With the rapid economic development, electronics, chemicals, textiles, machine room, static electricity problems in packaging and other industries have attracted wide attention. Conductive filler can eliminate the matrix materials, such as plastics, coatings, chemical fiber, rubber, ceramic tile is the main method of static electricity, by on the principle of conductive filler in the insulating substrate forming a conductive network charge to reach the matrix release purposes. Commonly used include permanently conductive filler metal powder, carbon, oxides, and so on. To reduce costs or improve existing in conductive fillers fillers chroma can be chemically heterogeneous nucleation theory in some white powder coating formation of Antimony Doped Tin Oxide composite conductive powder. Due to the conductive path formed in the substrate is a prerequisite for eliminating static electricity, so using high aspect ratio materials, such as conductive carbon nanotubes, carbon fiber, conductive metal fibers (stainless, nickel fiber, etc), needle-shaped titanium dioxide coated ATO, can reduce the amount of conductive material, thereby reducing production costs.
Antimony Doped Tin Oxide coating should first consider its dispersion in the paint, though Antimony Doped Tin Oxide compared to have better dispersion of metal powders, but due to its high surface energy of nanometer powder made prevailing in its powder agglomeration, increase of the dispersion degree of difficulty. This years of slow progress in the application of nano-ATO conductive powder are the main reasons. Of nanometer ATO powder by dispersing and anti-static application data show that, with the decrease of slurry particle size of nano-ATO particles in, that are required to achieve the same anti-static effect of nanometer ATO powder dosage reduced, reduce operating costs, while mechanical and optical properties of materials have also been improved.
Its good insulating properties, is widely used in the coatings, chemical fibre, polymer film and other fields. In addition as a conductive materials, dispersion, activity, thermoplastic-resistance, abrasion resistance, security with other conductive material (such as graphite, surfactants, such as metal powders), incomparable advantages. Is used in optoelectronic display, transparent electrode, solar cell and LCD, catalytic, and so on.
Antimony Doped Tin Oxide powders and conductive material offers significant advantages over traditional, in transparent, conductive, anti-static, infrared blocking and other fields, has broad application prospects. But in electro-optical mechanism of Antimony Doped Tin Oxide powders, Nano-ATO powder application and secondary development of nanometer ATO powders and other aspects to be further studied.
