Abstract
U ovom radu je provedena usporedba dviju metoda obrade inkjet tiskane nanosrebrne tinte na staklenoj podlozi. U peći za žarenje provedena je klasična toplinska obrada tankih filmova, a pomoću sustava za generiranje intenzivne pulsirajuće svjetlosti fototermalna obrada. Preliminarnim ispitivanjima definirane su granične vrijednosti ulaznih parametara potrebnih za dizajniranje eksperimenta. Korištenjem programa Design-Expert predložen je minimalni broj eksperimenata za određivanje optimalnih uvjeta temperature i vremena obrade za toplinski proces, odnosno energije i broja bljeskova za fototermalni proces obrade. Također su određeni parametari s ključnim utjecajem na kvalitetu i električnu vodljivost nanosrebrnog tankog filma inkjet ispisanog na staklenoj podlozi. Kako bi se utvrdila debljina sloja ispisanog materijala prije i nakon obrade te njegova homogenost korišten je mikroskop atomskih sila. Nakon provedenih eksperimenta optimizirani su parametri te je iz rezultata vidljivo da najbolju poželjnost modela s rezultatima daje obrada pomoću intenzivne pulsirajuće svjetlosti (IPL) pri uvjetima maksimalne energije od 2500 J i jednog bljeska. Pri obradi IPL-om sa pločicama podignutim od podloge dobije se idealna poželjnost od 100% dok se pri obradi bez izolacije od podloge dobije poželjnost od 90,1%. Najbolja poželjnost toplinske metode i modela, od 88,5%, očituje se pri minimalnoj temperaturi od 175 °C i vremenu zadržavanja od 79,61 minuta.
Abstract (english)
In this study, a comparison of two processing methods of inkjet printed nanosilver ink on a glass substrate was performed. Thin films were subjected to the traditional method of heat treatment in the annealing furnace and a technology for creating intense pulsed light (IPL) was used for photothermal treatment. The Design-Expert program was used to propose the minimum number of experiments to establish the optimal temperature and processing time conditions for the thermal process, and energy and number of flashes for the photothermal process. The parameters that impact the quality and electrical conductivity of an inkjet-printed nanosilver thin film on a glass substrate are also found. An atomic force microscope was used to determine the thickness of the printed material layer before and after processing and its homogeneity. After the experiments, the parameters were optimized, and the results show that the best fit between the model and the experimental results is when IPL is used to process it with 2500 J and one flash. The best result, with 100% fit, is obtained by IPL with 2 mm raised sample, while the best result by sample not raised from base surface is 90.1%. The best desirability of the thermal method and model is 88.5%, which is manifested at a minimum temperature of 175 °C and a duration of 79.61 minutes.
