Red various actions. The first stage was the deposition of polydopamine
Red numerous actions. The initial stage was the deposition of polydopamine coating on necessary quite a few measures. The initial stage was the deposition of aapolydopamine coating on the the paper, the initial and most conveniently noticeable impact of which was a change in the paper, the very first and most conveniently noticeable effect of which was a alter in the appearance look From white, the white, the paper turned brown, typical a common effect of in the paper.of your paper. Frompaper turned brown, which can be awhich is effect of applying a applying a polydopamine coating to different materials. to visual modifications, the deposition polydopamine coating to a variety of supplies. In additionIn addition to visual modifications, the of deposition of coating was confirmed by scanning electron microscopy photos and energy polydopamine polydopamine coating was confirmed by scanning electron microscopy dispersion spectroscopy analysis. A clear alter in the surface structure of cellulose fibers was visible, as well as the nitrogen signals inside the analysis on the chemical composition ofMaterials 2021, 14,14 ofthe surface, which confirmed the presence of polydopamine. Spot evaluation showed that the polydopamine coating was evenly deposited around the surface of the paper, and also the nitrogen content was between 9 and 21 at. . The exclusive properties of your polydopamine coating created it achievable to reduce silver ions from an aqueous salt solution of this element and to deposit metallic silver atoms around the surface. The content of silver atoms on the surface in the paper ranged from 12 to 60 at. . based on where the chemical composition was analyzed. Silver atoms Platensimycin Cancer successfully served as a catalyst for electroless metallization, as immediately after two.5 min of plating, a copper layer was visible on the surface with the paper, with a copper content material of approx. 32 at. . Increasing the metallization time improved the amount of deposited copper and, soon after 10 min, the copper content reached 88 at. . The deposition of the copper layer brought on a large reduce in the surface resistivity on the paper from 1013 to 107 (), which corresponds towards the order common for semiconductors. Such resistivity will let further present post-treatment of obtained electroless metallized paper. Furthermore, the obtained copper layer was characterized by higher adhesive strength and higher susceptibility to deformation, which will enable the usage of the metallized cellulose paper in electronics, which includes flexible electronic devices.Author Contributions: Conceptualization, K.M.; methodology, K.M., A.T. and R.M.; validation, K.M.; formal analysis, K.M.; investigation, K.M., A.T. and R.M.; sources, K.M.; information curation, K.M.; writing–original draft preparation, K.M.; writing–review and editing, K.M.; visualization, K.M.; supervision, K.M.
