摘要
The pH-induced rheological property of octadecy trimethyl ammonium bromide with anthranilic acid was investigated. The viscoelasticity property and structural transformation of molecular self-assembly were comprehensively discussed by means of rheological measurements, dynamic light scattering and cryogenic-transmission electron microscopy. On the basis of surface tension results, the change of viscoelasticity was explained by calculating the packing parameter of P. UV–vis results confirmed that the pH-dependent interaction between the aromatic ring of anthranilic acid and the head group result in the transition between WLMs and spherical micelles, thus altering the viscoelasticity of WLMs.
