Pattern formation in desiccated sessile colloidal droplets with salt admixture: Short review

摘要: This short review is devoted to the simple process of drying a multi-component droplet consisting complex fluid containing salt. These processes provide fascinating subject for study. The explanation rich variety patterns formed not only an academic challenge, but problem practical importance, as applications are growing in medical diagnosis and improvement coating/printing technology. fundamental scientific study mechanism micro- nanoparticle self-organization open systems. specific be solved, related this system - investigation mass transfer processes, formation evolution phase fronts identification mechanisms pattern formation. drops liquid dissolved substances suspended particles assumed on horizontal solid substrate. chemical composition macroscopic properties fluid, concentration nature salt, surface energy substrate interaction between which determines wetting, all affect final morphology dried film.
