(Simulation Utilities for Soft and Hard Interfaces )

SUSHI calculates the equilibrium and non-equilibrium structures in polymer blends and block copolymers by solving the Self Consistent Field theory, GRPA(General Random Phase Approximation) and Hybrid method.
SUSHI can deal with a variety of polymers; linear polymer, branched polymers with any topology, copolymers with any monomer sequences (block, random, tapered-random) and the polymers grafted on a solid surface. SUSHI can be used to study the surface modification caused by polymer grafting or polymer adsorption, and the self-assembly of block polymers (micellar formation). Hydrodynamic effects can be treated. Parallel simulation based on GPGPU and MPI is possible.

Examples of applications

Self-organized sttucture of block copolymer :
Block copolymers form various nanostructures by micro-phase separation. The figure shows the hexagonal cylindrical structure of ABC star block copolymer (left) and the lamellar structure of ABC tri-block copolymer (right).
Micellar formation of block copolymer :
The critical micellar concentration of block copolymers in a selective solvent can be determined by SUSHI.
Reaction induced phase separation :
Simultaneous polymerization and graft copolymerization in polybutadiene and polystyrene system creates a salami-like structure. This phenomena, observed in high-impact polystyrene, is reproduced by SUSHI.
