Recently, hydrogels with adjustable mech. properties have been developed for information security applications. However, the defects such as easy drying and inferior resistance to extreme temperatures limit their extended applications. Herein, a fluorescent double-network ionogel doped with imidazole-modified carbon quantum dots (CQDs) is constructed by the dynamic covalent crosslinking of chitosan with glutaraldehyde and chem. crosslinking of acrylamide in 1-ethyl-3-methylimidazolium chloride (EMIMCl). The ionogel exhibits high thermal stability and good resistance to high and low temperatures In addition, the as-prepared ionogel possesses good viscoelasticity with high elastic modulus (G’, ~105 Pa) and a viscosity of ~104 Pa.s. Attributed to the excellent stretchability, durability and self-adhesion in a wide operating temperature range, the ionogel has been successfully constructed to a mechanochromic fluorescent device for the reversible encryption and decryption of the information. Dual stimuli of UV light and force are required to reveal the hidden information. Besides, the dynamic Schiff base bonds formed by amine groups of chitosan and aldehyde groups of glutaraldehyde allow the ionogel to quickly repair damages without external stimulation, prolonging its service life. Therefore, this work reports a new strategy for the preparation of soft materials for more secure information encryption by using high-performance ionogels. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a solvent as well as catalyst for the depolymerization of oak wood lignin; a solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brønsted acid catalysts.Recommanded Product: 65039-09-0
