Outline of Final Research Achievements

In this work, we investigated frictional properties of a polyelectrolyte, NaPSS, brush in water that is strongly stretched away from its substrate by using SPM in order to elucidate the molecular mechanism of its low frictional properties. The friction force was proportional to sliding distance under small displacement conditions. A larger sliding intensity resulted in smaller and displacement-independent frictional force. This properties indicated physical adsorption between the stretched polymer chains and the rubbing object, kantilever tip, that makes the detected frictional force from lateral elasticity of the polymers in the former conditions and their desorption force from the sliding object in the latter.
