Biography

Dr. Voronov made his MSc thesis and doctoral degree at Lviv Polytechnical Institute, Ukraine His MSc thesis was focused on the synthesis of macroinitiators for radical polymerization and doctoral degree involved the study of the fabrication of grafted thin polymer films and their influence on composite properties. His first postdoctoral research stay at the Institute Charles Sadron in Strasbourg, France dealt with a behavior of polyelectrolytes adsorbed onto inorganic particles at a wide concentration range. It was demonstrated the intriguing oscillation phenomenon in the average aggregate sizes of covered particles with time of adsorption. From Strasbourg he moved to University of Ulm, Germany where investigated influence of interface structure on mechanical properties of polymer composites.

His following research in Bayreuth University, Germany, where he worked as an Alexander von Humboldt fellow (AvH Fellowship, 2000-2001, and Long-term cooperation AvH Fellowship, 2001-2003), focused on the investigations of thin triblock copolymer films “annealed” in the vapour of various solvents in order to induce microphase separation. For the research, he performed layer by layer treatment of film to study the underneath morphologies. Applying scanning force microscopy (SFM) and scanning electron microscopy (SEM), periodic structures (core-shell cylinders, perforated lamellae and gyroids) have been found with an increased polymer thickness.

Dr. Voronov primary research focus has been in polymer science, with 15 well-documented years of experience in synthesis, fabrication and characterization of thin polymer films and multicomponent polymer materials. In 2003 he moved to Institute of Particle Technology at the Friedrich-Alexander University Erlangen-Nuremberg where his research interests were much more interdisciplinary and cover polymer science, some technological aspects of nanoparticles fabrication, as well as colloid surface and interface chemistry.

He spent four years in Erlangen as a Staff Scientist. His research activities were mainly focused on nanoparticles’ synthesis, stabilization, controllable aggregation and structure formation. His research team has been able to synthesize a novel class of polymeric stabilizers that work both in polar and non-polar environments. It was possible to vary the hydrophilic-lipophilic properties of the particle coating with the attachment of “home-made” invertible oligomers. Amphiphilic properties of oligomers are the basis of new nanoscale structures, both in solution and on solid surfaces, which could be used in a broad range of applications.
