Özet

A side-chain liquid crystalline polymer (SLCP) was investigated by measuring the laser-induced effects on molecular reorientation. A 20 mW He-Cd (lambda = 441.6 nm) laser was used as a pumping source during the measurements, which were performed by an impedance analyzer to see the effect of laser illumination on the polymer-doped and non-polymered samples. Dielectric anisotropy dependency is quantitatively estimated via capacitive measurements. Our results show that laser pumping causes a considerable decrease in the required amount of voltage for reorientation in the constructed SLCP composite. (c) 2005 Elsevier B.V. All rights reserved.
