Synthesis and Self -Assembly of Janus and Patchy Colloidal Particles

111 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2009.At the oil-water interface, Janus amphiphilic particles adsorb strongly. With simple calculations, I showed that the adsorption energy depends not only on surface tension but also on the Janus balance. I developed a rigorous mathematical definition of "Janus balance" that may find application in emulsions stabilized by Janus particles. On the experimental side, I performed experiments to quantify the efficacy of Janus particles to stabilize emulsions for extended times.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
