A flame deposition method is disclosed for forming hydrophobic nanotextured surfaces with improved adhesion and durability for long-term use. The method according to present disclosure can produce nanotextured surfaces with contact angles greater than 140°. Coatings thus prepared exhibit enhanced durability, maintaining water contact angles of greater than 120° after approximately 200,000 abrasion cycles using a cloth wipe resistance test.

Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. Also described are systems for performing the various processes.
