Title: Conversion of additively manufactured organic polymer parts to substantially pure carbon

Abstract

In one embodiment, a method includes creating a three-dimensional, carbon-containing structure using an additive manufacturing technique and converting the three-dimensional, carbon-containing structure to a substantially pure carbon structure. Moreover, the substantially pure carbon structure has an average feature diameter of less than about 100 nm. In another embodiment, a product includes a substantially pure carbon structure having an average feature diameter of less than about 100 nm. In yet another embodiment, a product includes an aerogel having inner channels corresponding to outer walls of a three-dimensional printed template around which the aerogel was formed. In addition, the inner channels have an average feature diameter of less than about 100 nm.
