The phase behavior of a cross-linkable gemini surfactant that forms a type I bicontinuous cubic phase was investigated as a function of blending with commercial butyl rubber. The goal of this research was to develop novel, flexible nanoporous polymer composites with an interconnected pore architecture. Using polarized light microscopy and low angle x-ray diffraction, it was found that the Q phase of the polymerized Gemini surfactant can be formed and cross-linked with up to 10 wt% butyl rubber at various temperature. The water contact angle, mechanical properties and stability of the Q/butyl rubber components will be presented.
