dc.description.abstractIn this study, the effect of methyl red (MR) concentration variation on conductivity and optical bandgap parameters of 4-pentyl-4'-cyanobiphenyl (5CB) nematic liquid crystal and norland optical adhesive 65 (NOA65) photopolymer (5CB:NOA65) composite was investigated. As a result of the experimental studies, wavelength-dependent absorbance, frequency-dependent dielectric constants (epsilon' and epsilon''), and alternating current (ac) conductivity (sigma(ac)) graphs of the samples were obtained. Also, dielectric anisotropy (Delta epsilon'), direct current (dc) conductivity (sigma(dc)), and optical bandgap (E-g) parameters were determined. It was observed that epsilon', epsilon'', and rac increased with increasing MR concentration at low frequency region. On the other hand, it was concluded that Delta epsilon' and E-g decreased with increasing MR concentration. It has been seen that the results are compatible with each other and it is thought that composites may be useful for liquid crystal-based devices.en_US
