The poly(L-lysine) formed a-helical rods in the multilayers that are aligned along the scratching direction of the substrate. He applied attenuated total reflection-Fourier transform spectroscopy (ATR-FTIR) using polarized light for the determination of the orientation within the films. 

The characterization of surface structure for miscible blends is a more formidable task, requiring techniques that are sensitive to the composition of the blend within several nanometers of the surface. X-ray photoelectron spectroscopy (xps) provided the first direct and quantitative evaluation of surface composition and surface composition gradients for miscible polymer blends of poly(vinyl methyl ether) (PVME) and polystyrene (PS) (22,23). Since that time, the situation has changed dramatically with the advance of theory and the application of exciting new experimental techniques to this problem. In addition to xps and pendant drop tensiometry (22,23), forward recoil spectroscopy (28), neutron (29) and x-ray reflectivity (30), secondary ion mass spectroscopy (either dynamic or time-of-flight-static) (31,32), and attenuated total reflectance Fourier transform infrared spectroscopy (33-35), have been applied successfully to study surface segregation. The advent of these new tools has enabled a multitechnique experimental approach toward careful examination of the validity of current surface segregation theories (36-39).

Hsu and Marshall identified dyes in solid poly(methylmethylacrylate) by laser desorption Fourier Transform Ion Cyclotron Resonance Mass Spectrometry. Accurate mass measurements identified several red and orange dyes in untreated poly(methmethacrylate) at an order of magnitude lower (0.1%) than obtained by infrared attenuated total reflectance spectroscopy (1 - 2%).
