Understanding the drying behavior of polymer-coated particle dispersions using optical tweezers

Project description

Optical tweezers pick up on the drying properties of particle–polymer–solvent mixtures

Many processes such as coating and ink-jet printing rely on particles dispersed in a solution and deposited onto a substrate. As the solution dries, undesirable effects can be produced much as dried coffee leaves a ringed stain. Scientists recently discovered that this ring-shaped deposit can be eliminated by coating the dispersed particles with surface-active polymers. With the support of the Marie Skłodowska-Curie Actions programme, the CoffeeRings project will investigate the mechanisms of the drying process with single-particle resolution using optical tweezers. The team will characterise the physiochemical properties of the polymer coating, its effect on the interactions of the particles and the drying behaviour of the particle dispersion.
