摘要：

This paper presents a systematic study of de-ionized water droplets impact on five different self-assembled monolayer surfaces: octadecanethiol, hexadecanethiol, dodecanethiol, heptanethiol and pentanethiol. Our data for the maximum spreading diameter of water impacting on these surfaces were compared with those predicted from literature models. Of the models selected, the model [M. Pasandideh-Fard, S. Chandra, J. Mostaghimi, Phys. Fluids 8 (1996) 650] was modified and the results yielded a least mean error of 7.55 1.73% in the determination of the maximum spreading diameter, which is among the best from those selected.
