摘要： Medical diagnostic devices or components thereof are described that comprise a microstructured surface that comprises peak structures and adjacent valleys wherein the valleys have a maximum width ranging from 1 to 1000 microns and the peak structures. In some embodiments (e.g. for improved cleanability) the peak structures of the microstructured surface have a side wall angle of greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-comers elements. The microstmctured surface of the medical diagnostic device typically comes in contact with multiple patients during normal use of the device, such as a stethoscope diaphragm. The microstmctured surface exhibits better microorganism (e.g. bacteria) removal when cleaned and/or provides a reduction in microbial touch transfer. Also described are methods of making and methods of use.

摘要： A method of making a fluoropolymer coating composition is described comprising blending a latex comprising crystalline submicron fluoropolymer particles with a latex comprising amorphous fluoropolymer particles. The method further comprises coagulating and drying the blended latexes and dissolving the dried blended latexes in a fluorinated solvent. Also described is a fluoropolymer (e.g. coating) composition comprising crystalline submicron fluoropolymer particles dispersed in a solution of fluorinated solvent and amorphous fluoropolymer; the fluoropolymer composition after removal of the solvent; and a substrate comprising a coated surface of the fluoropolymer composition. In each of these embodiments, he amorphous fluoropolymer comprises at least 90 wt-% of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers.
