Fig. 1: The formation and stability of PFCA molecular clusters with different chain lengths were investigated at a concentration of 100 uM.

Fig. 1

A show the PFCA clusters with different chain lengths obtained on the surface of mica flakes. B show the histograms of the distribution of the heights of the PFCA clusters on mica, where the relative frequency (%) of clusters within defined height intervals is calculated with respect to the total measured height distribution. C show the F-atom density fields of PFCA molecular clusters of different sizes, representing the spatial density of fluorine atoms (g·cm⁻³). (The first to fourth rows in the image are as follows: PFBA clusters; PFHxA clusters; PFOA clusters; PFDA clusters).
