摘要：

The status of soft X-ray spectromicroscopy (near edge X-ray absorption, or NEXAFS, microscopy) is summarized, with particular emphasis on recent collaborative studies carried out by the author's group at the scanning transmission X-ray microscopy (STXM) and the photoelectron emission microscopy (PEEM) instruments at the Advanced Light Source. Results described include: characterization of phase segregation and filler particles in polyurethanes; effects of confinement on polymer self-organization; characterization of chemically structured polyurea capsule walls; and preferential interactions of proteins with chemically heterogeneous polymer surfaces. The latter is part of a systematic study of the biocompatibility of polymers used in blood contact applications.
