IPEC Solver: Numerical simulation tool to study inter-polyelectrolyte complexation

Comp. Phys. Comm., 184 (9), 2221–2229 (2013)
B. Huang and V.A. Baulin

IPEC Solver is a Windows program designed to analyze the stability of core–shell inter-polyelectrolyte complexes formed by complexation of oppositely charged block copolymers. The two-dimensional size distribution of the complexes composed by different numbers of positively or negatively charged polyelectrolytes is calculated based on the […]
