This paper provides insight into the kinetics of degrafting poly(methyl methacrylate) (PMMA) brushes using tetrabutylammonium fluoride (TBAF) and demonstrates how the process can be modeled using a series of degrafting reactions. The trichlorosilane-based polymerization initiator utilized here to synthesize PMMA grafts by surface-initiated atom transfer radical polymerization anchors to the silica substrate by up to three potential attachment points. During the degrafting sequence this anchoring reduces to two and one chemical bond and finally results in complete liberation of the PMMA macromolecule from the substrate. We investigate the effect of TBAF concentration, the initial grafting density of PMMA grafts on the substrate, and TBAF exposure time on degrafting of PMMA by monitoring the instantaneous areal grafting density of PMMA on the sub...}, number={24}, journal={MACROMOLECULES}, author={Patil, Rohan and Miles, Jason and Ko, Yeongun and Datta, Preeta and Rao, Balaji M. and Kiserow, Douglas and Genzer, Jan}, year={2018}, month={Dec}, pages={10237–10245} }

 @article{datta_genzer_2013, title={Computer Simulation of Template Polymerization Using a Controlled Reaction Scheme}, volume={46}, ISSN={["1520-5835"]}, DOI={10.1021/ma3025915}, abstractNote={We employ a Monte Carlo simulation scheme based on the bond fluctuation model to simulate template polymerization via controlled polymerization scheme involving copolymerization of free monomers (A) and monomers bound to a template (B) that consists of linear or ring-like substrates with equidistant sites occupied by bound B monomers. Both A and B are chemically identical; i.e., there is no interaction potential acting between A and B. A new macromolecule is initiated in bulk by activation of an initiator; any monomer that is within the reaction distance (nearest neighbors) of the initiator can be incorporated into the chain. As the macromolecule grows, it adds either bulk (i.e., A) or template-bound monomers (i.e., B) to its chain. The living nature of the polymers is assured by eliminating any termination or chain transfer. We analyze the effect of the number and spacing of the B bound monomers on the substrate on the chemical composition and monomer distribution in the resultant A–B random copolymer. Our results reveal that the likelihood of B being incorporated in the A–B copolymer increases with increasing the number and density of the B monomers on the template substrate; the maximum sequence length of “polymerized” bound B monomers increases with increasing the number of bound B monomers present in a single substrate. Long consecutive sequences of B bound monomers in the A–B copolymer are formed when the B bound monomers are immobilized in space in high densities.}, number={6}, journal={MACROMOLECULES}, author={Datta, Preeta and Genzer, Jan}, year={2013}, month={Mar}, pages={2474–2484} }

We seek to understand how spatial confinement affects the system dynamics and overall polymerization kinetics. We find that with increasing confinement of the system, the front propagation velocity decreases and the nearly “parabolic” front profile flattens out. While in bulk or unconfined systems the convective heat and mass transfer effects are responsible for higher heat generation rates and higher temperature gradients, leading to faster front propagation, the convection is significantly suppressed in highly confined systems. Consequently, a smaller number of radicals are generated, resulting in a slower propagation step and long polymer chains.}, number={12}, journal={POLYMER CHEMISTRY}, author={Datta, Preeta and Efimenko, Kirill and Genzer, Jan}, year={2012}, month={Dec}, pages={3243–3246} }
