Abstract
A membrane for collecting airborne particles, the membrane taking the form of a strip composed of a matrix formed from a mixture of a polymer and of a filler that is made of an electrical conductor, a hydrophilic layer for collecting particles, on which layer is deposited said matrix so as to form at least one composite layer, the membrane including at least one region obtained via a surface treatment of the hydrophilic layer.
Claims20
A membrane for collecting airborne particles, wherein the membrane includes a strip composed of:
- a matrix formed from a mixture of a polymer and of a filler that is made of an electrical conductor, and
- a hydrophilic layer for collecting particles, on which is deposited said matrix so as to form at least one composite layer,
- said membrane comprising at least one region obtained via a surface treatment of said hydrophilic layer,
- wherein the hydrophilic layer has a total area and comprises at least a first region, referred to as a collection region, obtained via said surface treatment in a first portion of the total area and at least a second region produced in a second portion of the total area, the hydrophilic laver having a first thickness in the collection region and a second thickness in the second region, the first thickness being smaller than the second thickness.
