Abstract
Lyotropic liquid crystalline systems (LLCs) offer exciting potential as templating agents, in that discrete nanometer sized domains can be generated using the ordered LLC morphologies as templates. This study focuses on the polymerization of polar and non-polar monomers in Pluronic[R] LLC systems and understanding how the varying degree of LLC order affects the polymerization mechanism as well as the resultant polymer morphology. Initial studies demonstrate that the order of the LLC mesophase has significant impact on the polymerization rate of polar monomers with accelerated polymerization rates being observed in more ordered LLC phases. For non-polar monomers, there appears to be an opposite trend with faster polymerization rates occurring in the less ordered LLC phases. This indicates that differences in monomer structure affect the monomer segregation behavior which has a significant effect on the polymerization rate and will have an ultimate effect on the resultant polymer morphology. In addition, when the textures of the LLCs are examined there is a general retention of the original LLC morphology both upon addition of monomer and after polymerization. This is important because to successfully template the LLC morphology the LLC structure must be retained during the course of polymerization. This study has allowed for further understanding of the factors relating to polymerizations in ordered systems and for further development of Pluronic[R] LLCs as templating agents
