Superhydrophobic surface, polycarbonate crystallization
Large range of manufacturing, industrial, agricultural and household applications.
Many surface applications require superhydrophobicity for better performance.
Superhydrophobic surfaces possess many beneficial properties, such as self-cleaning and water-repellency. These properties make them useful in a large range of manufacturing, industrial, agricultural, and household applications. In this invention, superhydrophic polycarbonate (including polycarbonate sheets and particles) were prepared by acetone treatment. Acetone modifies polycarbonate to micro- and nano-level spherulitic structure. The spherulitic structure produced surface roughness and resulted in surfaces exhibiting superhydrophobic properties.
Acetone treatment greatly increases the crystallization of superhydrophobic polycarbonate.
