Printing Techniques for Integration of Inorganic Nanomaterials on Flexible and Biodegradable Substrates

High-quality printed electronic layers are needed for resource efficient fabrication of high-performance electronics on flexible substrates. However, currently there is lack of suitable printing methods for the realisation of high-performance electronic layers. In this work, we present two new approaches to realise high-quality electronic layers by printing inorganic one-dimensional (1D) nanomaterials on diverse flexible and biodegradable substrates, namely: (a) direct transfer printing, and (b) in-tandem contact and transfer printing. The basic printing mechanism, advantages and device applications are presented for both printing methods. Both printing methods hold great potential for the development of next generation high-performance flexible electronics on large areas.
