Supporting information for "Cosolvent effects on the structure and thermoresponse of a polymer brush: PNIPAM in DMSO-water mixtures"

This deposition contains the data and analysis (Jupyter notebooks) detailed in "Cosolvent effects on the structure and thermoresponse of a PNIPAM brush”. All Jupyter notebooks have also been converted into PDF files for ease of viewing. All data and code (notebooks) required to reproduce the analysis can be found within the “supporting_data_analysis.zip” archive. This archive contains three sub-directories: FTIR FTIR transmission data of binary DMSO-water mixtures as a function of solvent composition. FTIR deconvolution was performed using software readily available at https://github.com/haydenrob/spec_deconv. Ellipsometry Data directory containing all raw ellipsometry data. “refellips_Spectroscopic_SL.ipynb” notebooks to reproduce the analysis of a hydrated (solid-liquid) polymer brush. Relevant plotting tools can be found in the refellips repo. A spatial map of the polymer brush used for spectroscopic ellipsometry data analysis: “surface_map.png”. “Ellipsometry_logistical_fitting.ipynb” notebook and “DMSO_6mol_results.csv” file for the demonstration of the extraction of a thermotransition temperature from an ellipsometry dataset. Neutron_reflectometry Data directory containing all relevant reduced reflectivity profiles from the Platypus reflectometry at ANSTO. “refnx_dry.ipynb” and “refnx_solvent.ipynb” notebooks required to reproduce the analysis pertaining to a dry polymer brush and a solvated brush, respectively. Additional code required to model the hydrated polymer brush and various plotting tools can be in the refnxtoolbox repo.
