Aspects described herein are directed to compositions, systems, and methods of manufacturing a polymer-based construction material comprising polymeric resin, filler such as calcium carbonate (CaCO.sub.3), and titanium oxide (TiO.sub.2). A surface of the polymer-based construction material may be treated such that the surface energy is increased from the material's inherent value to a predetermined value of at least 40 dynes/cm.sup.2. Further, the surface energy of the treated surface may persist within 20% of the predetermined value for at least three days.

A liquid-repellent plastic molded body 1 according to the present invention has a liquid-repellent surface. The liquid-repellent surface has a re-entrant structure surface formed by an array of pillars 20 each having a head portion 20a with an enlarged diameter. At least a part of the re-entrant structure surface has a fluorine-containing surface in which fluorine atoms are distributed.

A method for plasma treating a surface of a first substrate is disclosed. The method may comprise generating a plasma flume using a plasma treatment device having a nozzle. The plasma flume may emanate through a flume aperture of the nozzle at an emanation angle of about 5 degrees or less. The emanation angle may be defined as an angle between a central axis of the nozzle and a central axis of the flume aperture. The method may further comprise plasma treating the surface of the first substrate with the plasma flume by scanning the plasma flume over the surface of the first substrate. The first substrate may be one of a consolidated thermoplastic material and a cured thermoset material.
