20.500.12556/RUL-167796 Effect of processing temperature on performance of screen-printed graphite electrodes Graphite thick films have been considered as an effective integrated working electrode in disposable electrochemical sensors for the on-site detection of pollutants in remote locations. The processing conditions of graphite thick films are not well documented, which hinders progress in their use. By combining profilometry, optical microscopy, X-ray powder diffraction, and Raman spectroscopy, we show that the structural development of graphite thick films strongly depends on the processing temperature. After thermal annealing of the screen-printed paste, the arrangement of the graphene layers improved and the organic components from the paste facilitated the fragmentation of the graphite grains. The resulting sheet resistance of the thick films decreases and contributes to a higher electron-transfer rate and thus to faster redox processes at the electrode surface. The elucidation of the relationship between processing and properties offers new opportunities to customise the properties of graphite thick films for a variety of applications requiring defect engineering. screen-printed electrodes graphite thick films cyclic voltammetry electrochemistry processing sitotisk elektrode debeli film true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-12 10:56:06 2025-03-12 10:56:07 2025-03-13 04:15:53 0000-00-00 00:00:00 2025 0 0 8 str. art. 130455 Vol. 337 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 54 1879-3312 10.1016/j.matchemphys.2025.130455 224407811 1-s2.0-S0254058425001014-main.pdf 1-s2.0-S0254058425001014-main.pdf 1 AE5D07437E830357566F39D309AAD641 ef6c1e11afd464e7577ff2768f7effb3c88ea84c4280ccccc6813ecc05695137 8c3bfdf0-ff27-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200570 https://www.sciencedirect.com/science/article/pii/S0254058425001014 0 3ec0566b-ff27-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200569 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
