Wetting phenomena are extensively studied from a experimental to a theoretical point of view (see Refs. [1, 2] for reviews) and much attention has been drawn recently to the case of the dynamics of liquid droplet under evaporation [3-9]. In this paper, we propose a model of a contact line under evaporation and total wetting conditions taking into account van der Waals interactions and the divergent nature of evaporation near the border of the liquid evidenced by Deegan et al. [3]. We apply this result to study the dynamics of an evaporating droplet in complete wetting situation.
