One common example is indeed phase imaging, as described above, to discern phase segregation in block copolymer systems. ” This of course adds to the confusion. Phase segregation refers to the tendency of certain substances to separate from one another, such as oil and water, provided thermal motion and time. Thus, one obtains domains rich in one type of molecule or another. Block copolymers are long-chain molecules containing long “blocks” of one homopolymer or another. That is, each long block contains repeated “mers” of the same chemistry, one polymer.

Thus, a very brief and purely vertical touch of tip to surface, with the tip remaining off the surface most of the time while scanning the surface, is key to avoiding or minimizing many of the above problems. The general term for such an imaging scheme is intermittent contact. There is more than one way to implement intermittent contact, different modes of operation. 2, we showed images acquired with high-speed force-curve mapping [22], which uses the Z scanner to approach and touch tip to surface then retract, as few as one touch per pixel in the image.
