“…[29][30][31] Zinc oxide nanoparticles have been used in polyfluorene composites for lightemitting field effect transistors, 32 whilst Q-ZnO has been applied as a component in a hybrid OFET bilayer device fabricated with P3HT as the organic film. 33 Blends of P3HT and CdSe have been studied in OFETs 34 and also in organic photovoltaics devices. 35 However, the mechanism of charge transport in these composites is not well understood.…”

The addition of oleylamine coated Cu2ZnSnS4 (CZTS) nanoparticles to solutions of an organic semiconductor used to fabricate organic field-effect transistors (OFETs) has been investigated. The oligothiophene-based small molecule 5T-TTF and the polymer poly(3-hexylthiophene) (P3HT) were each applied in the transistors with various concentrations of CZTS (5-20%). Atomic force microscopy (AFM) was applied to characterise the surface morphology of the OFETs. The use of 5 and 10 wt% of the CZTS nanoparticles in 5T-TTF and P3HT solutions, respectively, appears to be a simple and effective way of improving OFET performance

“…Colloidal dispersions containing NPs having mean core diameter below 10 nm are obtained . ZnONPs were synthesized via an electrochemical‐thermal route as described in detail in our recent work . Briefly, nanogels of zinc hydroxides–carbonates‐mixed species are first electrosynthesized under mild galvanostatic conditions employing a zinc sheet as sacrificial anode in the presence of poly(sodium‐4‐styrenesulfonate) as NP stabilizer in a sodium bicarbonate aqueous solution.…”

“…In this paper, we report on the impregnation of various textiles with copper and zinc oxide nanomaterials in order to confer them antimicrobial properties. CuNPs and ZnONPs have been electrosynthesized and characterized following previous protocols; here, they are specifically investigated in the textile context, and a detailed surface spectroscopic investigation is used to fully characterize the modification of the textile products upon NPs impregnation. CuNPs have been prepared by means of sacrificial anode technique in the presence of tetraoctylammonium chloride as stabilizing agent and are characterized by nanometer‐sized diameter and narrow size dispersion.…”

Colloids of antimicrobial metal and metal oxide nanoparticles (NPs) were electrochemically prepared and then used as surface modifiers for industrial batches of textiles. Different surface loadings could be easily deposited on the surface of the products of interest in order to inhibit the growth of microbes such as bacteria. Surface chemical characterization was performed using X-ray Photoelectron Spectroscopy technique to quantitatively assess the materials' surface chemical composition. Moreover, the NP chemical speciation was evaluated and correlated to the electrosynthesis characteristics, processing conditions, and textiles storage time. Atomic absorption spectroscopy was employed to quantify the metal ions release in a proper contact solution in order to correlate the surface and bulk availability of NPs with the antimicrobial efficacy. Promising spectroscopic results strongly support future real-life applications in different fields

The optical properties of nanocomposite layers prepared by incorporation of tributylphosphine oxide (TBPO)-capped CdSe nanocrystals (NCs) in a P3HT polymer matrix are studied using different nanocrystal concentrations. Reflection spectra analyzed through Kim oscillator model lead to the determination of optical constants such as refractive index n, extinction coefficient k, dielectric permittivity e and absorption coefficient a.Using the common Cauchy, Drude-Lorentz, Tauc and single-effective-oscillator theoretical models, we have determined the values of static refractive index n s and permittivity e s , plasma frequency x p , carrier density N, optical band gap E g and oscillator and dispersion energies E 0 and E d , respectively. It is found that TBPO-capped CdSe NCs concentration affects the optoelectronic parameters of the nanocomposite thin films. Moreover, the disorder of this hybrid system is also studied by the determination of Urbach energy, which increases with TBPO-capped CdSe concentration.
