Evaporative Morphology Tuning of Conducting Polymer Films Under Controlled Vacuum Conditions.

ABSTRACT: The evaporation of drops on solid surfaces is a ubiquitous natural phenomenon, and their dynamics play a pivotal role in many biological, environmental, and industrial processes. However, the complexity of the underlying mechanisms has largely confined previous studies to liquid drop evaporation under atmospheric conditions. In this study, the first comprehensive investigation of the evaporation dynamics of conducting polymer-containing drops under controlled vacuum environments is presented. Utilizing high-speed imaging of a drop within a vacuum chamber, it is observed that the evaporation of a sessile drop under vacuum conditions unfolds through four distinct stages: Constant Contact Radius (CCR), Constant Contact Angle (CCA), Increasing Contact Angle (ICA), and Stick and Slip (S&S) mode
