Nanoparticles of silica were dispersed in 50-50 ethylene glycol (EG)\u2013water and 50-50 propylene glycol (PG)\u2013water mixtures, and the zeta potential was studied as a function of acid, base, and surfactant concentrations. The addition of HCl had a limited effect on the zeta potential. The addition of NaOH in excess of 10\u22125 M induced a zeta potential of about \u221280 mV in 50% EG, but in 50% PG the effect of NaOH was less significant. The addition of CTMABr in excess of 10\u22123 M induced a zeta potential of about +100 mV in 50% EG and in 50% PG. The addition of SDS in excess of 10\u22123 M induced a zeta potential of about \u221280 mV in 50% EG and in 50% PG. Long-chained analogs of SDS were even more efficient than SDS, but their application is limited by their low solubility in aqueous glycols.<\/jats:p>","DOI":"10.3390\/molecules28031335","type":"journal-article","created":{"date-parts":[[2023,1,31]],"date-time":"2023-01-31T01:35:45Z","timestamp":1675128945000},"page":"1335","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Zeta Potential of Nanosilica in 50% Aqueous Ethylene Glycol and in 50% Aqueous Propylene Glycol"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9698-7190","authenticated-orcid":false,"given":"Marek","family":"Kosmulski","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Lublin University of Technology, Nadbystrzycka 38, 20618 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"Kalbarczyk","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Lublin University of Technology, Nadbystrzycka 38, 20618 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118282","DOI":"10.1016\/j.applthermaleng.2022.118282","article-title":"Misconceptions in the measurements of zeta potentials in ethylene glycol-based heat transfer fluids","volume":"209","author":"Kosmulski","year":"2022","journal-title":"Appl.
