  1. 1. Metal Films for Printed Electronics : Ink-substrate Interactions and Sintering

    Author : Thomas Öhlund; Håkan Olin; Hans-Erik Nilsson; Mattias Andersson; Patrick Gane; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; NATURAL SCIENCES; inkjet printing; silver nanoparticles; paper; flexible substrates; sintering; printed electronics; IPL sintering; flash sintering; copper films; coatings; thin films; AgNP; conductive films; metal films;

    Abstract : A new manufacturing paradigm may lower the cost and environmental impact of existing products, as well as enable completely new products. Large scale, roll-to-roll manufacturing of flexible electronics and other functionality has great potential. READ MORE

  2. 2. Transparent Conductive Tin Doped Indium Oxide : Characterisation of Thin Films Made by Sputter Deposition with Silver Additive and by Spin Coating from Nanoparticle Dispersions
