Reversible stepwise condensation polymerization with cyclization: strictly alternating co-polymerization and homopolymerization based upon two orthogonal reactions
Michael Lang, Kiran Suresh Kumar
In a preceding work [M. Lang, K. Kumar, A simple and general approach for reversible condensation polymerization with cyclization, Macromolecules 54 (2021) 7021], we have introduce…
Testing the physics of knots with a Feringa nanoengine
Michael Lang, Cornelia Schuster, Ron Dockhorn +2
We use the bond fluctuation model to study the contraction process of two polymer loops with segments that are connected each to the bottom and top part of a Feringa engine. Th…
Competing exchange and irreversible reactions in a linear co-polycondensation lead to a broad composition window where tunable high molecular weight polymers can be prepared
Michael Lang, Frank Böhme
A co-polycondensation reaction is discussed analytically and by Monte-Carlo simulations where two reactive units compete for reactions with an alternating third reactive unit, wher…
Fluctuation driven height reduction of crosslinked polymer brushes
M. Lang, M. Hoffmann, M. Werner +2
We study the changes in the conformations of brushes upon the addition of crosslinks between the chains using the bond fluctuation model. The Flory-Rehner model applied to uni-axia…
Excluded volume effects in polymer brushes at moderate chain stretching
Dirk Romeis, Michael Lang
We develop a strong stretching approximation for a polymer brush made of self-avoiding polymer chains. The density profile of the brush and the distribution of the end monomer posi…
Arm retraction dynamics in dense polymer brushes
Michael Lang, Marco Werner, Ron Dockhorn +1
Large scale Monte Carlo simulations of dense layers of grafted polymer chains in good solvent conditions are used to explore the relaxation of a polymer brush. Monomer displacement…
