AN 9589 - Microscopic Structural Studies on Polymer Surfaces using FT-Raman and FT-IR
Description:
FT-Raman microscopy can measure spectra from a range of thermoplastics. This note is an in depth study of the use of FT-Raman to provide depth profiling information of samples of UV treated polyvinyl chloride(PVC). FT-Raman proved very sensitive to the formation of carbon double bonds in the structure due to the formation of polyene breakdown products which occur in the weathering process. Analysis of Raman bands at 1493 cm-1(-C=C-) and at 1126 cm-1(=C-C=) in a linear microscope map, suggest the depth to which the UV radiation penetrates.
Environment:
- FT-Raman
- FT-IR
