The effect of fullerenes on the dynamic characteristics of liquid crystal systems

Time and modulation characteristics of the electrically controlled liquid c rystal cells (conventional nematic or containing a polymer-dispersed layer) with fullerene-modified orienting coatings are studied as being dependent on the amplitude and repetition rate of applied electric pulses. A substant ial decrease in the switching time of the liquid crystal systems with fulle rene-containing orienting layers is demonstrated. The effect of data storag e controlled by variable electric pulse duration is observed in fullerene-c ontaining polymer-dispersed liquid crystal systems. (C) 2000 MAIK "Nauka / Interperiodica".
