Liquid crystalline networks have attracted more and more interest in recent years because of the potential application in artificial muscles, soft robotics, microfluidics, 4D printing, etc. Since their chemical structures contain the cross-linked networks and mesogens endowing them with good processability, stability and mechanical performance of polymers along with the adjustable orientation of liquid crystal molecules, the liquid crystalline networks usually have the advantages such as editable appearance, tunable function, and responsiveness to diverse stimuli. Thus, shape and color information can be accurately written into the material, which will reappear under specific external stimulus (e.g., light, heat, electric field, and solvent), thus can realize the storage, encryption and reading of information. This review briefly discusses the information storage mechanism based on liquid crystalline networks with manipulatable color (e.g., structural color and fluorescence) and shape memory. Their applications in camouflage, multi-level information storage and information transmission are also summarized.
