The profile of surface potential in ON-2 electret across the sample along -axis as-fabricated (1), its decrease caused by the sequential anneal for 10 min at temperatures of 200, 350, 400, and 450°C, (2) to (5), respectively, followed by its anneal at a temperature of 450°C for 16 hrs (6), 40 hrs (7), and 110 hrs (8). The sample is 2 cm wide.
