Chemistry unit

The central topic is the development of synthetic approaches to nanosized molecular objects, possessing precisely designed shapes, sizes, and functionalities for their following use as monomeric units for manufacturing of advanced materials such as 2D-polymers and branched polymers. These polymers are promising materials for surface engineering, which is the most practical aspect of the present research. Unlike other methods of surface modification such as air plasma spraying, cold spraying, and electrodeposition (which produce films with thicknesses ranging from several microns to tens of nanometers) on metal surfaces, our approach allows making mechanically stable one-molecule thick covalent films which can be transferred on any surface. Perspective areas of application of these films include superhydrophobic surfaces, membrane technology, and microelectronics.
