Abstract
Discontinuities, edge sites and grain boundaries in carbons, the primary locations of instabilities for oxidative corrosion and degradation, are prepared by preoxidation to form carbon-oxides followed by highly selective and relatively mild fluorination to specifically substitute carbon-oxygen functionality with stable carbon-fluorine groups. The novel fluorinated carbons have enhanced chemical and/or electrochemical stabilities to corrosion, improved hydrophobicity, lubricating properties, etc.
