Abstract
The global conductive ink market size has been expected around a CAGR of 4.1%, by value and
the market is estimated to be USD 3.0 to 3.7 billion in 2020-2025. Indium tin oxide (ITO) ink is
used as conducting ink and in engineering applications. Therefore the review is aimed to provide
more insights into various reactants precursors, conditions, and synthesis procedure for the
development of ITO nano inks. The merits and demerits of the various methods such as
hydrothermal, solvothermal, spray pyrolysis, sol-gel, and electrophoretic deposition, magnetron
sputtering etc, used for making ITO nanoparticles were discussed in detail. Further, various ink
properties, parameters and processes for development of ITO nano ink proposed by different
research groups is also discussed. The suitable conditions to print the prepared ITO ink on
suitable substrate using ink-jet fabrication methodology discussed by various research groups
is also explored. Also, the review focusses on the study of the properties of the printed ink such
as transmittance and the sheet resistance is also studied. Finally the sensitivity, response and
recovery of the ITO coated electrode developed for various sensor applications is discussed in
detail.
