PRINTABLE TECHNOLOGIES FOR HIGH SECURITY DOCUMENTS AND CONSUMER PRODUCTS

Grant number: LP160100071 | Funding period: 2017 - 2020

Abstract

This project aims to develop two next-generation printable security feature technologies to protect users from counterfeiting, which costs the world economy billions in lost revenue and undermines the security of citizens. First, it aims to enhance the security of banknotes by developing printable active device patches with energy harvesting flexible polymers as a power source and thin film graphene/polymer nanomaterial as an electrode/energy storage media. Second, it aims to design invisible carbon nanotube inks for optical authentication via near infrared activation. Both technologies are expected to thwart sophisticated counterfeits, particularly those supported by organised crime.
