[Structural Transitions of Micellar Systems in Response to Diol Compounds Accompanied by Changes in Viscoelastic

Abstract:
External-stimuli-responsive smart viscoelastic systems have the potential for diverse applications. Worm-like micelles (WLMs) are distinct viscoelastic systems. Several stimuli-responsive WLMs have been reported thus far, in which modifications are triggered by pH variations, redox reactions, temperature shifts, and light. However, sugar-responsive WLMs have not been reported. Phenylboronic acid (PBA) reversibly forms cyclic ester with cis-diol compounds; therefore, it serves as a cis-diol sensor for compounds such as glucose (Glc) and fructose (Fru). Adding PBA to cetyltrimethylammonium bromide (CTAB) in a basic medium induces the transition of spherical micelles to WLMs. This is accompanied by a substantial increase in the viscosity of the CTAB/PBA system. Notably, the addition of Glc to the CTAB/PBA system induces the transformation of the WLMs into spherical micelles or short rod-like micelles. In this review, we describe diol-responsive micellar systems based on PBA and their rheological properties.

Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
