Researchers from the Australian Institute for Bioengineering and Nanotechnology at The University of Queensland have developed a tool for the controlled formation of various polymer particle topologies and morphologies, which take into consideration the complex interplay between various thermodynamic, kinetic and chemical factors. The technology involves manipulating the self-assembly of block copolymers in aqueous systems using fine chemical changes, such as pH and temperature. Topologies formed include spheres, rods, jellyfish, loops, multi-lobed spheres and hemispheres. The method allows for their rapid production at a concentration of 20 wt% in water. Potential applications include paints, adhesives, pharmaceuticals and cosmetics.
