Polymer networks topography

The calculations were performed for e = 29.8 and = 6.1, assuming as in Ref. [3] the same dielectric anisotropy for the polymer network. The Cy versus y characteristics for three samples (A, B, and C) with R/a = 3 and same polymer concentration ( 9%), but different network topography, is shown in Fig. 10. In Prtedericksz-like geometry where the external field is strictly perpendicular to fibers (samples A and B), the orientational transition happens abruptly at a well-defined threshold (r/ and t]b, respectively, with r/ > r/s). In sample C network irregularities further decrease the switching threshold (r/cl not well-defined anymore), yet keep the reorientational process relatively sudden. The thresholds for...
