University of Leeds. [Dataset] https://doi.org/10.5518/462

Dataset description

Contains opto-mechanical testing data for an all acrylate Liquid Crystal Elastomer observed to display a negative Poisson’s ratio coincident with a state of negative liquid crystal ordering. Also contains images from AFM and SEM studies of the material confirming the LCE has zero detectable porosity in strained and unstrained states. Dataset includes plotting files used to generate figures.
