20.500.12556/RUL-168721 Synthesis of a new amino/phosphate-modified TiO2/rGO hybrid nanocomposite for sustainable textile functionalization Nanocomposites of titanium dioxide (TiO$_2$) and reduced graphene oxide (rGO) have been considered in recent years as effective photocatalysts for the development of textiles with functional protective properties. This work presents a simple strategy for synthesis of a new type of amino/phosphate-functionalized TiO$_2$/rGO hybrid nanocomposites on the surface of cotton fabric through an effective sol–gel and sol–gel/hydrothermal route. For this purpose, (trihydroxysilyl)propyl methylphosphonate (TPMP) and (3-aminopropyl)triethoxysilane (APTES) were used to enhance the interfacial interaction among TiO$_2$, rGO, and textiles, while also providing an antimicrobial bio-barrier and thermal stability in addition to the photocatalytic activity of TiO$_2$/rGO. The analysis of the developed nanocomposites using field emission scanning electron microscopy (FE-SEM), energy-dispersive Xray (EDS), X-ray diffraction microscopy (XRD) and X-ray photoelectron spectroscopy (XPS) confirmed the presence of all crucial active compounds in the composites and revealed the amorphous phase of TiO$_2$ irrespective of the application route. Fourier transform infrared spectroscopy (FTIR) confirmed the presence of TPMP and APTES functional groups and the formation of Si-O-Ti and Si-O-Si bonds, indicating the successful synthesis of the amino/phosphate-functionalized TiO$_2$/rGO nanocomposite on the surface of the cotton fabric. Compared with the sol–gel/hydrothermal route, the sol–gel route proved to be more efficient and assured the tailoring of the amino/phosphate/TiO$_2$/rGO nanocomposite with superior performance in UV protection, antimicrobial activity against bacteria E. coli and S. aureus and photocatalytic self-cleaning activity in the discolouration of Rhodamine B dye, as well as improved thermo-oxidative stability as determined through thermogravimetric analysis (TGA). cotton fabric titanium dioxide (TiO2) reduced graphene oxide (rGO) hybrid nanocomposite sol–gel sol–gel/hydrothermal functional textile bombažna tkanina titanov dioksid (TiO2) reduciran grafen oksid (rGO) hibridni nanocompoziti sol-gel sol-gel/hidrotermalen funkcionalne tekstilije true false true Angleški jezik Slovenski jezik Članek v reviji 2025-04-18 14:26:40 2025-04-18 14:26:41 2026-01-20 14:40:21 0000-00-00 00:00:00 2025 0 0 19 str. iss. 3, [article no.] 116555 Vol. 13 Jun. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-06-01 677 2213-3437 10.1016/j.jece.2025.116555 232996867 1-s2.0-S2213343725012515-main.pdf 1-s2.0-S2213343725012515-main.pdf 1 487972D91EF7B1777616AB5DAA0A7B48 cbd09ef45732350311fee001226515025ed202127299a7db689b2e682d430bef 989d14b1-1c4f-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209611 https://www.sciencedirect.com/science/article/pii/S2213343725012515 1 3b9a9e5a-f605-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225752 Zdravstvena fakulteta Naravoslovnotehniška fakulteta Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
