Dynamic Surface Tension Behaviour in a Photoresponsive Surfactant System
We report on the surface properties of a photoresponsive surfactant that incorporates the light-sensitive azobenzene group into its tail. Cis-trans photo-isomerization of this group alters the ability of the surfactant to ...
Photo- and Thermoinduced Sol-Gel Transitions in Blends of Azobenzene Copolymers and Pluronic Surfactants
Novel self-assembling copolymers of 4-Methacryloyloxyazobenzene and NN-dimethylacrylamide (MOAB-DMA) exhibiting a pronounced photoviscosity effects in water are described. An optimum polymer architecture corresponding to ...
