All-polymeric flexible transparent heaters (THs) are demonstrated for the first time. Thin films of four poly(3,4-ethylenedioxythiophene) (PEDOT)-based materials embedding different dopants exhibit low sheet resistances, down to 57 Omega sq(-1) associated with good transparencies (>87%) and a haze lower than 1%. These transparent thin films show excellent heating properties, with high heating rates (up to 1.6 degrees C s(-1)) and steady-state temperatures exceeding 100 degrees C when subjected to 12 V bias. Very high areal power densities were also measured, reaching almost 10 000 W m(-2). The temperature increase is finely fitted to, a thermal model. It is further demonstrated that these new THs can be efficiently integrated for applications in thermochromic displays and visor deicers.
