Polycarbazole and its copolymer are the well-known electrochromic materials, which show a dark green color at the applied potential. Reflective electrochromic display (R-ECD) based on polymeric microspheres containing carbazoyl pendants were prepared using the seeded swelling and polymerization method, then synthesized bicarbazole were refluxed with the chloro-functional groups. The porosity and content of carbazole groups were diversified by controling the amount of toluene and chloropropene in the 2nd monomer mixture, respectively. Response time of R-ECD was considerably affected by the specific surface area of microspheres, and the concentration of carbazole incorporated. The swelling procedure and morphology of polymeric microspheres were monitored utilizing an OM and SEM, respectively. Response time and color efficiency of R-ECD were measured by an electro-optic spectrometer. |
