An electric field-sensitive polyacrylamide/MXene hydrogel and a preparation method and application thereof relate to the field of adsorbing organic dye hydrogel and preparation thereof. Acrylamide, ammonium persulfate, N,N'-methylenebisacrylamide, tetramethylethylenediamine and deionized water were added to the MXene dispersion, dissolved by magnetic stirring, and subjected to a cross-linking reaction to obtain a three-dimensional network. Structured polyacrylamide/MXene hydrogels, with MXene accounting for 0.1‑0.9% of the total mass of acrylamide and MXene. The prepared polyacrylamide/MXene hydrogel has excellent mechanical properties, swelling properties and electrical conductivity, and has the advantages of high selectivity, adsorption efficiency and removal rate, and good recycling capacity for cationic organic dyes. It has broad application prospects in processing. |
