PhD Topic – Self-Assembly in 3D Confinement forthesynthesisof Janus nanostructures
The self-assembly of block copolymers in spherical confinement has become a versatile route to generate microparticles with unusual and frustrated morphologies. To date, AB diblock copolymers have been the centre of investigation with studies on ABC triblock terpolymers being almost non-existent, despite their larger and more complex phase behaviour. The formation of an axially stacked lamella-ring (lr) morphology through confinement assembly of ABC triblock terpolymers in drying nanoemulsion droplets. This morphology consists of a concentric arrangement of B-rings sandwiched between axially stacked lamellae of A and C. Cross-linking of the B-rings locks the toroidal shape and Janus nanorings (JNRs) are obtained with two strictly separated brushes of A and C on top and bottom of the ring. The process can be extended to a variety of triblock terpolymers with different chemistry and block ratios to design multicompartment microparticles, patchy particles, and topological nanoparticles.
