Abstract

This dataset shows the agglomerate dimension and structure of oleic acid-coated superparamagnetic nanoparticles (SPIONs), which are dispersed in the nematic fluid of a thermotropic liquid crystal (LC), 4-cyano-4′-pentylbiphenyl (5CB). The analysed datasets were acquired from the raw images of the SPION-5CB mixtures obtained using cryogenic transmission electron microscopy (cryo-TEM) and polarised optical microscopy. The image data were quantitatively analysed to extract statistical information on the sizes of SPIONs and their agglomerates and the inter-particle spacing of the agglomerated SPIONs. This dataset supports the fundamental understanding on how colloidal nanospheres behave in an anisotropic fluid, and has a potential to be used as a part of database for automated design of new hybrid materials.
