Photoacid catalyzed organic-inorganic hybrid inks for the manufacturing of inkjet-printed photonic devices

Photoacid catalyzed jettable inks containing monomers with epoxy and silane functionalities have been successfully formulated. In contrast to inks based on conventional sol-gel processes, the hydrolysis and condensation processes in these materials are triggered after printing using UV light favorin...
