N=150 vs. N=250: phi0=0.89 T=0.75 (E7)

Initially unstable with respect to PS and PO, but more unstable with respect to PO.



Morphology: Interconnected polymer-rich network (minor phase) containing LC-rich droplets (major phase). LC-rich droplets continue to grow, causing the surrounding polymer-rich regions to become thin and fibrillar. The LC-rich droplets eventually break up this polymer-rich network, resulting in polymer-rich droplets in a LC-rich matrix.

Resulting intermediate/late-time structure: Noncircular polymer-rich domains (minor phase) in a LC-rich matrix (major phase).

#1: "new" k1 -- from phi-based S(k).
Domain growth appears to follow a power law behavior, particularly with a power law inbetween 1/5 and 1/6.
Domain growth is immediately significantly slower than that in Model B (t1/3), regardless of system size.

#2: "new" k1 -- from phi-based S(k).
Domain growth appears to be slightly slower for the larger system size. N=250 data, however, are only from one initial configuration, whereas N=150 data have been averaged over 7-10 different initial configurations. Furthermore, N=250 data fall within the N=150 error bars.
