Preferred Label : morphology coarsening;
IUPAC definition : Process by which phase domains increase in size during the aging of a multiphase material.;
Scope note : morphology coarsening can be substantially stopped by, for example, vitrification,
crosslinking, and pinning, the slowing down of molecular diffusion across domain interfaces.; representative mechanisms for coarsening at the late stage of phase separation are:(1)
material flow in domains driven by interfacial tension (observed in a co-continuous
morphology), (2) the growth of domain size by evaporation from smaller droplets and
condensation into larger droplets, and (3) coalescence (fusion) of more than two droplets.
the mechanisms are usually called (1) siggia s mechanism, (2) ostwald ripening (or
the lifshitz–slyozov mechanism), and (3) coalescence.; in the coarsening at the late stage of phase separation, volumes and compositions
of phase domains are conserved.;
