AbstractIn the study reported herein, silver-coated copper (Ag/Cu) powder was modified with alkanethiols featuring alkyl chains of different lengths, namely butyl, octyl, and dodecyl, to improve its thermal stability. The modification of the Ag/Cu powders with adsorbed alkanethiols was confirmed by scanning electron microscopy with energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. Each powder was combined with an epoxy resin to prepare an electrically conductive film. The results confirmed that the thermal stability of the films containing alkanethiol-modified Ag/Cu powders is superior to that of the film containing untreated Ag/Cu powder. The longer the alkyl group in the alkanethiol-modified Ag/Cu powder, the higher the initial resistance of the corresponding electrically conductive film and the lower the increase in resistance induced by heat treatment.

Inversion of the amide connectivity of an azobenzene dyad, which self-assembles into chiral toroids and nanotubes, improves the thermal stability of the assemblies, however it negatively affects supramolecular chirality.

Silver nanoparticles (AgNPs) were deposited onto surface-hydrolysed PET film by an electrostatic self-assembly technique, so as to fabricate multilayer nanocomposite films. The self-assembly process was monitored by ultraviolet-visible (UV-Vis) spectroscopy. The surface morphology and chemical composition of the multilayer nanocomposite films were characterised by Field Emission Scanning Electron Microscopy (FESEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The results showed that the AgNPs were uniformly dispersed on the PET film, in the metallic silver state. The thermal stability of the multilayer nanocomposite films was investigated by thermogravimetric analysis (TGA), and it was found that the presence of AgNPs on the surface of PET enhanced the thermal stability of the PET film. The antibacterial performance of the multilayer nanocomposite films was investigated by staphylococcus aureus to monitor the number of the bacterial cells. The results suggested that the PET films after assembled 10-bilayer PDDA/AgNPs multilayer films exhibited good antibacterial performance.
