Morphology: At early times, system contains many small polymer-rich droplets. Many coalesce and form very long (but not thin and fibrillar) domains. At late times, these polymer-rich domains shorten but are still elongated.
Resulting intermediate/late-time structure: Elongated polymer-rich domains (minor phase) in a LC-rich matrix (major phase). View phi and S profiles.
Evolution of degree of PS and PO.
for PS (red): delta_phi(t) = phimax(t) - phimin(t)
for PO (blue): S(t) = Smax(t)
Plot indicates that both PS and PO are significant at t~6. phi and S profiles reveal that these times (at which this plot indicates a high degree of PS and PO) represent when PS and PO begin to be significant. (That is, there is at least one or two small regions that have strongly phase separated or ordered.)
For this quench, PS is fairly strong by t=6 and is well-established by t=8. PO becomes quite significant at t~8, not at t=6. At t=6, there there are only two small highly ordered LC-rich regions.
