HIERARCHICAL THERMOPLASTIC SURFACE TEXTURES FORMED BY PHASE TRANSFORMATION AND METHODS OF MAKING

摘要

Method for treating thermoplastic to make a surface thereof superhydrophobic. The method includes exposing the thermoplastic to a specific solvent for a selected time period. It is preferred that the treatment time be in the range of one minute to approximately five hours and more preferably in the range of one minute to 15 minutes. Thermoplastics and solvents having a similar solubility parameter interact with one another to form hydrophobic hierarchical surfaces.
