Poly brushes adhesive forces

When stimuli-responsive polymers are attached to a surface, changes in the physicochemical properties of the surface layer that result from an external stimulus can be assessed by AFM in situ. Micropattemed thermoresponsive polymers, such as poly(A-isopropylacrylamide) (PNIPAm), were characterized via AFM height imaging and the brush adhesiveness measured by force spectroscopy during... 

Many workers have examined the effect of surfactants and polymers adsorbed on mica. For example, polymers such as poly(vinyl pyridine) and its copolymers have been adsorbed on mica and their interfacial interactions measured in liquid media. Forces measured between these surfaces are of much longer range and provided some evidence for the brush conformation of polymers. Other workers have used industrially generated polymer films mounted directly to the glass lenses in the SFA and examined their adhesion...
