Abstract
The thermal transitions of polyethylenimine (PEI) with an ionic dodecylbenzenesulfonic acid (DBSA) complexes were studied while still retaining the mesomorphic structure by simple blending. Results show that the thermal properties of polymer complexes can be modified while retaining the phases. Furthermore, a polymer may be dispersed nanoscopically into the lamellar structure of polymer(surf) complexes. the use of polymer complexes could be considered as an alternative for the nanoscopic dispersion of polymers.
