4th PHASE SHIELD

Densified CNT Sheet

ABOUT
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.

About

WHAT IS DCN?

4th Phase Technologies manufactures densified carbon nanotube (DCN) sheets from raw pristine carbon nanotube (CNT) sheets. Extensive CNT bundling and alignment result in DCN's high tensile strength and high electric conductivity.

WHAT SETS US APART?

4th Phase Technologies approaches this technological challenge by developing a proprietary process to purify CNTs in raw pristine CNT sheets without relying on harsh and corrosive chemical treatment, and densify purified CNTs without polymer binders.

APPLICATIONS

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

VIDEO

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.
