Abstract The friction properties of two kinds of self--asssembled
monolayers with the same length of molecule chain and
different functional groups were investigated. The effects of load
and sliding velocity on the friction characteristics of SAMs were
analyzed. The results indicate that the stronger the chemical
activity of functional group in self--assembled molecules is,
the more remarkable the SAMs cluster topography characteristics are.
The friction forces increase with increasing the loads for these two
self--assembled molecules with short chain. However, the effects of
sliding velocity on the friction force appear when the chemical
reactivity of functional group in self--assembled molecules is
strong enough. The friction forces decrease markedly after the
formation of SAMs with stable structure, which exhibits anti--friction
effect. The anti--friction effect disappears if the load rises to a
threshold for SAMs with stronger active functional group. The stronger
the chemical activity of functional group in self-assembled molecule is,
the larger the friction forces are.
