Polymer Analysis
Failure modes of polymeric materials include fracture, cracking, delamination, corrosion, blistering, coating detachment, discoloration, and wear. Common analytical techniques encompass compositional analysis, thermal analysis, pyrolysis‑gas chromatography‑mass spectrometry (Py‑GC‑MS), fracture surface analysis, and physical property characterization, utilizing the following instruments: Fourier‑transform infrared spectroscopy (FTIR), micro‑confocal Raman spectroscopy (Raman), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray fluorescence spectroscopy (XRF), gas chromatography–mass spectrometry (GC‑MS), pyrolysis‑GC‑MS, nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), time‑of‑flight secondary ion mass spectrometry (TOF‑SIMS), gel permeation chromatography (GPC), melt flow index (MFI) testing, Shore hardness testing, and others.
