Title
Physics and Materials Science of Colloid Spincoating
Abstract: Spincoating is a decades-old technology for making thin polymer films and is in turn a spin-off of the centuries-old technology of the potter's spinning wheel. It is one of a small handful of technologies for manufacturing-scale processing of polymer films. Make crystals with micrometer to nanometer lattice parameters using colloidal self-assembly is promising as a way to make photonic or magnetic materials. I will describe the unusual structure and dynamics of self-assembly when one drops a colloidal suspension on a spinning wheel. I will also describe preliminary applications of these colloidal thin films in the making of patterned magnetic materials.Brief Bio: Anand Yethiraj Associate Professor Memorial University St. John's Canada Postdoc: FOM Institute AMOLF Amsterdam Netherlands University of British Columbia Vancouver Canada PhD: simon Fraser University Burnaby Canada BSc: St. Xavier's College Mumbai.
