For this purpose, shear thickening fluids based on polypropylene glycols PPG400 and PPG1000 and Aerosil\u00ae200 were developed. The shear thickening behavior of obtained fluids was confirmed by using a parallel-plate rheometer. Next, thermogravimetric (TG) analyses were used to characterized thermal stability and weight loss of the STFs at a constant temperature. Finally, the thermal treatment of the STFs obtained was provided using the apparatus developed for this purpose. The received STFs exhibited a very high maximum viscosity up to 15 kPa. The rheology of the STFs measured after thermal treatment indicated that the proposed method allowed the development of STFs with a very high maximum viscosity. The maximum viscosity of the STFs increased twofold when thermal treatment of the STFs at elevated temperature for 210 min was performed. TG confirmed the convergence of the weight loss in the apparatus. Our results show that controlling the thermal treatment of STFs allows STFs to be obtained with high viscosity and a dilatation jump of the STFs by degradation of the liquid matrix.<\/jats:p>","DOI":"10.3390\/ma15175818","type":"journal-article","created":{"date-parts":[[2022,8,24]],"date-time":"2022-08-24T02:55:34Z","timestamp":1661309734000},"page":"5818","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Unexpected Method of High-Viscosity Shear Thickening Fluids Based on Polypropylene Glycols Development via Thermal Treatment"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6257-4112","authenticated-orcid":false,"given":"Mariusz","family":"Tryznowski","sequence":"first","affiliation":[{"name":"Faculty of Mechanical and Industrial Engineering, Warsaw University of Technology, Narbutta 85, 02-524 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7594-1145","authenticated-orcid":false,"given":"Tomasz","family":"Go\u0142ofit","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3, 00-664 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selim","family":"G\u00fcrgen","sequence":"additional","affiliation":[{"name":"Department of Aeronautical Engineering, Eski\u015fehir Osmangazi University, Eski\u015fehir 26040, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrycja","family":"Kr\u0119cisz","sequence":"additional","affiliation":[{"name":"Faculty of Material Engineering, Warsaw University of Technology, Wo\u0142oska 141, 02-507 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4714-3466","authenticated-orcid":false,"given":"Marcin","family":"Chmielewski","sequence":"additional","affiliation":[{"name":"Institute of Microelectronics and Photonics, \u0141ukasiewicz Research Network, Lotnik\u00f3w 32\/46, 02-668 Warsaw, Poland"},{"name":"National Centre for Nuclear Research, Materials Research Lab, \u015awierk, 05-400 Otwock, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"106954","DOI":"10.1016\/j.tws.2020.106954","article-title":"Rheometry of Novel Shear Thickening Fluid and Its Application for Improving the Impact Energy Absorption of P-Aramid Fabric","volume":"155","author":"Ghosh","year":"2020","journal-title":"Thin-Walled Struct."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"15312","DOI":"10.1021\/jp905949g","article-title":"Thermodynamic Properties of Hyperbranched Polymer, Boltorn U3000, Using Inverse Gas Chromatography","volume":"113","year":"2009","journal-title":"J.
