“…Cellulose that provided from fibers has many hydroxyl functional groups which makes it potential as a chain extender in polyurethanes polymerization, but there has not been any study that proved it. In last decade, some efforts have converted to several forms like, MFC, microcrystalline (MMC) with several end use application [1]. The aim of this study, is to determine the availability of Sorghum bicolor plant cellulose as a chain extender in polyurethane polymerization.…”

“…It can be infered that higher chlorine content gave better result. It was observed that “ijuk” fibre bundles separate into individual fibre because oxidation could make lignin depolymerized and dilluted to the solution . This fibrillation was mainly attributed to the separation of the fibres primary cell wall due to the removal of hemicellulose and lignin which bind celullose .…”

“…As the result, fiber was easier to be attacked by next process, which was acid hydrolysis. If the lignin is still existed in treated fiber because of insufficient lignin removal, it would cause the lower efficiency of acid hydrolysis . The hydrolysis treatment is expected to annihillate the amorphous parts in MFC by keeping the crystalline parts, however this step did not decrease the diameter of fiber.…”

“…Previous study related to alkalinization with 10% NaOH and oxidation treatment with NaClO which was continued by hydrolysis with 20% H 2 SO 4 has been reported. The result showed that the fiber became fibrillated . Previous paper informed that MFC was used as an emulsion stabilizer, filler in paper, water absorbent, reinforcement in epoxy matrix and biocomposite …”

Summary The applications of micro fibrillated cellulose (MFC) are growing rapidly due to their environment benefit. In the present experiment, MFC from “Ijuk” fibre by chemical method was got. MFC was extracted from the fibre using multistage process, alkaline treatment for the removal of pectin, waxes and impurities on the surface fibre, oxidation treatment with sodium hypochlorite and then hydrolysis treatment with sulphuric acid. The removal of non‐cellulosic components was confirmed by Fourier Transform Infrared (FT‐IR). The treatment lead to increase crystalline part of fibre was demonstrated by X‐Ray Diffraction (XRD). Diameter and surface morphology of MFC was displayed by Field Emission Scanning Electron Microscopy (FESEM). The MFC had diameters in range 5.4‐5.95 µm. Untreated ijuk fibre still had impurities and waxes and the diameter was 54 µm, on the other hand, the fibre became fibrillated after hydrolysis treatment. The feasibility study of MFC for nucleating agent was investigated by Differential Scanning Calorimeter (DSC). The result showed a new approach for utilization of “Ijuk” fibre to examine MFC potential used as nucleating agent in polypropylene (pp) composite application.

Summary The development of micro‐fibrillated cellulose (MFC) is currently a topic of interest among researchers and industry. The aim from this research is to get MFC from sweet sorghum (Sorghum bicolor (L.) Moench), which contains about 45.9% of cellulose. Sorghum also has good mechanical properties that promising to be applied as the reinforcement for polymer matrix. The main challenge to get MFC is the removal of lignin and hemicellulose. Chemical treatments viz. alkalinization (NaOH 20%), bleaching (NaClO 5%) and acid hydrolysis (H2SO4 25%), were applied to sorghum. Different characterizations such as FTIR spectroscopy, Scanning Electron Microscopic (SEM), X‐ray diffraction (XRD), and Simultaneous Thermal Analysis (STA) were used to evaluate this study. FTIR spectroscopy and SEM showed that the chemical treatment effectively reduced lignin and hemicellulose. XRD and FTIR characterization showed the highest crystallinity obtained through alkalinization treatment − acid hydrolysis from 7.5% up to 43.95%. The size of the smallest fibers produced was about 2‐4 microns.
