Professor Petar R. Dvornic received B.S. and M.S. degrees from the University of Belgrade, Department of Technology and Metallurgy. He continued his education at the Department of Polymer Science and Engineering, University of Massachusetts, Amherst, with M.S. (1978) and Ph.D. (1979) degrees. After several appointments in Yugoslavia and the U.S., Prof. Dvornic joined the Michigan Molecular Institute (MMI) in Midland, Michigan, in 1993 as a Senior Associate Scientist in the Nanochemistry and Molecular Architecture Group. At MMI he rose through the ranks to his current position as a Senior Research Scientist (1999-present). Prof. Dvornic's research interests are in the areas of: 1. Synthesis of new monomers and polymers . Step-growth polymerization reactions. Thermally stable polymers. Polysiloxanes and other silicon containing polymers. Aromatic polyamides, polyhydrazides, poly(amide-hydrazides) and related polymers. Rheologically rigid, semi-rigid and liquid-crystalline polymers. Liotropic liquid crystallinity. Flexible polymers and elastomers. Thermally stable elastomers. Liquid-crystalline elastomers. 2. Structure-property relationships in polymers. Thermal and rheological properties of polymers. Semipermeable polymer membranes. Permeability and permselectivity. Critical polymer molecular dimensions. Applications of polymers under extreme temperatures; as ultra high modules fibers; for reverse-osmosis and ultra filtration membranes; as elastomers, particularly high temperature elastomers; as liquid crystalline materials; in medicine, pharmacology and dentistry. 3. Unusual macromolecular architectures. Dendrimers, hyperbranched and other dendritic polymers: synthesis, characterization and applications. Rheological and thermal behavior of dendritic polymers. Dendritic polymer networks. Effects of macromolecular architecture on materials properties and structure-property relationships. Macromolecular isomerism. Nanoscopic chemistry. 4. Dendritic polymers-based nanotechnology. Silicon-containing dendritic polymers. Copolymeric dendrimers and hyperbranched polymers. Organic - inorganic nano-composites, molecular hybrids. Dendrimer-based nanocomposites. Applications of dendritic polymers nanotechnology in electronics, opto-electronics, nano-lithography, chemical and biological sensors, interlayer dielectrics, nano-domained networks and coatings, aquatic anti-fouling protection. |
