All data points have been averaged 8-10 different initial configurations. Error bars are included in the plots below.
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 average of PS and PO. Error bars included.
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 ~ t0.18 (~ t1/5.6)
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.
Although our calculated power law produces a good fit to our data, this system does not exhibit true scaling behavior, except maybe towards the end of this time frame.
#2: phi-based S(k) vs. S-based S(k): using "new" k1.
phi-based data: R ~ t0.18
S-based data: R ~ t0.14
Late-time results similar for phi- and S- based data. Difference in earlier-time data results in slower growth rate for S-based data (when compared with phi-based data).
#3: phi-based S(k) vs. S-based S(k): using "old" k1.
phi-based data: R ~ t0.24
S-based data: R ~ t0.22
S-based data give a slightly slower growth rate than phi-based data.
We can compare these results to those of a different lattice size:
