Subject imaging surface dynamics

Nagano and Nishimoto [11] used this technique to study the degradation due to weathering of styrene-butadiene vulcanisates. The degradation of these vulcanisates subjected to outdoor exposure in the Arizona desert for a year was studied. The dynamic viscoelasticity of sample sheets 2 mm thick and sliced films 0.2 mm thick was measured. SEM images of the surface and sheet cross-sections were also taken to observe microscopic changes in the samples.
