The effect of solvent size on physical gelation in triblock copolymer solutions

摘要: The gelation of physically associating triblock copolymers in a good solvent was investigated by Monte Carlo simulation, and the effect size on discussed detail. can greatly affect conformation distribution polymer chains, micelle, mechanism microscale, mesoscale, macroscale. Our results indicate that physical exhibits three distinct regions. closely couples to chain transition when is normal or quasinormal; occurs simultaneously with phase separation approaches ideal end-to-end distance chains; follows glass upon increasing much larger than chains. We also found volume fraction gel point shift from 0.20 0.06, range broader reported literature.
