Wetting and evaporation behaviors of argon nanodroplets on smooth and rough substrates are studied using molecular dynamics simulations. Effects of interaction energy between solid and argon atoms on wetting and evaporation and differences between nanodroplets on smooth and rough substrates have been investigated. The results show that for both smooth and rough substrates, as the interaction energy between solid and argon atoms increases, the contact angle and total evaporation increase. For rough substrates, the variations of contact angle and contact radius during evaporation progress are much more complex and the total evaporation is much larger than that of smooth substrates.
