Figure 9.22. Scanning force microscopy images of polyethylene films formed on a model planar chromium polymerization catalyst. The small white stripes are lamellar crystals. These form the well-known spherulite superstructure upon crystallization from the...

Fig. 6. Scanning force microscopy image of an ultrathin film of dendrimer 23 on HOPG. The cylindrical dendrimers are grouped in domains in which they are packed parallel to each other, with a periodicity of 5.0 ( 0.5) nm. Individual chain ends can be detected at grain boundaries. The nature of the unordered features is not yet understood...

Scanning force microscopy imaging provided further evidence for the successful conversion of the supramolecular polymers into covalent, conjugated polymers with retention of their hierarchical structure. First of all, SFM images obtained from any of the polymerizable macromonomers A-E looked virtually identical before and after polymerization. However, while the addition of a small amount of a deaggregating cosolvent such as hexafluoroisopropanol (HFIP) to the sample... 

Figure 17.7 Scanning force microscopy images taken in non-contact mode for neat C o and CuPc films as well as for three mixed films grown at 375 K. The total image size is 2 x 2 pm. The max. height is given as the difference between the lowest value (dark blue) and the highest value (white) in each of the images.

Monte Carlo simulations (Lai and Binder 1992). Figure 6.11 shows scanning force microscopy images of an end-grafted layer of a water-soluble polymer, dextran, which in water appears as a uniform layer, but, after the addition of a poor solvent, propanol, develops lateral structure (Frazier et al. 1997). As the grafting density is increased yet further the homogeneous, layer structure is expected once again to become stable.

Scanning force microscopy (SFM) is the only tool that allows one to image S-layer protein monolayers on solid supports at molecular resolution (Fig. lb and c) [22-25]. In particular, SFM in contact mode under water with loading forces in the range of <500 pN leads to an image resolution in the subnanometer range (0.5-1.0 nm).
