The charge storage properties and applications of polymer brush electret — •Xinlei Ma — Research Center for Bioengineering and Sensing Technology, University of Science & Technology Beijing, Beijing 100083, People's Republic of China.

Electrets are dielectric materials that can store electrostatic charge over a long time scale. Although benefitting from the charge storage, such materials are widely used in electronics, machinery and biological systems. , challenges remain in principles explanation, facial processing and applications. The polyelectrolyte brush, which anchoring to a substrate with one end of the polymer chain and maintaining lots of fixed ions and counter ions on the surface will bring a further scope on the charge storage mechanism of polymer electrets. Of note, the polyelectrolyte brushes exhibit excellent environment robustness and well-organized chain conformation. Those properties endow superior control over surface structures and functionalities such as film morphology, grafting density, chemical composition, and many other surface properties, which will provide a feasible means to complicated structure fabrication and flexible sensor architecture.
