摘要: We study the self-assembly of amphiphile molecules in water as a function temperature and concentration Monte Carlo simulations on two-dimensional lattice, which each molecule occupies single site, three sites. determine free aggregate-size distribution P(n) functions total surfactant for different temperatures. The degree micellar organization is characterized by Δ≡P(nmax)−P(nmin), where nmin nmax>nmin are aggregate sizes at P exhibits its local minimum maximum. show that Δ vanishes continuously we increase temperature, find exponent associated with this to nonmicellar transition.
