摘要
Amphiphilic diblock copolymers proved to dramatically increase the efficiency of surfactants in bicontinuous microemulsions. Now we investigated corresponding homopolymers as possible additives for microemulsions in order to tune the viscosity. Experiments showed that the efficiency is decreased, which qualitatively agrees with a theory of Eisenriegler. Simultaneous addition of diblock copolymers and homopolymers showed the possible superposition of the two opposite effects, and allowed to keep the efficiency constant with increased polymer content.
