Poly(3-hexylthiophene) (P3HT) films were patterned by a soft lithography technique using a nanopatterned polydimethylsiloxane (PDMS) mold to generate one-dimensional (1D) grating and two-dimensional (2D) crossed line pillar patterns. The facilitated charge transport resulted in an improved response time and higher coloration and bleaching efficiencies for the P3HT-based electrochromic devices. In the patterned cell, diffraction modulation using an electrochromic operation was achieved. The switching efficiency (RDE) was 2 and 2.5 for the 1D and 2D patterned cells, respectively, indicating that EC control of the diffraction light intensity could be more effective in the 2D-patterned cell due to its improved EC properties. |
