Abstract:
We present both lattice and off-lattice Monte Carlo simulations for multiblock copolymer chains of two lengths. N= 64 and N = 128, with microarchitectures (8-8)4 and (16-16)4, respectively. The simulations demonstrate that a variety of lattice and off-lattice Monte Carlo methods gives the same protein-like behavior, showing that the multiblock chains undergo a two-step transition, first from a swollen state to a secondary "pearl-necklace" state, and then to a tertiary superglobular state as the solvent quality decreases, that is upon cooling. © 2008 WILEY-VCH Verlag GmbH & Co.
