Supporting Information for "Solvent modulated specific ion effects: PNIPAM brushes in non-aqueous electrolytes"

This deposition contains the data and analysis (Jupyter notebooks) detailed in Solvent modulated specific ion effects: PNIPAM brushes in non-aqueous electrolytes. 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:

• Ellipsometry
  • Data directories containing all raw ellipsometry data for the ‘thick’ and ‘thin’ PNIPAM brushes.
  • Spatial maps of the polymer brush used for spectroscopic ellipsometry data analysis: “surface_map.png”.
  • “refellips_Spectroscopic_SL.ipynb” notebook to reproduce the analysis of the hydrated (solid-liquid) ‘thin’ polymer brush. Relevant plotting tools can be found in the refellips repo.
  • “Ellipsometry_logistical_fitting.ipynb” notebook and “water_results.csv” file for the demonstration of the extraction of a thermotransition temperature from an ellipsometry dataset. 
  • “refellips_Spectroscopic_SL_VFP.ipynb” notebook to reproduce the analysis of the hydrated (solid-liquid) ‘thick’ polymer brush.
• Neutron_reflectometry
  • Data directory containing all relevant reduced reflectivity profiles from the Platypus reflectometer 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.
