Biocidal infused composite fabric for cabin interiors
A biocidal composite wall or surface fabric installable within an aircraft cabin or other vehicle interior space includes a flexible woven layer. The woven layer is treated on its outer surface with a biocidal polymer coating. For example, the polymer coating may incorporate biocidal microcapsules or nanocapsules configured for controlled release of biocidal compounds in response to physical contact or other stimuli. The released biocidal compounds compromise or kill microbial compounds deposited on the outer surface, e.g., via physical contact by passengers or crewmembers. The woven layer includes additional biocidal molecules incorporated into its fibers and strands, the biocidal molecules capable of biocidal action in response to contact with the fabric.
1. A biocidal infused composite fabric installable on an interior surface of a mobile platform, the fabric comprising:
a flexible substrate woven from a yarn comprising a plurality of fibers woven into a plurality of strands, the flexible substrate treated on an external surface with a polymer coating,
the polymer coating comprising:
polymer chain molecules; and
one or more biocidal compounds configured for sustained release of one or more biocidal agents upon contact with a microbial substance, wherein the one or more biocidal compounds comprise one or more nanocapsules less than 100 nm in diameter disposed within the polymer coating, each nanocapsule comprising a shell enclosing the one or more biocidal compounds and configured for controlled release of the one or more biocidal compounds in response to an external stimuli, wherein the one or more biocidal agents include one or more polycationic compounds.
2. The biocidal infused composite fabric of claim 1 , wherein:
the one or more biocidal molecules are crosslinked to the one or more polymer chain molecules.
3. The biocidal infused composite fabric of claim 1 , wherein the polymer coating includes at least one flame resistant compound.
4. The biocidal infused composite fabric of claim 1 , wherein the one or more biocidal compounds and the one or more biocidal molecules further includes a molecule selected from a group including: a metal salt, a metal oxide, or a quaternary ammonium compound.
5. A biocidal infused composite fabric of claim 1 , wherein a pressure upon the polymer coating triggers a diffusion of the one or biocidal compounds from the biocidal nanocapsules.
