Preliminary studies performed have indicated that carbon nanotube (CNT) coating is an effective method to enhance the bonding between a natural fiber and a resin matrix. However, the reported coating process is complex, and the improvement of the bonding strength is limited owing to obvious CNT aggregation. This paper reports a simple spray-coating method with uniform distribution of CNTs coated on...
Oil/water separation is highly desired due to increasing industrial oily wastewater and frequent oil spill accidents. Here, superhydrophobic/superoleophilic paper was successfully fabricated by the combination of layer-by-layer (LBL) deposition of chitosan (CS) and hexadecyltrimethoxysilane (HMTS)-g-TiO2 on paper surface and subsequent heat treatment. The formation of CS/HTMS-g-TiO2 multilayers on...
Interest in superhydrophobic paper is growing, and efforts have been made to prepare superhydrophobic paper with an improved physical strength property. This study reported a facile method for fabricating a superhydrophobic paper with enhanced physical strength through layer-by-layer self-assembly of poly(allylamine hydrochloride) (PAH) and lignosulfonates-amine (LSA) on cellulose fiber surfaces,...
To convert the hydrophilic cellulose fiber into hydrophobic, multilayers composed of cationic polyacrylamide (CPAM) and lignosulfonate (LS) were constructed on cellulose fiber surface using layer-by-layer (LBL) self-assembly technique. The presence of CPAM/LS multilayers were validated by zeta potential, X-ray photoelectron spectroscopy and atomic force microscopy (AFM). It was found that potential...
In order to gain an understanding of the process of Lyocell fiber formation, the melting and solidification behaviors, heat capacity and density of cellulose N-methylmorpholine-N-oxide monohydrate (NMMO-MH) solutions were studied by differential scanning calorimetry (DSC) and dilatometry, and the diameter development of Lyocell fibers in the air gap was measured online. It was found that the Lyocell...
