Abstract
A methodology is provided for generating hydrophobic superhydrophobic, oleophobic and/or superoleophobic surfaces. Compositions of matter made of a substrate having deposited on a surface thereof (e.g., by thermal evaporation) hydrocarbon waxes, including fluorinated waxes, are disclosed. Process of preparing such compositions of matter and articles of manufacturing incorporating such compositions are also disclosed. Further disclosed are articles of manufacturing and methods which are useful in inhibiting, reducing and/or retarding biofilm formation, and which include applying waxes (e.g., by thermal evaporation) on a surface of the articles.
