Microfluidic Production of Semipermeable Microcapsules by Polymerization-Induced Phase Separation

Hybrid porous material produced by polymerization-induced phase separation.

Herein we demonstrate a new, straightforward method for the synthesis of macroporous hybrid polymers coated with gold nanorods, which are strongly and uniformly attached to the surface of pores.

Self-Consistent Model of Polymerization-Induced Phase Separation

We propose an exactly solvable self-consistent kinetic model of polymerization-induced phase separation (PIPS) via spinodal decomposition. Using modified Cahn-Hilliard and Glotzer-Coniglio theories for early and late stages of spinodal decomposition, we find scaling regimes and compare the obtained results with existing experimental and theoretical information on PIPS kinetics, finding a qualit...

The morphology and dynamics of polymerization-induced phase separation

The morphology and dynamics of polymerization-induced phase separation in the initially homogeneous solution of a non-reactive component in reactive monomers are investigated by incorporating the reaction kinetics into the Cahn–Hilliard equation. Analytical results show that there is a reduction of the initial length scale in the early stage of phase separation. The reason is the increase of th...

Ion density deviations in semipermeable ionic microcapsules.

By implementing the nonlinear Poisson-Boltzmann theory in a cell model, we theoretically investigate the influence of polyelectrolye gel permeability on ion densities and pH deviations inside the cavities of ionic microcapsules. Our calculations show that variations in permeability of a charged capsule shell cause a redistribution of ion densities within the capsule, which ultimately affects th...
