Only C, N, and O elements are present in the full XPS spectra (Fig. 3a) of degummed and pretreated silk, while Ce3d signals are present in the SF/CeO 2 spectrum and S peaks are evident in the...

Feb 1, 2024 · Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) primarily underscored transformations in SF's nitrogenous components. Specifically, treatment produced a boost in C-NH2, particularly pronounced in the 45 o-treated samples, suggesting changes were more superficial than alterations to the secondary structure.

Oct 1, 2020 · The chemical structure of modified TP and treated silk fabric were tested via FT-IR and XPS. The thermochromic process of samples were exhibited via checking the color parameters in the heating-cooling cycle. The durability of treated silk fabric was tested by washing fastness and rubbing fastness.

This study presents the first example of the production of soy and silk fibroin protein composite nanofibers in various ratios via combining ultrasonic technology with air-spray spinning.

The surface morphology and topography, structure, and wettability properties of bare silk fabric and TiO2-coated silk fabrics thus prepared are evaluated using scanning electron microscopy (SEM), field-emission scanning electron microscopy (FESEM), scanning probe microscope (SPM), X-ray diffraction (XRD), static water contact angles (WCAs), and ...

The modified silk fabrics (TP-SF/Fe) were characterized via Fourier-transform infrared (FTIR), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), and X-ray photoelectron ...

May 15, 2013 · Micro-destructive surface techniques, such as XPS and TOF-SIMS, led to the acquisition of detailed information on natural dyes, both in the reference silk fabric with commercial dyes and in silk textiles dyed with natural plant extracts by traditional process.

Jul 29, 2024 · Through atomic-scale surface analysis, the physical distribution of silk in the metal-oxide films was traced, revealing an adaptive adsorption mechanism. Through this study, we proposed a...

Silk fabrics were treated with 02, N2, and H. plasmas for deep dyeing and good color fastness to rubbing. C.I. (Color Index) Reactive Black 5 was used as a dye, and color deepness was evaluated by total K/S. All plasma-treated silk fabrics showed weight loss, especially by …

Feb 25, 2025 · X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared (FTIR), and X-ray Diffraction (XRD) analyses showed that Ag NPs bind to silk fibroin via coordination with –NH 2 groups, inhibiting β-sheet formation and promoting protein crystallization.
