        Visible-light-driven super-active Sn and GO single- and Sn/Cu Co-doped nanophotocatalysts for phenol degradation: Thin-film printability, thermal stability, and cytotoxicity assay

        Atasheh Soleimani-Gorgani,Jamal Al-Sabahi,Sepideh Akbaripoor Tafreshi Nejad,Maryam Heydari,Mohammed Al-Abri,Arash Namaeighasemi 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.120 No.-

        Sn- and graphene oxide (GO) single-doped and Sn/Cu co-doped titanium dioxide (TiO2) nanoparticleswere synthesized as printed-layer nano-photocatalysts for degradation of phenol under visible-light. The doped TiO2 nanoparticles (Sn-doped-TiO2, Cu/Sn-doped-TiO2, and GO-doped-TiO2) were synthesizedvia sol–gel method and calcinated at a temperature of 450 C. X-ray diffraction (XRD), UV–Visible DRSanalysis, Raman analyses, and Energy-dispersive X-ray spectroscopy (EDXS) were utilized to evaluatethe crystalline structure and photocatalytic activities of doped-TiO2 nanoparticles. Different screenprintingpastes were separately formulated with 26% w/w doped-TiO2 nanoparticles (Paste1-to-Paste3)for printing onto microscope glass slides. Photocatalytic printed film was sustainable filter for unusedsuspension of nanoparticles in wastewater. The printed pasts were sintered at varying temperatures(100–500 C), then three-layer printed nanoparticles sintered at 500 C examined for photocatalysis. Photocatalytic activity of single-layer-printed GO-doped-TiO2 nanoparticles was extraordinary (80%degradation of 10 ppm phenol solution). Hydroquinone, catechol, benzoquinone and acetic acid wereobserved to be produced at different concentrations over different time intervals as a result of phenoldegradation for single-layer-printed GO-doped-TiO2 nanoparticles sintered at 500 C. Bandgap of GOdoped-TiO2nanoparticles was 2 eV, meaningfully lower than anatase TiO2 (3.2 eV). The cytotoxicity assayapplied for normal and cancer cells demonstrated cytocompatibility besides photodegradability. Thisnovel process is a targeted, clean, cost-effective and on-demand approach, taking a big step towarddecontamination of the environmental pollution.

        Ink-jet Printing for the Fabrication of a Flexible Electrochromic Device Based on the Water-Soluble Viologen-Functionalized Dendrimer

        Yekefallah, Vahideh,Soleimani-Gorgani, Atasheh,Rouhani, Shohre,Najafi, Farhood The Korean Electrochemical Society 2021 Journal of electrochemical science and technology Vol.12 No.1

        This paper reports the preparation of an ink-jet printed flexible electrochromic device based on a water-soluble viologen-functionalized dendrimer. Polyamidoamine (PAMAM) dendrimers were modified with different concentrations of 1-1 bis(propylamine)-4,4'-bipyridylium dibromides to obtain solution-processable electrochromic materials (K1/2 and K1). FTIR, NMR, and elemental analyses are used to characterize synthesized viologens. Moreover, their electrochemical properties were investigated using cyclic voltammetry in an electrolyte solution consisting of 0.1 M HCl to find the optimum viologens. The low-cost ink-jet printer was used to print the prepared water-soluble electrochromic inks onto the ITO coated PET substrate to form desired transparent patterns. The electrolyte was applied on the printed electrochromic ink to make a sandwich with another ITO coated PET to prepare the electrochromic devices (ECD). By applying an electrical potential (0 to -2 V), the transparent ECD's color changed from colorless to blue. The color changes for the optimum ECD (K1), which had more viologen units on the dendrimer, was accompanied by an optical contrast of 47% and 311.5 ㎠C-1 coloration efficiency at 600 nm.

        Generation of Flexible Multifunctional Electronic Textile Displaying Appropriate Fastness Properties Utilizing Single-Stage Inkjet Printing onto Cotton Fabric Pre-treated with PVC

        Ali Goudarzi,Atasheh Soleimani‑Gorgani,Ozan Avinc 한국섬유공학회 2023 Fibers and polymers Vol.24 No.2

        Electrically conductive printed textiles are gaining increasing interest and demand worldwide. Cotton fabric's porosity andhigh surface roughness avoid electrically conductive printed patterns on the fabrics. This paper reports the in-situ solutiondeposition of silver free particles inkjet ink via an aqueous single-stage inkjet printing process, which improved electricalconductivity and fastness properties with a new approach. The cotton fabrics were pre-treated with different polyvinylchloride(PVC) solutions prepared in various solvents such as tetrahydrofuran (THF) and dimethylformamide (DMF) that differedin boiling temperature. Afterward, PVC-pre-treated fabrics were printed through the HP Deskjet inkjet printer. The resultsshowed that the PVC-pre-treatment of cotton fabrics significantly improved the electrical conductivity (< 2 Ω/□), antibacterialactivity, thermal management, droplets repellency, adhesion, abrasion, and washing fastness properties, as well as flexibilityproperties. The solvent type in PVC solutions affects the physical properties of the pre-treated cotton fabric. The comparisonin rheological behavior of PVC solutions in DMF and THF at different temperatures displayed the significant difference inviscosity at gel-point for THF and DMF solution. THF solution with higher viscosity cannot diffuse more into porositiesof cotton fabric than the DMF solution, which affects the silver nanoparticles' average crystal size and the final electricalconductivity of the printed fabric. It is the first time using an economical polymer layer on cotton fabrics to provide robustelectronic printed patterns by single-stage inkjet printing. The results confirm that the flexible electronic printed fabric canbe used as a multifunctional electronic textile.
