a Infrared differential spectrum of 2DPA under varying electric fields. b Bipolar polarization-electric field loops. c Maximum polarizations under electric fields of 60 and 120 MV·m−1. d–i Temperature-dependent dielectric permittivity and loss of the P3 polymer and 2DPA composites. The arrows indicate the polar phases induced by 2DPA.
