Claim 0:
1. A carbon dioxide responsive self-thickening smart fluid based on supramolecular self-assembly, comprising a Gemini surfactant, a single-chain amide molecule with a tertiary amine head group, and water, wherein
the Gemini surfactant has a structure as follows:, , and
the single-chain amide molecule with a tertiary amine head group has a structure as follows:, wherein R is selected from an alkyl chain of C11-21; n is an integer selected from 1 to 3; p is an integer selected from 1 to 6; and Y is Cl or Br, and
the Gemini surfactant and single-chain amide molecule with a tertiary amine head group self-assemble to form a vesicle structure dispersed in water, wherein the hydrophilic head group is exposed outside and the hydrophobic tail is hided inside.
