A short random walk through polymer material behavior
Photographic film (or rather the base of a film) is made of transparent polymeric material. In this chapter we consider material properties of such film. Suppose a flat photographic film shown in Figure 16.1(a) is bent around a cylinder, as depicted in Figure 16.1(b), is held in this state for some time t w , and is then released. If the film were purely elastic then it will instantaneously recover its original flat shape.
