Amphiphilic conetworks comprise hydrophilic and hydrophobic chains which microphase-separate when swollen with water. This way, a large amount of internal interfaces is created which is of interest for, among others, tissue engineering. Using end-functionalized star block copolymers for their synthesis results in model networks with low defect density.

We investigate amphiphilic conetworks from various acrylic blocks which differ in composition, water solubility and mechanical properties. Their degree of swelling in water depends strongly on these characteristics. We study the structures of these conetworks using small-angle X-ray scattering which reveals information about the microphase-separated morphology.
