Abstract:V diplomskem delu raziskujemo delovanje in odziv elektrokromnih trakov, sestavljenih na principu konfiguracije ''inverznega sendviča''. Zanima nas barvni odziv sestavljenih naprav, njihova stabilnost, potreba po velikosti vložene električne napetosti, reverzibilnost ter življenjska doba le-teh. Elektrokromni trak je sestavljen iz dveh elektrod, kjer je na eni elektrodi nanesena plast kovinskega oksida, na drugi pa plast grafita. Ločuje ju izolator, ki preprečuje kratek stik, povezuje pa ju elektrolit, ki zagotavlja prenos naboja iz ene elektrode na drugo. Celoten trak povezuje nosilec elektrolita iz vpojnega papirja, ter prosojna plastična skrčka, ki omogoča optimalno zatesnjenost traku. Preučujemo različne vrste kovinskih oksidov, ki jih bomo na jeklo nanašali na enostaven način s pomočjo tankoplastnih tehnik ''Doctor Blade'' in metode ''zniževanja gladine'' (angl. Inverse dipping). Prav tako raziskujemo različne vrste elektrolitov, ki bodo uporabljeni v sestavi elektrokromnega traku in bodo omogočali dovolj hiter odziv, hkrati pa ne bodo imeli kvarnega vpliva na stabilnost in delovanje naprave. S pomočjo različnih karakterizacijskih metod, kot so kronoamperometrija, UV-Vis reflektančna spektroskopija, elektrokemična impedančna spektroskopija, SEM (angl. Scanning electron microscope) in EDS (angl. Energy-dispersive X-ray spectroscopy) smo posneli različne tipe meritev in na osnovi teh določili učinkovitost sestavljenih elektrokromnih trakov.

Title:Optimization of electrochromic tape using different metal oxides
Abstract:In this thesis work we are investigating the working nature and response of electrochromic tapes, composed on the principle of "inverse sandwich" configuration. We are interested in the color response, it's stability, the need for the applied electrical voltage, reversibilityand their life span. The electrochromic tape consists of two electrodes, where a layer of metal oxide is applied to one electrode and a layer of graphite is applied to the other. The two are separated by an insulator, which prevents short circuits, and connected by an electrolyte, which ensures charge transfer from one electrode to the other. The entire tape is connected by an electrolyte holder made of absorbent paper and a transparent plastic shrink, which enables optimal sealing of the tape. We study different types of metal oxides, which will be applied to steel in a simple way with the help of thin-layer techniques such as "Doctor Blade" and the "Inverse dipping" method. We are also investigating diffrent types of electrolytes that will be used in the composition of the electrochromic tape and will allow for a sufficiently fast response, while not having detrimental effects on the stability and operation of the device. Using various characterization methods, such as chronoamperometry, reflectance, electrochemical impedance spectroscopy, SEM (Scanning electron microscope) and EDS (Energy-dispersive X-ray spectroscopy), we performed diffrent types of measurments and based on these we determined the effectiveness of the composited electrochromic tapes.
