In this study, we examine the synthesis and characterization of polymer micelle using polymerizable cationic gemini surfactant (surfmer). In this work, polymerizable cationic gemini surfmer, (CH2)2 [BrN(CH3)2C11H22OCOC(CH3)CH2]2 (GSM) was newly synthesized and characterized. Also, a “monomer”-type surfmer of BrN(CH3)2C11H22OCOC(CH3)CH2 (MSM) was synthesized and characterized for comparison.<br>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 GSM can show the characteristic properties of gemini. Micelles of GSM and MSM were polymerized with 2,2-azobis(2-methylpropionamidine) as an initiator. The polymer micelles obtained were characterized with dynamic light scattering (DLS) measurements and TEM observations.<br>The particle-size distribution obtained from DLS measurements for polymer micelle indicates that the structure of polymer micelle synthesized from GSM 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. Hence, we can synthesize the nano-ordered organic particles having uniform particle diameter by using cationic gemini surfmer.
