A carbon nanopipe comprising a durable graphitizable carbon wall of tunable thickness of about 10-500 nm formed by exposing a silica fiber network to a carbon precursor vapor and thereby depositing a carbon film onto the silica fiber network at a temperature suitable for complete pyrolysis of the carbon precursor and removing the silica fibers. The atmosphere of the step of depositing is controlled by a two-stage gas manifold wherein stage 1 purges the reaction chamber with pure argon and stage 2 introduces the carbon precursor.

Carbon nanopipes and ductwork with nanometric walls and methods of making the same

An article having: a nonconductive fiber and a RuOcoating. A method of: immersing a nonconductive article in a solution of RuOand a nonpolar solvent at a temperature that is below the temperature at which RuOdecomposes to RuOin the nonpolar solvent in the presence of the article; and warming the article and solution to ambient temperature under ambient conditions to cause the formation of a RuOcoating on a portion of the article. An article having: a nonconductive fiber and a coating. The coating is made by electroless deposition, sputtering, atomic-layer deposition, chemical vapor deposition, or physical vapor deposition.

[object Object]

A method of making a carbon nanopipe and ensemble of carbon nanopipes, comprising the steps of flowing a carbon precursor over silica fibers and thereby depositing a durable graphitizable carbon coating of tunable thickness of about 10-500 nm onto the silica fibers and etching away the silica fibers to yield a three-dimensional mat of electronically networked, hollow carbon tubules. A carbon nanopipe comprising a durable graphitizable carbon wall of tunable thickness of about 10-500 nm formed by exposing a silica fiber network to a carbon precursor vapor and thereby depositing a carbon film onto the silica fiber network at a temperature suitable for complete pyrolysis of the carbon precursor and removing the silica fibers.
