Chemical Modification of Diamond Surface with Long Alkyl Chain Containing Carboxylic Acid in Benzoyl Peroxide Containing Organic Solution

抄録

The chemical reactivity of a hydrogenated diamond surface with carboxylic acid in benzoyl peroxide containing an organic solution was investigated. Stearic acid, which has a long alkyl chain in its chemical structure, was reacted with a hydrogenated diamond surface by using benzoyl peroxide. The surface condition treated with stearic acid was shown to be stable against chemical solvents. By increasing the amount of the addition of stearic acid added, the functional group derived from the stearic acid was introduced on the diamond surface more preferentially than the functional group derived from the benzoyl peroxide.
