Abstract
A method of manufacturing waterproof apertured materials or surfaces, and such materials or surfaces, using nanoparticle hydrophobic compositions and treatments, and preferably superhydrophobic compositions and treatments, which possess apertures retaining breeching members possessing liquid wicking properties which would normally render the surface or material water-permeable. By treating the breeching members with the nanoparticle hydrophobic or superhydrophobic compositions, a hydrophobic field extending from the breeching member is created, such that the extended hydrophobic field precludes passage of liquid through the apertures by wicking or capillary action.
Claims20
A method of preventing water passage through an aperture in a waterproof material when a breeching member is present in the aperture, the method comprising the steps of:
- treating said breeching member with a nanoparticle hydrophobic or superhydrophobic composition to create a hydrophobic field extending beyond said breeching member;
- and
- inserting said breeching member through said aperture;
- whereby said hydrophobic field precludes passage of liquid through said aperture.
A method of manufacturing an apertured waterproof material having a breeching member passing through an aperture, the method comprising the steps of:
- treating said breeching member with a nanoparticle hydrophobic or superhydrophobic composition to create a hydrophobic field extending beyond said breeching member;
- and
- inserting said breeching member through said aperture;
- whereby said hydrophobic field precludes passage of liquid through said aperture.
An apertured waterproof material having a breeching member passing through an aperture comprising:
- a waterproof material, said waterproof material comprising one or more apertures;
- a breeching member passing through each said one or more apertures, each said breeching member having been treated with a nanoparticle hydrophobic or superhydrophobic composition to create a hydrophobic field extending beyond said breeching member;
- whereby said hydrophobic field precludes passage of liquid through said one or more apertures.
