Atomic Force Microscopy data of Poly-3-hydroxybutarate and Poly-3-hydroxyvalerate films

<p>This dataset consists of atomic force microscopy (AFM) scans of &nbsp;<em><strong>Polyhydroxyalkanoate</strong></em> films in text (.txt) format as well as their corresponding previews in (.png) format.&nbsp;</p> <p>The surfaces of <strong><em>Poly-3-hydroxybutarate (P3HB [100%])</em></strong> and <em><strong>Poly-3-hydroxyvalerate (P3HB-co-P3HV) [90% :10%]) </strong></em>of six film thicknesses, three scan sizes (5&micro;m, 10&micro;m and 30&micro;m) and three unique scan areas have been scanned with AFM equipment from NT-MDT spectrum instruments.</p> <p>This dataset has been used in the work <a href="../doi/10.5281/zenodo.10621269" target="_blank" rel="noopener">10.5281/zenodo.10621269</a> within which the scan data has been divided into multiple sub-pools for experimentation.
