Chemistry Special Seminar - Benoit Lessard, University of Ottawa
Benoit Lessard, Canada Research Chair in Advanced Polymer Materials and Organic Electronics, University of Ottawa will present a special seminar on March 25 at 10:00 am in Arts 214.
Title
“Green” Electronics: from sustainable materials to cannabinoid sensors
Abstract
Our society is faced with an increasing challenge of E-waste and with the proliferation of the internet of things and smart packaging this is only going to get worse. Low cost printed electronics, are facilitating the development of emerging technologies from artificial skin to stretchable and bendable cell phone displays. The desire to integrate these materials onto biodegradable substrates or to use compostable active materials is necessary. Furthermore, the chemical toolbox available to us enables the fine-tuning of the materials to design and engineer the desired properties. This seminar will cover our groups recent advances in 1) the simple fabrication of semiconductive single walled carbon nanotube transistors on high performing green dielectrics;[1,2], 2) advances towards the development of biodegradable and flexible transparent heaters [3,4] and 3) the use phthalocyanines as low cost semiconductors for the development of point-of-source sensors such as cannabinoid detection and speciation [5,6]. We aim to build structure property relationships between material design, thin film processing and device performance for the enabling of sustainable next-generation electronics.
