摘要：

Free energy was measured for the surface of regular aligned closest hexagonal packed -CF3 groups. n-Perfluoroeicosane was vapor deposited onto glass, which gave epitaxially grown single-like crystallites with their molecular axes perpendicular to the glass surface. The dynamic contact angle of water on its surface was 119 degrees, which corresponds to a surface free energy of 6.7 mJ/m(2). This value is considered to be the lowest surface free energy of any solid, based on the hexagonal closed alignment of -CF3 groups on the surface.
