NCSU show conductive Kevlar by Tungsten ALD coating

As reported by Laboratory Equipment: A group of North Carolina State Univ. researchers is exploring novel ways to apply semiconductor industry processes to unique substrates, such as textiles and fabrics, to "weave together" multifunctional materials with distinct capabilities.

During the AVS 61st International Symposium & Exhibition, being held November 9-14, 2014, in Baltimore, Maryland, the researchers will describe how they were able to weave high-strength, highly conductive yarns made of tungsten metal on Kevlar — body armor material — by using atomic layer deposition (ALD), a process commonly used for producing memory and logic devices.

The group's tungsten-on-Kevlar yarns are expected to find applications in multifunctional protective electronics materials for electromagnetic shielding and communications, as well as erosion-resistant antistatic fabrics for space and automated technologies
