In this work are reported efforts made about the development of an inkjet deposition system for inks based on water solutions of multiwalled carbon nanotubes (MWCNT) and poly(methacrylic acid) (PMA). The core of the deposition system consisted of an HP720 printer head, modified to allow the printing of inks on different substrate typologies. The developed system has been employed in the deposition of MWCNTs/PMA contacts on glossy papers and PET transparency sheet for flexible electronics. By varying the printing cycles (i.e. performing an overprinting) it was possible to modulate the thickness of the printed film. The deposition of Agdoped MWCNT/PMA films on alumina-based sensor substrates was also investigated with the aim to fabricate sensor devices for practical applications.

Abstract
In this work are reported efforts made about the development of an inkjet deposition system for inks based on water solutions of multiwalled carbon nanotubes (MWCNT) and poly(methacrylic acid) (PMA). The core of the deposition system consisted of an HP720 printer head, modified to allow the printing of inks on different substrate typologies. The developed system has been employed in the deposition of MWCNTs/PMA contacts on glossy papers and PET transparency sheet for flexible electronics. By varying the printing cycles (i.e. performing an overprinting) it was possible to modulate the thickness of the printed film. The deposition of Agdoped MWCNT/PMA films on alumina-based sensor substrates was also investigated with the aim to fabricate sensor devices for practical applications.Pubblicazioni consigliate
