Nano-Sized Polymer Micelle Synthesized from Cationic Gemini Surfmer
نویسندگان
چکیده
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.

Molecular connectivity indices for modeling the critical micelle concentration of cationic (chloride) Gemini surfactants
The molecular connectivity indices were used to derive the simple model relating the critical micelle concentration of cationic (chloride) gemini surfactants to their structure. One index was selected as the best to describe the effect of the structure of investigated compounds on critical micelle concentration consistent with the experimental results. This index encodes the information about m...
