Abstract

The invention discloses a disulfide bond-containing CO2/N2 and redox stimuli-responsive worm micelle system and a preparation method thereof. The preparation method comprises the steps that an anionic surfactant is added into cystamine bicarbonate mother liquor, stirring is conducted till the anionic surfactant is completely dissolved, and then the worm micelle system is obtained, wherein the anionic surfactant is one or more selected fromsulfate, sulfonate, carboxylate and phosphate ester salt with C6-C18 linear/branched chains and saturated/unsaturated single-long-chain or double-long-chain alkyl with or without aromatic nucleus. The CO2/N2 and redox stimuli-responsive worm micelle system containing the disulfide bond, disclosed by the invention, has the stimuli-responsiveness to CO2/N2 and redox; the raw materials are simple in composition and low in price, and tedious steps of organic synthesis, separation and purification and the like are not needed; and the formed worm micelles are high in viscosity and have great application prospects in the fields of fracturing fluid, material preparation, drug release and the like.

Description

technical field [0001] The present invention relates to a CO containing disulfide bond 2 / N 2 The invention relates to a redox stimulus-responsive worm micellar system and a preparation method thereof, which belong to the technical field of colloid and interface chemistry. Background technique [0002] Wormlike micelles are one of the association structures of amphiphilic molecules in aqueous solution. When the surfactant increases the concentration of the solution or adds a counter-ion salt, it self-assembles in the solution to form micelles with a flexible network structure, which exhibits remarkable viscoelastic properties similar to flexible polymers, and is a kind of " Models of "equilibrium polymers" (or "living" polymers) that can elongate linear structures by repeated destruction and generation. In the past two decades, worm-like micelles have attracted great interest, from theoretical research to industrial technology applications, and the research scope has been...
