Genzer Research Group How does substrate geometry affect the surface-initiated controlled polymerization? Jan Genzer (Department of Chemical & Biomolecular Engineering) Objective: Investigate the effect of the substrate geometry and solution conditions on the “grafting from” polymerization from solid substrates Methods: computer simulations Monomers Polymers Polymer chain ends good solvent poor solvent s=0.08 s=0.16 Findings: In living polymerizations molecular weight polydispersity increases with increasing degree of confinement. Confinement either due to the presence of a surface or due to poor solvent quality. Monodisperse polymer brushes cannot be prepared by “grafting from” polymerization. s=0.44
