We present experimental data on time-dependent behaviour of the apparent pitch of a Cholesteric Liquid Crystal (CLC) when it is submitted to mechanical shearing deformations. In particular we are interested to study the molecular reorientation process after the application of the shear. A good agreement is found between the calculated value of the characteristic time of this process, from a simple model, and the experimental one.

Abstract
We present experimental data on time-dependent behaviour of the apparent pitch of a Cholesteric Liquid Crystal (CLC) when it is submitted to mechanical shearing deformations. In particular we are interested to study the molecular reorientation process after the application of the shear. A good agreement is found between the calculated value of the characteristic time of this process, from a simple model, and the experimental one.File in questo prodotto:
