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...
Due to energy crisis and environmental pollution, biopolymer-based packaging materials have been extensively investigated. Cellulose nanofibrils (CNFs), due to their good oxygen barrier performance and excellent mechanical as well as film-forming properties, have emerged as interesting packaging materials. However, the problem of the resulting films is the highly hygroscopic character of the cellulose...
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...
The rheology and printability of the mixture from carboxymethyl tamarind gum (CTG) and carboxymethyl starch (CMS) with different mixture ratios were studied to explore the availability on double-sided printing of georgette fabric. The rheological properties of the mixture from CTG and CMS (TS) were investigated by steady-shear, dynamic oscillatory and transient tests. The printing performances of...
We report a study on the synthesis of a nanocomposite that contains anatase titania (TiO2) particles, organo-montmorillonite (OMMT) and cellulose-g-poly(methyl methacrylate) (cellulose-g-PMMA), and the application of the nanocomposite as a photocatalyst in degradation of 2,4-dichlorophenol (2,4-DCP). The nanocomposite was characterized by Fourier-transform infrared spectra, X-ray diffraction, transmission...
A novel method for the preparation of composites based on poly(vinyl alcohol) (PVA) and micro- and nano-fibrillated cellulose (M/NFC) is reported. The addition of crosslinking HEMA monomers and a photo-initiator enabled the formation of an interpenetrated polymer network that displayed enhanced interfacial adhesion and dispersion of (M/NFC) in the matrix. Photo-crosslinked PVA/(M/NFC)/polyHEMA composite...
We report a study on the synthesis of cellulose-g-poly(methyl methacrylate)/organo-montmorillonite and its application in the removal of 2,4-dichlorophenol (2,4-DCP) from aqueous solution. The nanocomposite of cellulose-g-PMMA/OMMT was synthesized by using atom transfer radical polymerization. We investigated the effects of four reaction parameters on the grafting efficiency and percentage. The nanocomposite...
A flame retardant nanocoating made from chitosan and titanate nanotubes was deposited on the surface of cotton fabric by the layer by layer assembly to improve its flame retardancy. Firstly, the hydrothermal method was used to prepare titanate nanotubes. Then, coated cotton fabrics were prepared by alternately submersing cotton fabrics into chitosan solution and titanate nanotube suspension. The structure...
An amino-terminated aliphatic hyperbranched polymer (HBP-NH 2 ) was used to modify ramie fabric. The molecular weight of HBP-NH 2 was established by GPC. HBP-NH 2 structure might represent as BA 4 BA 3 BA 3 (third generation). The total amine value, secondary amine value and primary amine value of HBP-NH 2 were...
Cellulose nanowhiskers (CNWs) were chemically modified with dodecenyl succinic anhydride to obtain hydrophobic CNWs called DCNWs. Surface modification was confirmed by infrared spectroscopy, transmission electron microscopy, and X-ray diffraction. The surface substitution degree determined by X-ray photoelectron spectroscopy was 0.30. Nanocomposites were prepared by incorporating different amounts...
A new amino-terminated hyperbranched polymer (at-HBP) was synthesized, and its salt-free dyeing property on ramie fabric was studied. The structure and molecular weight of at-HBP were established by Fourier transform infrared spectrometer, H nuclear magnetic resonance and gel permeation chromatography. The untreated ramie fabric and modified ramie fabrics were characterized by an X-ray diffraction...
