conductivity of 10 ^ 3. If the substrate is rigid, for example a tile, it becomes hydrophilic. If heated to 250 ° C, the layer becomes very hard. It is applied by spray with the HVLP system or by dip-coating. It lasts at least 10 years. Produced in Italy.
Static electricity is the superficial accumulation of electric charges on a body made up of insulating material. This accumulation generally takes place by electrification by rubbing materials, especially in a dry environment. When two materials are separated, an electron transfer takes place from the surface atoms. The electron imbalance caused is the common electrostatic charge. The charges that have accumulated on people, systems or products, if not dispersed, can cause serious damage such as fire, electric shock, injury.
