ABSTRACTWe performed Brownian Dynamics simulations of multiblock copolymers of A and B polymers in a solvent selective for the A block at a volume fraction of 20%. Tri-, penta- and heptabocks were simulated. Fourier transformation reveals micellar clusters arranged in a BCC lattice, in agreement with scattering experiments. The clusters were analyzed using a percolation approach and we observed larger clusters when the outermost block was in the poor solvent condition. The ratio of number of loops to bridges decreases as the number of blocks in the copolymer increases, as does the polydispersity. Increased penalty of looping as the number of blocks increases leads to a larger number of smaller clusters with more bridges.

This paper presents a theoretical and experimental investigation on the irreversible deposition of colloidal particles from electrokinetic microfluidic flow in parallel plate channels. The electrokinetic particle transport model presented in this study is based on the stochastic Langevin equation, incorporating the electrical, hydrodynamic, DLVO colloidal interactions and random Brownian motion of colloidal particles. The particle trajectories are computed via the Brownian dynamics simulation technique and the particle deposition is quantified in terms of the surface coverage. Direct videomicroscopic observation using the parallel-plate flow cell technique, is employed to determine the deposition kinetics of polystyrene latex particles in NaCl electrolytes. The theoretical predictions are compared with experimental results, and a reasonable agreement is found.
