We examined the synthesis and characterization of polymer micelle using polymerizable cationic gemini surfactant (surfmer). Here, cationic gemini surfmer (GS) was newly synthesized and characterized. Also, a "monomer"-type surfmer (MS) was synthesized and characterized for comparison. The equilibrium properties in water and in the presence of 0.1 M NaBr were investigated by means of surface tensions of the surfmer, indicating the GS can show the characteristic properties of gemini surfactant. Micelles of GS were polymerized and characterized with dynamic light scattering (DLS) measurements and TEM observation. The particle-size distribution for polymer micelle indicates that the structure of polymer micelle synthesized from GS is quite uniform. The average diameter of the particle is about 3 nm. The TEM image show that the nano-ordered organic particles were formed whose diameter is similar to that obtained by DLS measurement.
