Application of pH‐Responsive Viscoelastic Surfactant as Recyclable Fluid at High Temperature

A pH‐responsive amphiphilic surfactant stearic amide 3‐(N,N‐dimethylamino)propylamide (SAA) was synthesized and served as a thickener in aqueous solution to construct a switchable viscoelastic surfactant fluid (VES fluid). The structure of SAA was studied by 1H NMR, and the viscoelastic behavior of...
