Layered cotton/rGO/NiWP fabric (C/rGO/NiWP) with excellent electrical conductivity and electromagnetic shielding performance was successfully prepared by firstly graphene grafting and then NiWP electroless plating. The design of this layer-by-layer structure fully demonstrated the synergistic effect of wave reflection and wave absorption. The features of C/rGO fabric and C/rGO/NiWP fabric were characterized...
In this paper, a simple method has been developed to fabricate flexible fiber materials with excellent visible light response. Firstly, polydopamine (PDA) layer was deposited on the cotton fibers to functionize cotton fibers. Then, a uniformly dense layer of silver and tungsten trioxide nanoparticles was obtained on cotton fabric by reduction of PDA. The deposition of PDA provided a media for the...
It is often difficult to guarantee the service life of fabric-based superhydrophobic materials that possess self-cleaning and oil–water separation capabilities. To extend practical use, a robust, self-healing superhydrophobic and superoleophilic cotton fabric was successfully prepared by simple impregnation and UV irradiation. The obtained superhydrophobic cotton had a contact angle of 152.4°. The...
Carboxyl functionalized multiwalled carbon nanotubes (MWCNTs-COOH)/cotton flexible supercapacitor electrode is prepared by a simple and efficient method with high conductivity and excellent electrochemical properties. Firstly, MWCNTs-COOH were successfully loaded on the cotton fabric by improved one-time dipping method, while conducted at high temperature and pressure for 2 h can effectively increase...
Cotton fabrics with durable antibacterial properties were prepared by a novel method of thiol-maleimide click reaction. Firstly, 3-Mercaptopropyltriethoxysilane was utilized as a modifier to generate thiol groups on the cotton surface. Then, these thiol groups reacted with N-phenyl-male-imide through thiol-maleimide click chemistry. The surface morphology of the treated fabrics and the reaction mechanism...
The visible light-responsive photocatalyst BiVO4/SiO2/reduced graphene oxide (RGO) was synthesized by hydrothermal method. For easy collection and reuse in slurry systems, RGO/BiVO4/SiO2 was immobilized on the cotton fiber by ultrasonic-heating technology. The characterization results indicated that the surface of cotton fiber was uniformly covered with BiVO4/SiO2/RGO photocatalyst. The loaded BiVO...
Water-repellent finishing of cotton fabrics was carried out using fluorine-free functionalized silsesquioxanes. The modification was performed in two stages: (i) preparation of alkylfunctionalized silsesquioxanes bearing additional triethoxysilyl groups by way of a photochemical thiol-ene click reaction, and (ii) modification of the cotton fibers with these silsesquioxane derivatives. Different ratios...
