Aqueous solutions of certain trisiloxane surfactants wet low energy surfaces (i. e., polypropylene, wax covered leaves). Investigations on the macroscopic spreading velocity, the phase behavior as well as first attempts to visualize slowly spreading drops of pure surfactants did not solve the questions about the structure of rapidly spreading surfactant solution drops and the evolution of the corresponding dynamic energy balance. Therefore, a strategy for the hydrophilic modification of fractal Ir electrodes surfaces for investigating these effects was developed.
