Spin-coated highly aligned silver nanowire networks in conductive latex-based thin layer films

Continuum percolation in colloidal dispersions of hard nanorods in external axial and planar fields

“…81 From an application point of view, the situation is even more complex due to the impact of the manufacturing process, including spin coating and shear mixing, on the orientational order in the particle dispersions. 29,82 Even in controlled laboratory experiments, external electric, magnetic or flow fields are difficult to avoid, and our results show that the effects of such weak external fields on the percolation threshold can be significant. We believe that this can in part explain the huge scatter in the experimental measurements of the conductivity of nanocomposite materials that seem superficially very similar.…”

Orientation and stretching of supracolloidal chains of diblock copolymer micelles by spin-coating process

“…It is considered that during the spin-coating process, the outward flow generated by centrifugal force causes supracolloidal chains to align radially. 29,39,40…”

“…It is considered that during the spin-coating process, the outward flow generated by centrifugal force causes supracolloidal chains to align radially. 29,39,40 We note that variations in the coating conditions, such as colloidal concentration, spinning speed, and surface hydrophilicity of the substrate, scarcely affect the orientation of supracolloidal chains. For example, 0.02 wt% and 0.03 wt% solutions of supracolloidal chains resulted in similar values of the 2D order parameter S, with values of 0.41 and 0.37, respectively, although the chains on the substrate appeared slightly denser with a higher concentration (Fig.…”
