Abstract Details

2019, Doctor of Philosophy, Ohio State University, Electrical and Computer Engineering.
Polypyrrole (PPy) as a versatile conducting polymer (CP) has been widely employed in flexible electronics, anti-static coatings, and soft ionic actuators. While prior studies have focused on the exploration of novel counterions (or dopants), this work aims to achieve demanding functions by systematic structural designs combined with precise fabrication techniques. Toward higher conductivity and electroactivity, I show that a network structure of conjugated chains maintains high macroscopic conductivity even at nanoscale thickness, an intrinsically preserved bilayer structure brings power-efficient single-side-passivation, and a laser-patterned configuration achieves diversely alterable deformation forms, such as squeezing, gripping, waving, lifting and rotation. I further demonstrate that the link from structure to function is deterministic and repeatable, and these geometrically enabled actuators are both electrochemically and mechanically robust. Such features have inspired the development of a wirelessly powered lightweight insulin pump for easily controllable microinjection. From materials to devices, this thesis highlights, although still a small portion of, the enormous potential of geometrically enabled CPs for advanced robotics and soft biomedical devices.
