Various raw materials including plant biomass, bacteria, algae and the Tunicates (marine animals) have been used to produce cellulose. However, agricultural waste has rarely been utilized for this purpose. In this work, Sugarcane bagasse was used as raw material to produce cellulose. Cellulose was extracted from sugarcane bagasse through the elimination of lignin and hemicellulose. Cellulose was then converted to carboxymethyl cellulose (CMC b ) by using sodium monochloroacet (SMCA) and various sodium hydroxide (NaOH) concentrations. Fourier Transform Infrared Spectroscopy (FTIR) was applied to verify the effect of NaOH concentration on this property. The highest viscosity and degree of substitution (DS=0.78) were observed in 30 gr/100 ml NaOH of carboxymethylation. Maximum tensile strength of the films produced at these conditions was 37.34 Mpa. The addition of a various amount of glycerol (1 ml/ 100 ml, 2 ml/ 100 ml, 3 ml/ 100 ml) dramatically decreased the tensile strength. The highest level of water vapor permeability was also observed at the same NaOH concentration. Cellulose can be correctly extracted from sugarcane bagasse and converted to carboxymethyl cellulose. Based on the cellulose of the bagasse characteristic, proper amount of NaOH was found to get a high DS. CMC b has considerable features for application on biodegradable coating materials.

“…Cellulose nanostructures are isolated through several topdown approaches including mechanical treatments such as cryocrushing [5], ultra-fine friction grinding [6,7], highpressure homogenizing [8], chemical treatments such as acid hydrolysis [4,9], ultrasound [9,10], enzyme-assisted hydrolysis [11], TEMPO-mediated oxidation [12], and solvent-assisted isolation [13]. Two or more of these methods have also been combined to produce different types of nanostructure cellulose.…”

The aim of this work was to prepare nanocellulose (NC) from beer industrial residuals (BIR) by an acid hydrolysis/ultrasound method using three hydrolysis times (2, 4, and 6 hours). The atomic-force micrographs showed that the obtained NCs had whisker, oval, and spherical shapes. The average diameters of the NCs ranged between 73 and 146 nm. The chemical characterization of BIR and purified cellulose confirmed that α-cellulose content increased from 44 % to 92 % and lignin contents decreased from 32 % to 5 %. FT-IR analysis showed a substantial change in chemical structure of NCs (especially over the 2-hour hydrolysis time) compared to that of purified BIR fibers. XRD results revealed that the NCs' crystallinity and crystallite size were positively affected by acid-hydrolysis time. TGA results showed that the thermal stability of NCs increased as a result of hydrolysis. BIR, a low-value residue, was turned to nanocellulose, a highperformance nanomaterial.

“…The resulting NanoFibrillated Cellulose (NFC) is a renewable, low-cost component in many advanced nanostructured materials, including nanopapers (Henriksson et al, 2008), foams (Aulin et al, 2010), aerogels (Sehaqui et al, 2011) and biocomposites (Capadona et al, 2009;Yousefi et al, 2011). NFC films and foams have potential applications in the packaging industry as sustainable alternatives to petroleum-based solutions.…”

Mechanosorptive creep in nanocellulose materials

et al. 2012

The creep behavior of nanocellulose films and aerogels are studied in a dynamic moisture environment, which is crucial to their performance in packaging applications. For these materials, the creep rate under cyclic humidity conditions exceeds any constant humidity creep rate within the cycling range, a phenomenon known as mechanosorptive creep. By varying the sample thickness and relative humidity ramp rate, it is shown that mechanosorptive creep is not significantly affected by the through-thickness moisture gradient. It is also shown that cellulose nanofibril aerogels with high porosity display the same accelerated creep as films. Microstructures larger than the fibril diameter thus appear to be of secondary importance to mechanosorptive creep in nanocellulose materials, suggesting that the governing mechanism is found between molecular scales and the length-scales of the fibril diameter.
