Morphologies and properties of lignocellulose fiber extracted from Typha leaves with potential for composite applications

Chemical extraction of lignocellulosic fibers from plant leaves requires the control of process factors so that the cellulosic structure of the fibers is not destroyed, and the resulting fibers are extracted with desirable physical properties. Studies have shown that extraction treatment at high tem...

Description
Summary:Chemical extraction of lignocellulosic fibers from plant leaves requires the control of process factors so that the cellulosic structure of the fibers is not destroyed, and the resulting fibers are extracted with desirable physical properties. Studies have shown that extraction treatment at high temperatures leads to the greater penetration of chemicals and better separation of fibers from non-cellulosic substances in the plant structure. In this study, fiber extraction from Typha leaves at 120 °C with sodium hydroxide during 30-90 min was studied, and the structure of the obtained fiber was investigated using Fourier transforms infrared (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA), scanning electron microscopy (SEM), EDS density mapping, and tensile tests. Also, to evaluate the applicability of the resulting fibers in composites, the pull-out test was used. The results showed the possibility of extracting fiber with suitable properties at a low alkali concentration and a short duration at this temperature.
