Polymerization-induced phase separation

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...

Polymerization-induced phase separation in a liquid-crystal-polymer mixture.

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.

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...

Polymerization-induced viscoelastic phase separation in polyethersulfone-modified epoxy systems.

The polymerization-induced phase-separation process of polyethersulfone (PES)-modified epoxy systems was monitored in situ continuously on a single sample throughout the entire curing process by using optical microscopes, time-resolved light scattering (TRLS), scanning electronic microscopes (SEM), and a rheometry instrument. At specific PES content a viscoelastic transformation process of phas...
