Experimental investigations of DGEBA epoxy resin dispersed liquid crystal polymer systems for the development of new electronic devices

Abstract

The DGEBA: Diglycidyletherbisphenol A and Liquid Crystal (4′-Pentyl-4-Biphenylcarbonitrile (5CBLC)) have been used to fabricate the so-called DGEBA epoxy dispersed 5CB liquid crystals (DED5CBLC). The XRD study's findings suggest that 5CBLC fillers can be used to change the properties of DGEBA epoxy without significantly changing its structure. Results from optical measurements reveal that the amount of 5CBLC filler added to the new disc shape system can adjust the band gap. This provides a way to design disc shape systems with desired optical properties. A promising correlation exists between optical linear susceptibility, third nonlinear optical, and nonlinear refractive index with 5CBLC filler in the DGEBA epoxy matrix. This correlation is since all three of these properties are told to the electronic structure of the DGEBA epoxy matrix. AC-impedance and AC conductivity properties of DED5CBLC disc shape systems filled with various wt% CB molecules have been good for adding 5CBLC content and applied field frequency. The results show that the AC conductivity of the composite spreads with rising wt% 5CBLC filler content and frequency. The continuous Jonscher fitting theoretical curve can be used to characterize the relaxation process and predict the system's electrical properties at different frequencies. The shrink in impedance directs that the composite substance befalls more conductive.
