Abstract
Description
The first Igor Pro file contains the post-processed data from stitched AFM images originally acquired in PeakForce Tapping mode. The images were imported and analyzed using Gwyddion, where cross-sectional analysis was performed on the height, adhesion, dissipation, and Young’s modulus channels. Each cross-section was averaged with 128 adjacent profiles to improve signal quality. The height profile was further normalized to its initial value of 486 nm, corresponding to the reference condition at 5.7% relative humidity (RH). This file contains both the raw channel data and the processed, normalized profiles used for further analysis.
The second contains force–distance data extracted from PeakForce Tapping mode measurements on the polymer edge, acquired during one-line mode scans at controlled humidity conditions. Specifically, it includes two representative force–distance curves recorded at 70% and 90% relative humidity (RH). The file provides the raw and processed force data used to illustrate humidity-dependent changes in surface mechanical response, such as adhesion and stiffness. These curves were selected for their clarity and typical behavior and were plotted for direct comparison to visualize the impact of RH on the tip–sample interaction.
