제목 Patterned Electrochromic Conjugated Polymers for Reversible Full Color Generation
초록 The electroactive conjugated polymers (CPs) based on polythiophene were micro- or nano-patterned by the micromolding in capillaries (MIMIC) process to fabricate line gratings. Under irradiation by white LED light source, transmissive or reflective colors are generated by the diffracted light in a single device and can be changed by the applied potential due to refractive index change determined by doping level of conductive polymers. The diffracted colors including red, green, and blue was blue shifted by increasing the doping level or changing the angle of incidence. This patterned CPs showed a memory effect longer than 40 hours, keeping their color and intensity of over 85%.
