“…C1s was adjusted using 5 curves with FWHM (Full Width at Half Maximum) = 1.0 ± 0.1 eV; N1s was adjusted with 4 curves with FWHM = 1.2 ± 0.1 eV and O1s was adjusted with 3 Gaussian curves with FWHM = 1.4 ± 0.1 eV . Figures a–c show plots with the participation percentage and the maximum binding energy (BE) of each Gaussian curve associated with specific chemical states . The states were assigned considering all possible chemical bonds of each element, C = 4, N = 3 and O = 2, with the surrounding atoms.…”

Polypyrrole synthesized and doped with iodine by plasma was used to cover stainless steel stents in order to reduce the contact of blood with the metallic surfaces in the circulatory system. This study was directed to identify the chemical states in the first 95 nm depth of the polymeric coatings using XPS with Ar erosion. The results showed that the coatings have percentages of chemical states of pyrrole that did and others that did not participate in the polymerization. Oxidation was found along the depth profile of the coatings and not only on the surface, which suggests atmospheric oxidation and the formation of oxygen bridges due to the sensitization step applied previously to the polymerization, that could improve the adhesion with the metallic surfaces. The interaction of iodine with the polymer was also identified in the polymers. In general, the coatings have functional groups that are typically found in compatible polypyrroles.

“…Figure shows a SEM micrograph of PPFu synthesized at 100 W. The particles are spherical, smooth and agglomerate randomly. The PPFu particles have size as a function of the synthesis power . The particle diameter is between 95 and 3500 nm, see the Table in Figure , which also shows the total mass obtained in each synthesis, the size interval and mean particle diameter (MD).…”

The electromagnetic absorption and electronic activation energy of plasma polyfuran particles synthesized by plasma are studied in this work. The particles were synthesized in configurations resulting from crosslinked unions of Furan molecules. Aliphatic CH groups were identified in the particles, which suggest some fragmentation during the synthesis. Conjugated CC groups were also identified which promoted that the particles absorb electromagnetic energy in four regions with different intensities, one in the UV and three in the visible region. The wavelength intervals in these regions were: 250–380, 380–510, 510–660 and 660–850 nm; and the respective activation energy in each region was in the intervals: 5.82–8.58, 4.19–6.74, 2.14–3.86, 0.16–1.08 eV. The electromagnetic absorption was influenced by the particle diameter, increasing with the mean diameter.

Polymer electrode materials (PEMs) have become a hot research topic for lithium-ion batteries (LIBs) owing to their high energy density, tunable structure, and flexibility. They are regarded as a category of promising alternatives to conventional inorganic materials because of their abundant and green resources. Currently, conducting polymers, carbonyl polymers, radical polymers, sulfide polymers, and imine polymers as five kinds of PEMs are studied extensively. This review introduces the latest research progress of PEMs for LIBs from the perspectives of molecular structure, redox mechanism, and electrochemical performance. The synthesis mechanisms and methods are outlined to guide the future design of PEMs. However, the practical application of PEMs is limited by their insufficient conductivity, structural instability, and high solubility. Aiming at these obstacles, reasonable optimization strategies are discussed, including the modification of molecular structure, the control of micromorphology, and the composite of carbon materials. Finally, the development trends and prospects of PEMs are put forward.
