Structural and thermal characterization of cellulose and copper oxide modified cellulose obtained from bamboo plant fibre

Abstract

Cellulose and their modified forms are important materials for various applications including surface coatings, food and drug formulations, and confectioneries and as intermediates for other chemical products. This study focuses on the nonconventional production of cellulose from abundant bamboo plant and the structural effects arising from modifications of the obtained cellulose. The bamboo fibre was treated with alkali and bleached to produce cellulose which was further modified with ethylene and propylene oxides and CuO nanoparticles. They were characterised with Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), energy dispersive X-ray and thermogravimetric analyser-differential scanning calorimeter (TGA-DSC). This approach gave interesting structural differences among the cellulose and the modified forms. From the TGA analyses, the CuO nanoparticles impregnated cellulosic material exhibited the greatest stability. The raw bamboo fibre appeared as stacked porous nanotubes as shown by the SEM different from other morphologies while the FTIR displayed similar peaks with minor differences. The nature and behaviour of the modified cellulosic materials suggest applications especially in paint formulation and as nano carriers.

Synthesis, Characterization, and Adsorptive Characteristics of Radiation-Grafted Glycidyl Methacrylate Bamboo Fiber Composites

“…VMBF exhibits only a single-step degradation profile in the range of 270–340 °C due to the cellulose and hemicellulose decomposition behavior. The TGA curves of VMBF- g -PGMA exhibit a higher thermal stability of developed biopolymer due to the formation of higher-molecular-weight polymers . Because of the removal of water from ambient temperature to 120 °C, the first mass loss occurred.…”

The second mass loss was observed from 120 to 286 °C because of the decomposition of pendent groups.…”

Production and Application of Cellulose, Dietary Fiber, and Nanocellulose from Bamboo Shoot

“…As listed in Table 1, BSC has successfully been extracted from bamboo plants by chemical, physical, biological, and combinational methods to name a few. The hydrothermal treatment with NaOH and NaClO 2 has been found an effective method to prepare BSC, and these chemical reagents aim to remove hemicellulose and lignin of BSSF, and then BSSF was treated with alkali and bleached to produce BSC [34]. To protect environment, the environmental protection oxidant sodium percarbonate combined with alkali oxygen bath method was used to prepare BSSF.…”

Characteristics of Mechanical Strength of Hybrid Reinforced Plastic Waste Mixed with Wood Waste

“…To mitigate plastic waste management and disposal capacity, there is a growing interest in the development of newer, promptly perishable plastics and the biodegradation of typical plastic waste for circular [19]. Many materials are capable of reinforcing polymers, such as cellulose in wood, which is a naturally occurring product [20]. Although many forms of fibers are used as reinforcement in composite laminates, glass fibers account for more than 90% of reinforced plastics due to their low cost and relatively good strength-to-weight characteristics.…”
