Tuning the Structural Color of Perovskite Nanosheet/Polymer Nanocomposite Hydrogels by Adsorption of Alkyltrimethylammonium
Mechanochromic structural‐color hydrogels are promising materials for sensing and display applications; however, simultaneous control of hue and brightness remains challenging. Here, we report a simple and effective strategy for tuning optical parameters by adsorbing alkyltrimethylammonium ions (CnTMA, where n denotes...
