Co-polymers confined in small droplets may have a structure different from that in the bulk. These droplets are produced by annealing a spin-coated polymer film with a thickness... -
Organisation of Latex Particles in Solution and at the Water/Sapphire Interface
Polystyrene latex represents an excellent model system for studies of the physical properties of colloidal particles. The materials can be prepared with controlled size, and... -
Order in the bulk and at the surface of dispersions of colloidal particles
Highly ordered dispersions of charged polymer particles that are tens or hundreds of nanometres diameter can be prepared. These are useful model systems for self-assembly and... -
Large Scale Structure in CTAB/SDS-Polymer Solutions
This proposal continues our investigations into polyelectrolyte-surfactant solutions which form films at the air-solution interface. We have found that solutions of mixed... -
