Abstract
Oscillating dynamics of cis-trans isomerisation of the azobenzene can boost free volume generation in liquid crystal polymer networks. As such excess volume can influence the guest molecules’ motion by influencing the space around them, the isomerisation process could be used for applications involving molecular transport. The paper by Cao et al., reports the investigation of a photomechanical effect in a polymer network for molecular transport purposes. The transport of 5CB liquid crystal through a chiral nematic polymer network consisting of azobenzene units is investigated. ~28% increase in diffusion is observed from light OFF to light ON state. The influence of polarisation of the incident light on the diffusion process is studied.
