Enhanced Coffee-Ring Effect via Substrate Roughness in Evaporation of Colloidal Droplets

The analysis of dried drop patterns has various applications in research fields like archeology, medical practice, printing, and so on. In this paper, we studied the evaporation and pattern formation of polytetrafluoroethylene (PTFE) colloid droplets on smooth substrate and rough substrates with dif...
