X-ray photoelectron spectroscopy analysis

X-ray Photoelectron Spectroscopy analysis of the samples was performed with a Surface Science Instruments spectrometer (SSI 100) with a resolution (FWHM Au 4f7/2) of 1.0 eV. The X-ray beam was a monochromatised AlKa radiation (1486.6 eV). A charge neutraliser (flood gun) was adjusted at an energy of 6 eV. As the Cls spectra of these compounds were very complex, the binding energies were referenced to the binding energy of Ols, considered experimentally to be at 531.8 eV [8).

Aminated PS-based latices were prepared by dispersion polymerisation and were characterised. Mixtures of Boc-p-aminostyrene and styrene monomers at various compositions were copolymerised under dispersion conditions in 2-propanol/water 3 1 by volume in the presence of AIBN as free radical initiator at 75C. Copolymer microspheres with uniform size distributions and average diameters between 0.9 and 1.8 micrometres were obtained. Aminated microspheres were obtained by the simple removal of the Boc protective group under acidic conditions, followed by neutralisation, thus leading to p-aminostyrene/styrene copolymers. These chemical treatments, when carried ont nnder mild conditions (room temp, and dilute acid and basic solutions), were efficient without causing any major alteration of the microsphere morphology. X-ray photoelectron spectroscopy analysis of the prepared microspheres showed an increase of amino groups with increase of the Boc-p-aminostyrene in the copolymer feed up to 10 mol %. 26 refs.

Significant progress in this area has been made. It has been shown recently that the polarity of the casting substrate may provide an avenue for surface wetting without surface treatment. The casting of silicone-based formulations from polar mold materials results in a surface rich character. For example, a copolymer based on a fiuorinated silicone and the hydrophilic monomer, DMA was cast against the hydrophilic mold resin Barex (copolymer of acrylonitrile and styrene). X-ray photoelectron spectroscopy analysis of the surface showed a threefold increase in surface nitrogen concentration as compared with the same formulation cast from a hydrophobic polypropylene resin. The Barex cast material resulted in...

X-ray photoelectron spectroscopy analysis allows for identification of various elements as well as differentiation of various chemical oxidation states. In order to accomplish these tasks, the energy resolution must be sufficiently high so that peaks from different chemical oxidation states can be deconvoluted. Eurthermore, the resolution should remain relatively constant for all elemental transitions, i.e., the absolute resolution, AE, (defined by the fwhm) must remain the same. If the linewidths are to be matched by the absolute resolution at the maximum photon energies...
