Event Description
Dr. Ying Sun, assistant professor in Drexel's Department of Mechanical Engineering and Mechanics, will discuss how printable and flexible electronics, ranging from low-cost consumer products, solar cells, and low-power lighting to highly specialized small scale sensors and healthcare devices, have shown great potential to impact the energy, healthcare, entertainment, security, and military sectors. Roll-to-Roll fabrication using inkjet printing and direct laser patterning of flexible substrates is an enabling technology that will provide desired high-volume, low-cost production of flexible electronic devices. This talk summarizes Dr. Sun's and her team's combined modeling and experimental investigations on how the dynamics of specific transport processes impact the particle assembly and deposited micro/nanostructure of inkjet-printed colloidal drops. A fluorescence microscope and a high-speed side-view camera are synchronized to monitor in real-time capillary-driven particle self-assembly during the evaporation phase and to characterize the fluid transport and deposition morphology as a function of physicochemical properties of the colloidal suspension, substrate materials, surface modification methodology, surface roughness and temperature, and inkjetting parameters. Applications of inkjet printing to flexible electronics and thin film solar cells are also explored. |
