Bulk PNIPAm temperature-dependent spectroscopy. Real and imaginary conductivity (a, top left), dielectric constant (b, bottom left) at 27 °C (black), 33 °C (red), and 37 °C (green) for bulk PNIPAm formed using free radical polymerization. c (top right) The temperature (T)–dependent conductivity σ ′ (f, T) shows a strong decrease around the phase transition temperature of ~ 32 °C. d (bottom right) d (log σ ′ )/d log (f) at 27 °C (black), 33 °C (red), and 37 °C (green) showing the extent of MWS polarization in the sample
