The cellulose nanocrystal (CNC)-Ag@AgCl was prepared by previously adding silver nitrate to a cellulose solution with PVP, then hydrolyzed using sulfuric acid under visible light. In this method, Ag@AgCl could be firmly attached to the CNC surface without using any reducing agent. Experimental data obtained from energy dispersive spectrometry, X-ray photoelectron spectroscopy and X-ray diffraction...
Cellulose–Ag@AgCl composite films were fabricated by one-step coagulation of the cellulose/1-Butyl-3-methylimidazolium chloride (BmimCl)solution with AgNO3. AgCl was firstly formed when AgNO3 was added into cellulose/BmimCl solution, and then the formed AgCl was further reacted with excess Cl−, leading to the complete dissolution of AgCl. The AgCl crystal would grow again from cellulose matrix in...
In this work, cellulose–Ag@AgCl composite films have been fabricated directly through a one-step coagulation of a cellulose/1-butyl-3-methylimidazolium chloride (BmimCl) solution with AgNO3 and PVP. The AgCl was formed upon the addition of AgNO3 to a cellulose/BmimCl solution, and underwent further reaction with excess Cl−, leading to the complete dissolution of AgCl. The AgCl crystals were regenerated...
Residual ethanol was used as an activation agent to control the status of corn cellulose (CN cellulose) solution and thereby the morphology of CN cellulose fibers after electrospinning. A suitable amount of ethanol could combine with the CN cellulose chains to reduce their ionic absorbance, improving the migration ability of ions in the cellulose–N,N-dimethylacetamide (DMAc)/LiCl–ethanol system. As...
Regenerated cellulose blend film with thermoplastic polyurethane (TPU) was successfully prepared by coagulating cellulose/TPU solution with water in the presence of a thermoplastic polyurethane elastomer (TPU). Compared with pristine regenerated cellulose film, the toughness and thermal stability of the blend film was significantly improved. For example, the elongation at break was increased from...
