4th PHASE SHIELD
4TH PHASE SHIELD
Polymer-free densified carbon nanotube (DCN) sheet is the best in the class and a platform material.
DCN sheets withstand high temperature, resist against organic solvents and strong acids and bases.
DCN sheets are highly conductive with electric conductivity reaching that of mercury (1 x 10^6 S/m).
DCN sheets are superior electromagnetic interference (EMI) shielding material and can find applications in defense, aerospace, automotive and consumer electronics markets. They can also find use as soft electrodes.
SPACE, SATELLITE COMMUNICATIONS, DEFENSE, CONSUMER ELECTRONICS AND AUTOMOTIVE MARKETS
Most Lightweight with Areal Density of as low as ~0.5 g/m^2
Very Thin (2-4 micrometers)
Compatible with Extreme Temperatures, High Humidity, and Strong Acids/Bases
Flexible, Durable and Robust
Here we show a 30 cm x 30 cm CNT sheet of less than 5 micrometers in thickness and less than 0.75 g in mass to shield the electromagnetic signal for making a phone call. When the phone is wrapped in the sheet, it cannot pick up any signal to ring.
