In the work related to this dataset, we show the effect of polydispersity on polymer solutions and melts near a solid surface. We derived closed-form analytical equations, which were validated using lattice Scheutjens-Fleer self-consistent field (SF-SCF) computations. In the dataset, the input and output files of these calculations are included, organized per figure. The accompanying python script provides all the code to recreate the figures in the paper, where the SF-SCF data is compared to analytical expressions.
