a Stress-strain curves of PF, PFE, PFED5, PFED10, and PFED20. b Dielectric constants of VHB 4910 and PFED10 from 10 Hz to 106 Hz. c Comparison of dielectric constant (measured at 1 kHz) and Young’s modulus of VHB 4910 and PFED10. Error bars show s.d., n = 3. d Cyclic stress-strain curves of PFE, PFED10, and VHB 4910 subjected to strain at 300%. e Mechanical losses of VHB 4910 and PFED10 from −55 °C to 55 °C. f Storage modulus (G’) and loss modulus (G″) of VHB 4910 and PFED10 versus angular frequency from 0.1 to 400 rad s−1 at 25 °C. g SAXD patterns of PFE and PFED10. h Photographs of PFED10 sample being stretched to over 500% strain and recovering in 1 min.
