A novel preparation route of zinc oxide (ZnO)-cellulose composite was developed. The ZnO-cellulose composites were produced by using filter paper impregnated with aqueous solution of zinc chloride (ZnCl2) via reaction by sodium hydroxide (NaOH) aqueous solution. Filter papers were pressed for 5 minutes at 3.85 kPa between two clear plastic sheets at an ambient temperature after impregnated by a 65 wt % ZnCl2 at a fixed temperature for several seconds. The impregnated filter papers were impregnated in 0.8 wt % sodium hydroxide (NaOH) solution for one hour, followed by rinsing with deionized water for several times. The ZnO-cellulose composites can be formed. The composites was investigated using a Fourier transform infrared (FT-IR) spectrometer, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), a scanning electron microscope (SEM) and mechanical properties. The results demonstrated that the ZnO-cellulose composite showed a high compactness, a double increase in both tensile strength and bursting strength compared with the untreated cellulose paper. Moreover, folding strength was enhanced more than fifteen times. Filter fibers treated according to this method had the skeleton of un-dissolved cellulose fibers, the matrix of gelled cellulose and flower-like ZnO nano rods on cellulose. In addition, the ZnO-cellulose composites showed excellent antibacterial property.
