Dynamic Viscoelasticity and Concentration Dependence of Micelle-Gel Transition of S_mntBAM_n Diblock Copolymer Solutions

摘要

Self-assembled block copolymer (BCP) solutions, including micelles and gels, have gained considerable importance due to their numerous applications such as responsive materials, adhesives, drug delivery vehicles. The transition of micellar solution to gel phases is through gel point at which critical gels are formed. These critical gels exhibits characteristics of both, viscous liquid & hookean solid and relax at infinite time, in a broad distribution of shorter modes which are self-similar. Investigations on the existence of critical states are of high significance with regards to industrial interests and fundamental research.
