Solvent Selectivity Controls Micro- Versus Macrophase Separation in Multiblock Chains
Athanassios Z. Panagiotopoulos
Abstract:Monte Carlo simulations in the grand canonical ensemble
were used
to obtain critical parameters and conditions leading to microphase
separation for uncharged block copolymers with solvophilic and solvophobic
segments. Solvent selectivity was systematically varied to distinguish
between systems that undergo direct macrophase separation and ones
that initially microphase separate in the dilute phase. Finite-size
scaling was used to obtain the critical parameters. Interestingly,
corrections to scaling increase si… Show more
