Richard J. Spontak was a research scientist with Procter & Gamble before he joined the NCSU faculty in 1992. Spontak has over 104 publications in peer-reviewed journals, and his work has been featured on the cover of Microsc. Res. Tech. and Langmuir. Spontak conducts studies to improve the current understanding of microstructural polymer systems, which are of scientific interest as self-assembling polymers and commercial value as adhesives, (bio)compatibilizing agents, nanotemplates, and membranes.
Annual Meeting Abstract
Multiscale Advances in Electroelastomers for Energy-Efficient and Controllable Shape Transformation
Author(s): Richard J Spontak
Dielectric elastomers (DEs) constitute an increasingly important category of electroactive polymers, a class of generally soft materials that, upon exposure to an electric stimulus, respond by changing size and/or shape. Derived from network-forming macromolecules, DEs are lightweight, robust and scalable, and they are furthermore capable of exhibiting giant electroactuation strains, high electromechanical efficiencies and relatively low strain-cycling hysteresis over a broad range of electric fields. Due primarily to their attractive electromechanical attributes, DEs are of growing interest in diverse biomedical, (micro)robotic, and analytical techno.. View More»
