Abstract
The present disclosure relates to active particle-enhanced membrane and methods for making and using the same. In some embodiments, a breathable membrane includes a base material solution and active particles. The active particles incorporated in the membrane may improve or add various desirable properties to the membrane, such as for example, the moisture vapor transport capability, the odor adsorbance, the anti-static properties, or the stealth properties of the membrane. In some embodiments, the base material may exhibit water-proof properties when converted into non-solution state, and thereby result in a water-proof membrane. In some embodiments, the active particles may be protected from losing activity before, during, or after (or any combination thereof) the process of producing the membrane. The membrane may be applied to a substrate, or may be used independent of a substrate.
