This dataset comprises the measurements of interaction Gibbs free energy versus surface separation presented in manuscript entitled "Proline enhances repulsive double-layer forces between charged particles". Data for interaction Gibbs free energy and surface separation are presented for each proline and/or KCl solution composition, as described in the manuscript and supplemental material.
Each folder contains the data for a specific solution composition. All folders contain data obtained from approach of the surfaces, and where necessary, data from one or more surface retractions.
Each .csv file displays the surface separation in nm (column A) and the interaction Gibbs free energy in mJ m^-2 (column B).
