20.500.12556/RUL-137098 In-depth rheological characterization of tungsten sol-gel inks for inkjet printing The inkjet printing of the functional materials prepared by the sol-gel route is gaining the attention for the production of the variety of the applications not limited to the printed boards, displays, smart labels, smart packaging, sensors and solar cells. However, due to the gelation process associated with the changes from Newtonian to non-Newtonian fluid the inkjet printing of the sol-gel inks is extremely complex. In this study we reveal in-depth rheological characterization of the WO$_3$ sols in which we simulate the conditions of the inkjet printing process at different temperature of the cartridge (20–60 °C) by analyzing the structural and rheological changes taking place during the gelation of the tungsten oxide (WO$_3$) ink. The results provide the information on the stability of the sol and a better insight on the effects of the temperature on the gelation time. Moreover, the information on the temperature and the time window at which the inkjet printing of the sol-gel inks could be performed without clogging were obtained. The WO$_3$ ink was stable in a beaker and exhibited Newtonian flow behavior at room temperature over 3 weeks, while the gelation time decreased exponentially with increasing temperature down to 0.55 h at 60 °C. rheology inkjet printing tungsten oxide sol-gel materiali sol-gel newtonska tekočina aplikacije true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-01 11:07:14 2022-06-01 11:07:14 2022-09-15 04:14:39 0000-00-00 00:00:00 2022 0 0 15 str. iss. 2, art. 112 Vol. 12 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1/.2 2079-6412 10.3390/coatings12020112 96639491 coatings-12-00112-v2.pdf coatings-12-00112-v2.pdf 1 2FB5F246F1BA5762AD0B33E233D07D8E a39bd6111e60ab0d76f0986a6c1d6c97708ab66073123ac224e46062a89fe284 6f00577a-e18a-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156952 https://www.mdpi.com/2079-6412/12/2/112 1 15313f76-e18a-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156950 Fakulteta za elektrotehniko Fakulteta za kemijo in kemijsko tehnologijo Fakulteta za strojništvo 0 0 0
