Title:  Soft Remotely Controlled Materials

Recent achievements in the synthesis and study of stimuli-responsive particulates preformed the development of the area of remotely controlled materials when electric and magnetic fields are used to trigger changes and responses in colloidal systems.  This seminar is to discuss our recent research projects on remotely controlled materials. Such materials promise plentiful applications, specifically at microscopic scale when a precise positioning of building blocks is substantially challenging due to thermal fluctuations. Homogeneous external fields provide energy sources that are sufficient to overcome thermal fluctuations and align building blocks in abroad range of dimensions from a few nanometers to micrometers. This area of field-directed assembly is receiving increasing attention owing to the possibilities for the generation of anisotropic structures at different length scales.

Not less diverse opportunities can be developed using non-uniform fields. In this case transport of particulates towards the greatest field gradient is used for generation of structures with complex architecture. Building blocks can be assembled into secondary structures which then are transported and assembled yielding hierarchically structured materials. Special attention is attracted by remotely controlled interfaces. Very intriguing opportunity to regulate remotely wetting/nonwetting, adhesive/non-adhesive, catalytic/inert transitions could stimulate a number of new applications and technologies.  


Sergiy Minko is the Georgia Power Professor of Fiber and Polymer Science at the University of 

Georgia. He received his D.Sc. in chemistry from the National Academy of Sciences of Ukraine in 1993. Between 1997 and 1998, Sergiy Minko was an Alexander von Humboldt Research Fellow at the University of Ulm, Germany and later he occupied a senior research position at the Leibniz Institute of Polymer Research in Dresden, Germany. Between 2003 and 2013, before joining the University of Georgia in 2014, he held Egon Matijevic Chaired Professor position at Clarkson University, NY.

His research is in the fields of stimuli-responsive materials, thin polymer films, polymer brushes, polymer gels, fibers and membranes, colloidal particles, and self-assembly. He has published over 180 journal articles, given over 150 professional talks, and filed 20 patents.
