Recently, materials science researchers from Xi’an Jiaotong University, together with Southern University of Science and Technology and Pennsylvania State University, have designed a new electrochromic device with ionohydrogel with novel electrochromic layered structure. The research results have been published in the well-known journal “Materials Horizons” in the field of international materials. This research paper is entitled “Multidingal Hydrogel Enables Extremely Simplified Electrochromic Devices for Smart Windows and Ionic Writing Boards”. The research was supported by the National Natural Science Foundation,…
