Preparation and Properties of Water-Resistant Antibacterial Curcumin/Silver Composite Nanofiber
Meiping Chen,Chao Ma,Change Zhou,Zhiguang Li,Rong Li 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11
The water-resistant antibacterial PVA nanofibers containing curcumin (Cur) and silver nanoparticles (AgNPs) were prepared by electrospinning, and the AgNps were prepared by in situ reduction in the spinning solution. The prepared PVA nanofibers were measured by scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectrophotometer (FT-IR). The breathable, hygroscopic, antibacterial, anti-inflammatory, and antioxidants functions of the prepared nanofibers were evaluated. The results indicated that the prepared nanofiber membrane has high swelling rate, moisture permeability, good mechanical properties, good biocompatibility, anti-inflammatory, antioxidant, and bacteriostatic activities with no cytotoxicity. Curcumin and AgNPs in the prepared nanofiber have effect on antibacterial activity and wound healing. The functionalized silver nanoparticles developed have effective activities against both Gram-negative bacteria and Gram-positive bacteria. In short, Cur/AgNPs composite nanofibers can be used as a potential medical dressing with antibacterial, anti-inflammatory, and antioxidant properties.

Fabrication of Stable Fluorine-Free Hydrophobic Cotton Fabrics with Prominent Antibacterial Property
Fengyi Qian,Meiping Chen,Zhiguang Li,Change Zhou,Rong Li,Xuehong Ren 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11
Multifunctional cotton fabrics with antibacterial property and hydrophobicity were prepared using surface modification. Cotton fabrics were treated with the coating solution containing N-halamine compound poly[5,5-dimethyl-3-(3’-triethoxysilylpropyl) hydantoin] (PSPH) and TiO2 nanoparticles, followed by treated with polydimethylsiloxane (PDMS) to reduce the surface energy of cotton fabrics. The prepared cotton fabrics were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared (FT-IR) spectra, X-ray photoelectron spectroscopy (XPS), and X-ray diffractometry (XRD). After chlorination, the prepared cotton fabrics exhibited excellent hydrophobicity with contact angle of 143°. The antibacterial results demonstrated that the prepared cotton fabrics had excellent antibacterial activity and could completely inactivate 4.54 cfu/sample of S.aureus and 4.92 cfu/sample of E. coli O157:H7 within 30 min of contact. The treated cotton fabrics also possessed robust stability under washing, UV light irradiation, and abrasion. Moreover, the breaking strength and air permeability of cotton fabric could maintain to the required values for practical application after treatment.

Multifunctional polysiloxane was synthesized by introducing N-halamine compound precursor and stearyl methacrylateinto polyhydromethylsiloxane, and characterized by Fourier transform infrared (FT-IR) and 1H nuclear magnetic resonance(NMR). Cotton fabrics with antibacterial and hydrophobic properties were prepared via a simple one-pot method with thesynthesized polysiloxane and rutile TiO2nanoparticles. The prepared cotton fabrics was characterized by scanning electronmicroscopy (SEM), FT-IR, X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The results demonstratedthat prepared cotton fabrics could inactivate 3.9 × 106cfu/sample of S. aureus and 4.8 × 106cfu/sample of E. coli O157:H7within 30 min of contact time, and the water contact angle of the treated fabrics was 133°. The prepared cotton fabrics alsoexhibited excellent stability against 50 abrasion cycles. After 50 washing cycles, 72% of the chlorine content on preparedcotton fabrics could be recovered after rechlorination. And the antibacterial hydrophobic cotton fabrics loaded with TiO2possessed higher UV stability than cotton fabrics only treated with PTSAMS-Cl. Furthermore, the breaking strength ofantibacterial hydrophobic cotton fabrics was decreased while the wrinkle resistance was improved.
