E71-250-2 Run: phi0=0.89 T=0.75 N=250

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). 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)
Both PS and PO well-established by t~0.02. View phi and S profiles.
Transient network (polymer-rich) present at t~0.02. Network completely broken by t=0.04.

#1: "new" k1 -- from phi-based S(k): R ~ t0.15 (~ t1/6.7)
Domain growth slower than t1/3 immediately; no "intermediate" t1/3 behavior. Significant ordering from the start causes domain growth to slow down from the start.
