Abstract

Physical Sciences Physics Physics, Applied Science & Technology
We show that graphene-percolated polymer composites exhibit fractional capacitance response in the frequency range of 50 kHz-2 MHz. In addition, it is shown that by varying the loading of graphene within the matrix from 2.5% to 12%, the phase can be controllably tuned from -67 degrees to -31 degrees, respectively. The electrostatic fractional capacitors proposed herein are easy to fabricate and offer integration capability on electronic printed circuit boards. (C) 2013 AIP Publishing LLC.
