Supporting information for "Underscreening in concentrated electrolytes: Polyelectrolyte brushes exhibit re-entrant swelling behaviour"

This deposition contains the data and analysis (Jupyter notebooks) detailed in "Underscreening in concentrated electrolytes: Polyelectrolyte brushes exhibit re-entrant swelling behaviour". 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.zip” archive. This archive contains three sub-directories: Spectroscopic_ellipsometry Data directory (data_files) containing all raw ellipsometry data. “PMETAC_wet_analysis.ipynb” notebooks to reproduce the analysis of a hydrated (solid-liquid) polymer brush. Further relevant plotting tools can be found in the refellips repo. “PMETAC_dry.ipynb” notebook to reproduce the analysis of the dry polymer film and create the areal maps. Neutron_reflectometry Data directory (NamedData) containing all relevant reduced reflectivity profiles from the Platypus reflectometry at ANSTO. “NR_dry.ipynb”, “NR_Solid-Liquid.ipynb” notebooks required to reproduce the analysis pertaining to a dry polymer brush and a solvated brush, respectively. “NR_Solid-Liquid_corefine.ipynb” notebook for reproducing the simultaneous optimisation of the PMETAC brush in D2O and H2O: co-refinement. Additional code required to model the hydrated polymer brush and various plotting tools can be found in the refnxtoolbox repo and the refnx repo. nSCFT Files containing the polymer, ion, and solvent VF profiles from nSCFT calculations.本存档包含刊载于《浓电解质中的欠屏蔽效应：聚电解质刷呈现再入溶胀行为》一文的全部实验数据与分析代码（Jupyter笔记本，Jupyter Notebook）。为方便查阅，所有Jupyter笔记本均已转换为PDF格式。 所有可复现该分析所需的数据与代码（笔记本文件）均可在"supporting_data.zip"压缩包中获取。该压缩包共包含三个子目录： ### Spectroscopic_ellipsometry 1. `data_files`数据文件夹：存储所有原始椭偏实验数据。 2. `PMETAC_wet_analysis.ipynb`：用于复现水合（固-液界面）聚合物刷的分析流程，相关绘图工具可在`refellips`代码仓库中获取。 3. `PMETAC_dry.ipynb`：用于复现干燥聚合物薄膜的分析过程，并生成面分布图像。 ### Neutron_reflectometry 1. `NamedData`数据文件夹：存储ANSTO的Platypus反射仪采集的全部约化反射率剖面数据。 2. `NR_dry.ipynb`、`NR_Solid-Liquid.ipynb`：分别用于复现干燥聚合物刷与溶剂化聚合物刷的相关分析。 3. `NR_Solid-Liquid_corefine.ipynb`：用于复现PMETAC刷在重水（D₂O）与轻水（H₂O）中的同时精修优化分析，即共精修。 4. 用于建模水合聚合物刷的额外代码与各类绘图工具，可在`refnxtoolbox`代码仓库及`refnx`代码仓库中获取。 ### nSCFT 存储来自nSCFT计算的聚合物、离子与溶剂的体积分数（VF）分布曲线。
