Entropic Surface Segregation from Athermal Polymer Blends due to Conformational Asymmetry
This is a modified version of my 2022 APS March Meeting talk.
APS talk URL: https://meetings.aps.org/Meeting/MAR2...
Other, related, talk: https://www.dpg-verhandlungen.de/year...
Lattice paper: https://doi.org/10.1021/acs.macromol....
Off-lattice paper: https://doi.org/10.1021/acs.macromol....
Off-lattice code: https://github.com/PolymerTheory/TanS...
Correction: There was an error in the lattice calculations. It has been corrected and the results have been reproduced and published. See https://pubs.acs.org/doi/10.1021/acs....
The off-lattice calculations are unaffected and the main conclusions of the lattice calculations are the same, but there are some quantitative changes to the results.
