US 2015/0133013 A1 · WATERPROOF APERTURED SURFACES OR MATERIALS USING NANOPARTICLE HYDROPHOBIC TREATMENTS

Abstract

A method of manufacturing waterproof apertured materials or surfaces using nanoparticle hydrophobic compositions and treatments, and preferably superhydrophobic compositions and treatments, wherein apertures of a size that would normally render the surface or material water-permeable may be provided in the surface or material. The method comprises determining the extent of the hydrophobic field that extends beyond the physical edge of a particular treated intersecting member interwoven to form the material to determine the allowable size of an aperture, such that the extended hydrophobic field present on the intersecting members surrounding an aperture will be sufficient to prevent surface wetting and water permeability by fully overlapping the aperture or by presenting a reduced area effective aperture that precludes passage of water.

A method of manufacturing an apertured waterproof mesh material comprising the steps of:

interweaving intersecting members to form a mesh material comprising apertures of a size such that said mesh material is not waterproof;
treating said intersecting members with a nanoparticle hydrophobic or superhydrophobic composition to create a hydrophobic field extending beyond said intersecting members and into each of said apertures such that the effective size of each of said apertures is reduced to a size that precludes passage of water through said apertures.
