Effect of nanofillers on surface charge mobility and alternative technique for electrostatic field measurement

This paper has the main purpose to assess the influence of nanofillers on the mobility of electrostatic surface charge buildup. Electro Hydro Dynamic actuators were produced and tested at a fixed voltage amplitude and frequency, using different thermoplastic dielectrics, some of which belonging to the family of nano-filled materials. The investigation focuses on the mobility of superficial electrostatic buildup, also experimenting the validity of an alternative high voltage potential measurement technique based on monitoring of multiple embedded electrodes. Results show that nanofillers have a profound effect on electrostatic charge buildup, strongly reducing their mobility.
