A novel method for preparing microfibrillated cellulose from bamboo fibers

Abstract

The bamboo fiber is a potential candidate for biomass and power source application. In this study, microfibrillated cellulose (MFC) is prepared from raw fibers of bamboo tree (Bambusa Blumeana J A & J H Schultes) by an alkali treatment at room temperature in association with a bleaching treatment followed by a sulfuric acid hydrolysis. Field-emission scanning electron microscopy (FESEM) images indicated that final products ranged from 20 to 40 nm in diameter. The chemical composition measurement and Fourier transform infrared (FTIR) spectroscopy showed that both hemicellulose and lignin are mostly removed in the MFC. The x-ray diffraction (XRD) results also show that MFC has crystallinity of more than 70%. The thermogravimetric analysis (TGA) curves revealed that cellulose microfibers have a two-step thermal decomposition behavior owing to the attachment of sulfated groups onto the cellulose surface in the hydrolysis process with sulfuric acid. The obtained MFCs may have potential applications in alternative power sources as biomass, in pharmaceutical and optical industries as additives, as well as in composite fields as a reinforcement phase.

Thermomechanical Properties of Jute/Bamboo Cellulose Composite and Its Hybrid Composites: The Effects of Treatment and Fiber Loading

“…These characters imply the -glycosidic linkages between the anhydroglucose units in cellulose. The rise of intensity peak at 1026-1020 cm −1 region confirms that the cellulose content increases due to chemical treatment [33]. Both jute and bamboo cellulose show identical peaks compared to commercial cellulose.…”

Characterization of Alkaline Treatment and Fiber Content on the Physical, Thermal, and Mechanical Properties of Ground Coffee Waste/Oxobiodegradable HDPE Biocomposites

“…The reduction of hemicellulose and lignin content is evident from the decreasing in 1250 cm −1 bands compared with untreated GCW. Peaks in the range of 1020-1026 cm −1 represented cellulose [31]. These peaks show higher intensity after treatment.…”

“…The temperature used for thermoforming HDPE was around 180 to 200 ∘ C [19] and lignocellulosic fibers were having complete thermal degradation above 400 ∘ C [31]. However, all of the composites were having high onset degradation temperature (460 ∘ C-462 ∘ C).…”

Preliminary study for acetylation of cassava bagasse starch and microfibrillated cellulose of bamboo

“…MFC bamboo was homogenized in size by high energy milling. This preparation was conducted with slight modification of previous research [23][24]. Both acetylation was considered to follow Kumoro & Amalia (2015) procedure [25] and also degree of substitution (DS) for BS and bamboo MFC.…”
