Abstract

Analysis of the structure functions of intensity fluctuations of scattered laser light was applied to monitor the phase separation in probed disperse media. UV-cured mixtures of a liquid crystal and prepolymer were studied during the formation of the structure of dispersive polymer—liquid crystal (DPLC) composites. The experimentally observed features of light beating induced by dynamic light scattering in DPLC systems (the scaling properties of the structure functions, the narrowing of the beating spectrum for certain weight fractions of the liquid-crystalline component) were interpreted in terms of the discrete scattering model using the results of statistical modeling.

Values of intensity of detected signal (in arbitrary units) versus the time interval after the beginning of photo-polymerization; sample 1 –the weight fractions of LC807 and NOA65 are 40% and 60%, respectively; sample 2 –the weight fractions of LC807 and NOA65 are 50% and 50%; sample 3 –the weight fractions of LC807 and NOA65 are 60% and 40%, respectively. From the start of polymerization process, the stabilization stage begins for sample 1 after 60s, for sample 2 after 50s, and for sample 3 after 40s. Inset displays the forms of detected fluctuating signals at small time scales in the course of the stabilization stage.

Empirical normalized structure functions DI˜(τ)/2I˜2of the detected signals at the stabilization stage. The notations of curves are the same as in Fig. 2. The log-log plot clearly displays the power-law behavior of the empirical structure functions of intensity fluctuations at small time scales.
