Disulfide bond-containing multi-stimuli-responsive worm micelle system and preparation method thereof

Abstract

The invention discloses a disulfide bond-containing multi-stimuli-responsive worm micelle system and a preparation method thereof. The preparation method comprises the following steps: adding a cationic surfactant into a 2,2'-dithiodibenzoate mother solution and stirring until the cationic surfactant is completely dissolved to obtain the worm micelle system; wherein the cationic surfactant is one or more of C6-C18 straight-chain or branched-chain, saturated or unsaturated, single-long-chain or double-long-chain quaternary ammonium salt, which contains or does not contain aromatic rings, pyridinium salt, imidazoline salt, morpholine salt, guanidine salt and triazine salt. The provided disulfide bond-containing multi-stimuli-responsive worm micelle system has multi-stimuli responsiveness to pH, temperature and oxidation reduction; the raw materials are simple in composition and low in price, and complex steps of organic synthesis, separation and purification and the like are not needed; the formed worm micelle is high in viscosity and has a great application prospect in the fields of material preparation, drug release and the like.

Description

technical field [0001] The invention relates to the technical field of colloid and interface chemistry, in particular to a multiple stimulus-responsive worm micelle system containing disulfide bonds and a preparation method thereof. Background technique [0002] Self-assembly behavior (Self-assembly) refers to the comprehensive action of various non-covalent bonding forces such as hydrogen bonds, electrostatic forces, van der Waals forces, hydrophobic forces, and π-π stacking forces between molecules. The process of forming ordered aggregates. However, not all molecules can spontaneously self-assemble, and two necessary conditions must be met. The first is the driving force of self-assembly and the guidance of self-assembly, and the interaction between countless non-covalent bonds Coordination is the key to the stable and complete maintenance of a certain shape and structure of the self-assembled system; the second is that the structure and size of the molecules must meet t...

Problems solved by technology

[0005] At present, there have been many reports on the research of environment-responsive worm micelles, mainly in the synthesis of surfactants or polymers with special structures, but there are few research reports on the use of cheap organic compounds to construct environment-responsive worm micelles.
