Postdoc with Junior Fellow Svetlana Santer
Dr. A. V. Vivek studied organic chemistry at the Indian Institute of Technology Madras and received his Master of Science degree in chemistry in 2002. He received his PhD, working on the graft copolymers via ambient temperature ATRP- synthesis and characterization of new materials at Department of Chemistry, Indian Institute of Technology Madras in 2008 under the supervision of Prof. R. Dhamodharan. He has been worked on many projects in synthesis and characterization of new graft copolymers and its application like stimuli, conducting polymer, template for nanomaterials, lithography and self assembled microporous materials. In 2008, he became a postdoctoral fellow in the School for Soft Matter Research at FRIAS in AFM group PD. Dr. Svetlana Santer. His current research focuses on controlled polymerization onto the nano-particulates and planar substrates.
The importance of this project is to study the domain memory effect of diblock-copolymer brushes comprehensively. The block copolymer brushes are responsive of switching their morphology in response to various external stimuli, such as changes in electrical potential, temperature, and pH or the presence of a specific chemical substance via different phase-segregation mechanisms. The physical and chemical properties of the brush layer may be precisely tuned through the monomer chemistry, polymer architecture, grafting density and molecular weight distribution, which in turn may be controlled with through polymerization chemistry. The important aspect of this project is that the nanoparticles could be used as carriers for polymer brushes.
