New Printed Electronics Material Breakthroughs at Asia event
Cambridge, UK — IDTechEx's Printed Electronics Asia event, will take place on October 2-3 at the Hilton Tokyo, in Tokyo, Japan. New material breakthroughs for the printed and large area electronics industry will be one of the main topics.
We are witnessing a rapid multiplication of available conductive materials for printed and large area electronics on the market. The different materials distinguish themselves by their conductivity, particle size, curing conditions, availability and cost.
Conductive inks are a simple and unglamorous layer but they will constitute a hefty $2.86 billion market in 2012. According to IDTechEx research, this market is forecast to rise to $3.36 billion in 2018, with $735 million captured by new silver and copper nanostructure inks. These sales, taken from the Conductive Ink Markets 2012-2018 report, make conductive inks the most successful segment of all printed electronics, surpassing printable OLEDs, photovoltaics, and displays.
Compared to silver-based materials, copper is a low-cost option and offers high conductivity in its bulk form. Turning copper into inks has however been the main challenge, primarily due to oxidation effects which are accelerated under warm and humid conditions. Oxidation turns copper into an insulator. At Printed Electronics Asia, copper materials will be explored by Miss Kyoko Kuroda from Hitachi Chemical.
While some use copper rather than silver to reduce cost, others are engaged in R&D for carbon nanotubes (CNT) and graphene as a viable alternative to Indium Tin Oxide (ITO), especially for transparent conductive films (TCF).
Dr. Sieglinde Pfaendler, University of Cambridge, will explain in great detail why they see metal oxide materials as a serious alternative to thin-film silicon and organics for large-area electronics. Also to be explained, a method of producing these materials using a scalable, plastic substrate compatible, high target utilization sputtering method, and a thin film transistor manufacture using these materials and the resulting device performance and stability.
Organic thin-film transistors (OTFT) are critical components for printed flexible electronics. Dr. Bang-lin Lee, Samsung Advanced Institute of Tech will present their recent developments of Thiophene and Thiazole based semiconducting copolymers and its applications for OTFTs.
Other conference topics include, Future of Transparent Conductors, OLED vs LED Lighting, Logic & Memory, Printed Electronics Manufacturing, Stretchable and Sensing Electronics as well as Solar Opportunities and Energy Storage.
