Effects of multiwalled carbon nanotube on holographic polymer dispersed liquid crystal

Abstract

The morphology and electro‐optical performance of holographic polymer dispersed liquid crystal (HPDLC) were investigated with the addition of multiwalled carbon nanotube (CNT), both pristine and chemically modified one (CNT‐CC). With the addition of CNT, the diffraction efficiency increased and showed a maximum at 0.6% while nucleation was delayed due to the increased mixture viscosity. Film was driven only with CNT due to the induced local electric field of polymer to overcome the threshold resistance. Among the two types of CNT, chemically modified one gave finer CNT dispersion, lower mixture viscosity, larger liquid crystal (LC) droplet, higher diffraction efficiency, and shorter response time while the pristine CNT decreased the driving voltage.

High‐performance holographic polymer‐dispersed liquid crystals by incorporating hyperbranched polymers

“…The electro‐optic performance of HPDLC films has been enhanced by doping with conducting fillers, such as fullerenes,13 carbon nanotubes (CNTs),14 and graphene 15. Zero‐ (fullerene) and one‐dimensional (CNT) additives increased the mixture viscosity and delayed the grating formation kinetics, regardless of their content.…”
