Research interests

Polymer Chemistry

Current research

  • Synthesis of macromolecular architectures by controlled radical polymerization (RAFT) in homogeneous (solution, bulk) and heterogeneous conditions (dispersion or emulsion polymerization)
  • Assembly of amphiphilic copolymers, main focus: PISA = polymerization induced self-assembly
  • Core-shell latexes for nanostructured films
  • Functional nanogels
  • Polyoxometalates-polymer hybrids

Selected recent results

1) Synthesis of core-shell particles of various morphology by PISA through RAFT dispersion or emulsion polymerization (ref. 1)

2) Hydrogen-bonded, nanostructured films from core-shell latexes (ref. 2)

3) Synthesis and characterization of thermoresponsive core-shell nanogels by RAFT dispersion polymerization
