However, they are also essential to formulate microemulsions which can serve as templates for nanostructured polymeric material. However, up to date the challenge is to copy the microemulsion structure to the desired structure of the polymer on a one-to-one scale. Recently Co et al. used a new class of highly viscous microemulsions that are composed of surfactant, polymerizable oil, and sugar to maintain the microstructure after polymerization F. Gao, C.-C. Ho, and C.C. Co, J. Am. Chem. Soc. 126, 12746 (2004). The addition of sugar enables the reorganization kinetics of the microstructure to be slowed down so that a changing monomer/polymer ratio during the polymerization does not lead to a phase separation. In this study, we started from the sugar-free microemulsion system H2O – n octane – n alkylpolyglycolether (CiEj) and increased the amount of sucrose/trehalose within the water phase up to 75 wt%. The shift of the phase boundaries to lower temperatures was compensated by replacing the CiEj surfactants with more hydrophilic sugar surfactants. Afterwards methacrylates were used instead of n-octane to formulate a highly viscous, polymerizable microemulsion, which can be polymerized via UV-irradiation. The obtained structures were investigated by dynamic light scattering (DLS), scanning electron microscopy (SEM) and small angle neutron scattering (SANS). It is shown for the first time that the size of the polymeric nanomaterial strongly correlates with the size of the underlying microemulsion. Systematic variations in composition and temperature provide polymer particles with radii between 10 to 100 nm. Furthermore for the first time, both lamellar and bicontinuous structures could be copied nearly one-to-one to the nanoporous polymer material.
