1. A method for producing a reversible hemiaminal or aminal gel composition for use in 3D printing, the method comprising the steps of:
preparing a liquid precursor composition, the liquid precursor composition operable to remain in a first liquid state at about room temperature, where the liquid precursor composition comprises:
an organic amine composition;
an aldehyde composition;
a polar aprotic organic solvent; and
a carbon nanomaterial;
heating the liquid precursor composition to transition from the first liquid state to a gel state;
transitioning the gel state to a second liquid state comprising adding a metal salt composition to the gel state; and
3D printing a solid carbon nanomaterial object comprising a solid printed gel from the second liquid state with a pre-determined orientation for the carbon nanomaterial.
