Chemical Characterization of Polymeric Films, Blends, and Self-Assembled Monomers

Infrared (IR) spectroscopy is highly specific for identifying chemical composition, because each individual compound has a characteristic IR spectrum that serves as a “fingerprint” to uniquely identify the compound. This makes IR spectroscopy the most widely used technique for characterizing surface chemistry, from lubricant layers to deposited thin films down to molecular monolayers. Experimental design depends on the surface composition and morphology, and must include specific hardware including sampling accessories. Instrument settings need to be optimized to reduce spectral noise.

The latest advances in the instrumentation and applications of vibrational spectroscopy for the chemical analysis of surfaces will be reviewed in this presentation with a thorough discussion of the following topics:

Surface characterization techniques: ATR (attenuated total reflection), including GATR (grazing angle germanium ATR): External (specular) reflection, including IRRAS (infrared reflection and absorption spectroscopy); and DRIFTS (Diffuse Reflection Infrared Fourier Transform Spectroscopy)

Characterization of thin films and molecular monolayers deposited onto metallic, semiconductor, and dielectric substrates

Heterogeneous gas-solid catalysis studies of gases interacting with catalytic surfaces
