A new concept of a high-capacitance flexible polymeric dielectric based on P(VDF-TrFE):P(VDF-HFP)-[EMIM] [TFSI] blends is reported by Yong-Young Noh and co-workers in article number 1605685. This solid-state electrolyte gate insulator enables remarkable field-effect mobilities exceeding 10 cm² V⁻¹ s⁻¹ at V_g ≤ 2 V for common conjugated polymer, amorphous metal oxide, and carbon nanotube semiconductors. Such an impressive performance is achieved by a high areal capacitance of >4 μF cm⁻² owing to the combined polarization of CF interface dipoles and electrical-double-layer formation.
