WebBoth coated and uncoated fibers were tested for their DC conductivity, and the results showed a clear difference between the two. From a highly insulating state, it transitions to about 0.1 S/cm. Both the tensile strength and modulus seemed to rise, going from 0.5 MPa to 2.5 MPa and from 0.04 MPa to 0.4 MPa, respectively. Webgood electrical conductor and a good thermal conductor in the x-y plane. The bonding between the layers is Vander Waals bonding, so the carbon layers can easily slide with respect to one another; graphite is an electrical insulator and a thermal insulator perpendicular to the layers. Due to the difference between the in-plane and out-of-plane
