Claim:
1. A method of preparing a cohesive carbon assembly comprising: (a) obtaining a carbon starting material in the form of powder, particles, flakes, or loose agglomerates, (b) dispersing the carbon starting material in an organic solvent comprising toluene, o-dichlorobenzene (ODCB), isopropyl alcohol (IPA), N,N-dimethylformamide (DMF), benzene, chlorobenzene, m-dichlorobenzene, 1,2,4-trichlorobenzene, bromobenzene, m-dibromobenzene, o-dibromobenzene, o-xylene, m-xylene, p-xylene, 1,2-dichloroethane, 1,2-dibromoethane, chloroform, formamide, N-methylformamide, N-vinylformamide, N-(phenethyl)formamide, N,N-diethylformamide, N,N-bis(1-methylethyl)formamide, dimethyl sulfoxide, or any combination thereof, in a prescribed ratio to form a dispersion, (c) applying the dispersion to a hydrophobic surface, and (d) substantially removing the organic solvent in a controlled manner to form a cohesive carbon assembly on the hydrophobic surface, wherein the hydrophobic surface comprises a dimethyl organosilane, a fluorinated dimethyl organosilane, a fluorinated polymer, or Teflon.
