Abstract
Disclosed is a bioprotective composite material. The bioprotective composite material includes a fiber network support, a seed layer for covering a surface of the fiber network support, and pyroelectric nanostructures protruding from the seed layer. Such bioprotective composite material generates a pyro-potential by a temperature change, and thus, has improved antibacterial and antiviral activities.
