Abstract

Using the methods of optical polarization microscopy, spectrophotometry and refractometry, we study the microstructure and optical properties of liquid crystal composites (LC composites) based on borosiloxane and LCD-1282 nematic liquid crystal that have been obtained for the first time. In the uniaxial stretching of composites, a new phenomenon in the formation of borosiloxane of microfilaments of liquid crystals in a matrix up to several centimeters in length is observed. The formation of microfilaments and their spontaneous destruction with the formation of microdroplets of liquid crystals are experimental and theoretically characterized.

Серия: Физика-Математика 2017 / No 2 35 of observed processes and an analytical expression relating the length and radius of the formed filament with the size of the droplets formed during its destruction are proposed and experimentally confirmed. Materials based on the investigated LC composites can be used in display technology and optoelectronics, for example, as microresonators and electron-optical sensors.
