TLDR
In2O3:Sn (ITO) sols made of crystalline nanoparticles fully redispersable in an ethanol solution containing hydrolyzed organosilanes have been developed to get thick conducting transparent and antiglare coatings on substrates which do not withstand high temperature such as plastics (PMMA, polycarbonate) and already processed glasses as discussed by the authors.Abstract:
In2O3:Sn (ITO) sols made of crystalline nanoparticles fully redispersable in an ethanol solution containing hydrolyzed organosilanes have been developed to get thick conducting transparent and antiglare coatings on substrates which do not withstand high temperature such as plastics (PMMA, polycarbonate) and already processed glasses. The coatings were deposited by spin, dip and spray coating processes and cured by UV irradiation and/or by a low temperature heat treatment ( T = 130 °C) in air and reducing atmosphere. Their electrical, optical, textural and mechanical properties are reported. Stable sheet resistance as low as 2 k Ω was obtained with a single 500 nm thick transparent layer. Antiglare-antistatic coatings exhibiting similar sheet resistance, a gloss of 60–70 GU, a clarity of 75–90% and an optical resolution > 8 lines/mm were obtained by a room temperature spraying process. The abrasion resistance of the transparent coatings is in agreement with DIN 58196 G10 – class 1, the adhesion with DIN 58196K2 (tape test) and the pencil hardness (ASTM D 3363-92a) is 1H.read more

TL;DR: In this article, a dispersoid having metal-oxygen bonds is obtained by mixing a metal compound having at least three hydrolyzable groups with at least 0.5 mole but less than 2 moles of water per mole of the metal compound in an organic solvent, in the absence of an acid, a base and/or a dispersion stabilizer.

Transparent conductive coatings of hot-pressed ITO nanoparticles on a plastic substrate
TL;DR: In this paper, a tin-doped indium oxide (ITO) nanoparticle coatings were prepared on plastic substrates via a hot-press method and the optimal conditions for pressure and temperature were determined to be 1000 kg/cm 2 and 120°C, respectively.
