WIPO Patent Application WO/2024/011760
Kind Code:
A1
Abstract:
Disclosed are a PLGlu-SS-lithium ion sieve composite material, a preparation method therefor, and a use thereof. The composite material comprises an H3LiMnTi4O12 lithium ion sieve and a gamma-polyglutamic acid compounded with the H3LiMnTi4O12 lithium ion sieve, the terminal amino of the gamma-polyglutamic acid being linked to a disulfide bond-containing group. According to the present invention, an H3LiMnTi4O12 lithium ion sieve is used as a supporting structure, providing sufficient strength support, structural stability, and good cyclic performance; the pore channels and surface of the lithium ion sieve are all bonded with PLGLU-SS, the PLGlu-SS is protonated and folded under a low pH value to form alpha-helix, and the PLGlu-SS is deprotonated and unfolded at a high pH value; therefore, by adjusting the pore size of the pore channels under alkaline adsorption and acidic desorption conditions, variable characteristics provide large adsorption capacity, high adsorption selectivity, and high adsorption efficiency, thereby providing an efficient lithium ion adsorption material having high adsorption capacity and high stability.
