  • Patent number: 12257819
    Abstract: In one embodiment, a thin, lightweight, flexible, strong multi-layer barrier fabric is provided that offers extended breakthrough time against hazardous materials. The multi-layer barrier fabric is arranged as a layer stack that includes an inner layer of facing fabric, an adsorbent layer of adsorptive fabric, a barrier layer of low-permeability fabric and an outer layer of facing fabric. The facing fabric provides tensile strength. The adsorptive fabric and the low-permeability fabric interact synergistically. The barrier layer improves capture effectiveness of the adsorbent layer by both slowing down the hazardous material to increase its residence time in the adsorbent layer and decreasing the escape probability of stray molecules of hazardous material that are not initially intercepted by the adsorptive fabric. The adsorbent layer improves barrier effectiveness of the barrier layer by reducing the concentration of hazardous material challenging the low-permeability fabric of the barrier layer.

  • Patent number: 12145848
    Abstract: Techniques are described for transferring nanofiber forests using transfer films that either lack a conventional adhesive at the substrate—nanofiber forest interface or that include a diffusion barrier that prevents diffusion of adhesive molecules (or other polymer molecules mobile at ambient temperatures) into the nanofiber forest. These techniques can be applied to single layer nanofiber forests or stacks of multiple nanofiber forest. By selecting the bond strength between the nanofiber forest and the transfer films, the nanofibers can be aligned in a common direction that includes, but is not limited to, perpendicular to a substrate or transfer film.
