Ionic thermoelectric (ITE) materials have emerged as a new realm for energy harvesting from readily available heat sources. Transparent ITE polymer films were prepared via photopolymerization of ionic monomers and nematic liquid crystal monomers which provide ionic carrier sources and temperature responsive units, respectively, in an ITE film. In order to increase the softness of the polymer films and form ion channel inside, flexibility of the polymer network was controlled by adding polar photofunctional monomers of a high molecular weight. This film showed a reversible temperature programmability and p-type ITE property with a phase-controlled Seebeck coefficient of 2 mV/K at 80% RH.
