A novel approach for isolation of nanofibers from sugarcane bagasse and its characterization for packaging applications

Abstract

A novel approach including only one stage of ecofriendly treatment, by sodium bicarbonate, followed by mechanical grinding was used to isolate the nanofibers from waste sugarcane bagasse subjected to its characterization for the packaging applications. The result of dynamic light scattering (DLS) analysis was found in line with the result of transmission electron microscopy (TEM) to confirm the nanosize of developed nanofibers. The X-ray diffraction analysis showed the highest crystallinity of nanofibers than those of untreated and treated fibers. The removal of hemicelluloses and lignin from treated fibers and nanofibers was confirmed by Fourier transform infrared (FTIR) analysis. Moreover, a good thermal stability of nanofibers was also confirmed by thermogravimetric analysis (TGA). The optical properties (ie, absorbance and transmittance) in wavelength range 200 to 700 nm were also measured using UV-visible spectroscope. An excellent optical and antibacterial property against Escherichia coli (E. coli) and Bacillus bacteria along with better strength and stiffness was offered by the isolated nanofibers, which makes them the most suitable reinforcement to be used in polymeric composites for the packaging applications.

Synthesis of 3‐carene‐derived nanocellulose/1,3,4‐thiadiazole‐amide complexes with antifungal activity for plant protection

“…Sugarcane ( Saccharum officinarum L.) is a renowned agricultural product. As a by‐product of the sugar industry, bagasse, which is rich in cellulose, has a wide range of applications as fuel, pulp and paper production, products based on fermentation and packaging industry because of its eco‐friendliness, biodegradability, renewability, low cost, and easy availability 9,10 . Nanocellulose can be obtained from the physical and/or chemical treatment of bleached bagasse pulp, 11 but the strong polarity of its surface makes it not compatible for loading hydrophobic bioactive compounds 12 .…”

Acoustic performance of natural fiber reinforced polymer composites: Influencing factors, future scope, challenges, and applications

“…[19][20][21] Natural acoustic materials are considered as a possible alternative to typical synthetic materials as they have lower environmental impact than traditional materials. [22][23][24][25][26][27] Natural materials have great thermal insulation properties, are often light, and are not harmful to human health, in addition to their acoustic qualities. [28][29][30][31][32] The use of natural fiber reinforced polymer composite materials for noise reduction applications has been steadily growing in recent years.…”

Influence of surface treatments and coupling agents on the thermal and thermo‐mechanical properties of yerba mate/post‐consumer polypropylene composites

“…[7] Natural fibers such as flax, jute, kenaf, sisal, ramie, bamboo, and hemp present low cost, low density, easy access, high specific resistance, good thermomechanical properties, and degradability. [8][9][10][11][12][13] Compared to synthetic fibers, natural fibers are also less polluting during production, with smaller consumption of energy, thus resulting in lower emission of CO 2 . When compared with the glass fibers, natural fibers generally consume 60% less energy in their production process.…”
