The Factors Determining Formation Dynamics and Structure of Ring-Shaped Deposits Resulting from Capillary Self-Assembly of Particles

The influence of different physicochemical parameters, such as particle concentration and size, droplet volume, dispersion medium composition, and substrate hydrophilicity, on the structure of deposits resulting from evaporating sessile droplets of colloidal dispersions has been studied.

Description
Summary:The influence of different physicochemical parameters, such as particle concentration and size, droplet volume, dispersion medium composition, and substrate hydrophilicity, on the structure of deposits resulting from evaporating sessile droplets of colloidal dispersions has been studied. Parameters enabling one to targetedly control the structure of a deposit have been determined. The possibility of obtaining deposits having the shapes of thin rings and monolithic disks has been shown. The conditions have been found under which monolayer and multilayer deposits with ordered arrangement of particles are formed.
