AB  - Phase separation is a trivial phenomenon but a mature strategy in materials 
      science. The flexible materials are provided toughness and strength by phase 
      separation, yet there are few applications in optics and electronics industry. A 
      novel phase-separated dielectric gel (PSDG) with a strong Christiansen effect is 
      prepared via radical polymerization using hydroxyethyl methacrylate as a monomer, 
      4-cyano-4'-pentylbiphenyl and tributyl citrate as mixed solvents, and 
      polyethylene glycol as a softener. The solvent ratios and ambient conditions can 
      efficiently change the color of PSDG which makes it strongly selective for the 
      wavelength of transmitted light. Besides, it has a high dielectric constant (10 
      at 1 kHz), sensitively responding to the electric field. The phase separation 
      degree of PSDG varies with applied electric field, which will induce its 
      transmittance alteration accordingly. The current field sensitive PSDG provides a 
      novel idea for "smart windows". Additionally, varying the size and shape of the 
      electrodes can precisely control the phase separation in PSDG and also enables 
      the function of free writing on flexible materials. Therefore, the designed PSDG 
      has great application potential for flexible touch and interesting interactions.
