The slow relaxation time (τ 2 ) of sodium dodecyl sulfate (SDS) micelles, measured by the pressure‐jump technique, was maximum at 200 mM concentration at 25°C, indicating that the most stable micelles are formed at this concentration. This is presumably related to the optimum molecular packing in the micelle. The rate of solubilization of benzene and Orange OT dye into SDS solutions was also maximum at 200 mM concentration. The results are explained as follows: The distance between micelles ( i.

Abstract In this study, the composites of thermoresponsive poly( N ‐isopropylacrylamide) (PNIPAm) and mesoporous silica particles were synthesized. 3‐(Trimethoxysilyl)propyl methacrylate (MOP) was used to introduce double bonds on silica particles. First, MOP‐modified spherical silica particles were prepared by the sequential addition of tetraethyl orthosilicate (TEOS) and MOP into W/O (water‐in‐oil) emulsion. Second, PNIPAm‐grafted silica microparticles were synthesized by the radical copolymer
