Abstract
Carbon nanotube (CNT)-doped polymer-stabilised blue phase (PSBP) liquid crystal cells driven by an in-plane field are fabricated. Their electro-optical properties are investigated for both single-wall and multiwall CNT dopants. A small amount of CNT dopants in PSBP liquid crystals leads to broadening the blue phase temperature range over 42°C and stabilising the reflection wavelength against temperature changes. A lower Kerr constant and threshold voltage are obtained for a higher CNT concentration. Higher CNT concentrations lead to an increase in the elastic constant; therefore, the rise time of CNT-doped PSBP liquid crystal cells increases and decay time decreases. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
