Inkjet-printed chemical solution Y₂O₃ layers for planarization of technical substrates
The implementation of the Chemical Solution Deposition (CSD) methodology with 23 the Drop on Demand (DoD) inkjet printing (IJP) technology has been successfully employed to 24 develop a Solution Deposition Planarization (SDP) method. We have used nanocrystalline yttrium 25 oxide (Y₂O₃) to decrease t...

The implementation of the Chemical Solution Deposition (CSD) methodology with 23 the Drop on Demand (DoD) inkjet printing (IJP) technology has been successfully employed to 24 develop a Solution Deposition Planarization (SDP) method. We have used nanocrystalline yttrium 25 oxide (Y₂O₃) to decrease the roughness of technical metallic substrates by filling the surface 26 imperfections and thus avoiding costly polishing steps. This alternative process represents an 27 outstanding methodology to reduce the final cost of the 2G coated conductors manufacturing. 28 Two Y₂O₃ metalorganic precursor inks formulations were successfully developed and tested to 29 obtain surfaces as smooth as possible with adequate mechanical properties to hold the internal 30 stresses developed during the subsequent layers growth. 31 By using these inks as precursors for IJP and after a proper tuning of the rheological and 32 wetting parameters, we firstly obtained short length uniform 100nm-thick Y₂O₃-SDP films on 33 unpolished stainless steel substrate from Bruker HTS.
