Antistatic coatings for wood-floorings by imidazolium salt-based ionic liquids

The tendency to electrostatic charge is at least an unpleasant property, which is unfortunately typical for many floors. Ionic liquids represent a good alternative to overcome the disadvantages from typical antistatic agents like worse leaching behavior and at least haze in the coating. 1-Allyl-3-alkyllimidazolium salts have been evaluated as antistatic additives in a UV-curing coating for parquet flooring. 1-Allyl-3-methyllimidazolium chloride has been identified to exhibit the highest activity and a minimized leaching. The measured body voltage regarding EN 1815 was below ≤2.0 kV and the resistivity regarding EN 1081 below 10¹⁰ Ω. In addition, there is a synergistic effect with conductive and transparent indium-tin-oxide pigment particles.

Colloidal indium tin oxide nanoparticles for transparent and conductive films

Nanosized colloidal indium tin oxide (ITO) dispersion was prepared for electrically conductive and transparent coating materials. A titanate coupling agent, isopropyl tri(N-ethylenediamino)ethyl titanate, was chosen as a dispersant for the stabilization of ITO nanoparticles in organic solvent. ITO sol was deposited on a cathode ray tube panel for antistatic or electromagnetic shielding purposes, and alkyl silicate was used for the formation of an antireflective over-coat layer. The resulting double-layered coating showed low sheet resistance, which satisfied semi-TCO regulation and low reflectance of visible light. To control the electrical and optical properties of the coating layer, the effects of secondary particle size of ITO aggregates and the dispersant concentration of ITO sol were studied. The stability of ITO sol was estimated by measuring the particle size as a function of the storage days and the aggregation of colloidal ITO dispersion with storage day was explained by depletion flocculation.
