SFM-Based Stiffness Mapping in Force Modulation Microscopy (FMM) Mode... 

Force Modulation Microscopy A further extension to AFM imaging is that of force modulation microscopy (FMM) which characterizes the sample s mechanical properties while simultaneously obtaining the surface topographic information. 

FMM Force Modulation Microscopy Biosensors Using Atomic Force Microscopes... 

It was previously shown that atomic force microscopy, AFM, and force modulation microscopy, FMM, can bring novel informations concerning the elastic and the viscoelastic properties of PP/EP resins at the microscopic level. They enabled the mapping of EP rubbery nodules distribution and the explanation of the macroscopic behavior of these resins (e.g. differences in the impact resistance) (5). Moreover, recent works showed that the use of AFM techniques (force-curves and force-modulation measurement, FMM cartography) can be used to characterize the surface elastic properties of PP/EP blends (6). Especially, these studies demonstrated that I M can map the surface and the subsurface distribution of EP nodules.

Figure 3.28. Schematic of the operation of force modulation microscopy. The dynamic response of the can-tilever-bimorph drive amplitude is monitored while the cantilever deflection is held constant. The amplitude attenuation is related to the local surface stiffness.

Block copolymers are also cast or spin coated for evaluation by a range of techniques, and these are discussed later in this chapter (see Section 5.3.4.6). Chen and Thomas [113] used force modulation microscopy (FMM), a SPM technique that measures relative elasticity across a surface, to study the block copolymer morphology of roll cast and spin coated films. Three model samples were investigated unannealed poly(styrene-butadiene-styrene) triblock copolymer, fabricated from solution using roll casting, cut perpendicular to the oriented cylinders with a razor blade annealed and unannealed poly(styrene-h-methyl methacrylate diblock copolymer spin coated from solution and an ultrathin film of a rod-coil diblock copolymer cast from a dilute solution onto a carbon coated mica sheet. Triblock copolymers were strained in tension using a copper grid as support and...
