Observation Examples of Polymers
Observation of Polymer Films
A special film was observed after heating to 30°C, and to 50°C. In both cases, the topographic image is on the left and the phase image is on the right. No differences can be seen in the topographic images, however, differences are clearly apparent in the phase images. The visible changes indicate changes in viscoelasticity due to heating-induced physical changes in the film.
