  • Highly metallic, hydrophilic, polymer-free carbon nanotube (CNT) thin sheet and uses thereof
    Patent number: 11873222
    Abstract: The present disclosure is directed to the preparation of highly metallic, hydrophilic, polymer-free carbon nanotube (CNT) thin sheets with high tensile strength. The densified CNT sheet has reduced pore sizes, increased tensile strength, and improved electrical conductivity. The disclosed CNT materials can be used as filtration membranes with little or no propensity toward surface fouling. Such densified CNT sheets are also useful as superior electromagnetic interference (EMI) shielding materials.
