SILICON-CONTAINING STRUCTURES AT INTERFACES - THE WETTING BEHAVIOR OFCARBOHYDRATE MODIFIED SI SURFACTANTS ON PERFLUORINATED SURFACES AND THE MODIFICATION OF ROUGH METAL-SURFACES BY HYDROPHILIC POLYSILOXANE NETWORKS

Aqueous solutions of certain trisiloxane surfactants wet low energy su rfaces (i. e., polypropylene, wax covered leaves). Investigations on t he 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 surfa ctant solution drops and the evolution of the corresponding dynamic en ergy balance. Therefore, a strategy for the hydrophilic modification o f fractal Ir electrodes surfaces for investigating these effects was d eveloped.
