Research scientists at INM have combined the benefits of organic and inorganic electronic materials in a new type of hybrid inks. This allows electronic circuits to be applied to paper directly from a pen, for example. This requires printable electronic materials that can be printed and retain a high level of conductivity during usage in spite of their curved surfaces. Some tried and tested materials include organic, conductive polymers and nanoparticles made of conductive oxides (TCOs).
To create their hybrid inks, they coated nanoparticles made of metals with organic, conductive polymers and suspended them in mixtures of water and alcohol...
