“…On the other hand, cellulose is a polysaccharide polymer with a high concentration of glucose monosaccharide units. Lignin, an amorphous natural polymer, is constituted of guaiacyl, syringyl, and p‐hydroxyphenyl units 34 . However, the amount of hemicellulose, cellulose, and lignin in oxidized samples was lower than in untreated samples (Table 3).…”

“…Lignin, an amorphous natural polymer, is constituted of guaiacyl, syringyl, and p-hydroxyphenyl units. 34 However, the amount of hemicellulose, cellulose, and lignin in oxidized samples was lower than in untreated samples (Table 3). It is due to the destruction of the amorphous area, the reaction in cellulose walls, and lignin polymers during APS treatment.…”

“…32 Recently, Kolya et al reported that oxidation treatment on the oak and malas hardwood cell walls could improve sound absorption. 33,34 However, APS treatment on monocotyledon species (Coconut wood) has not been studied yet. This study aims to increase the SAC of Cocos nucifera L. wood species to improve the utilization of wood to control noise pollution.…”

The rational design of sound absorption boards made of wood materials is an attractive field of research. This article describes a simple and low‐cost ammonium persulfate treatment on coconut wood cell walls (Cocos nucifera L.). Reaction parameters such as concentration of reactant and reaction time were optimized. The results of different instrumental characterization such as X‐ray photoelectron spectroscopy, X‐ray diffraction, attenuated total reflectance–Fourier transforms infrared spectroscopy, and scanning electron microscope supports the chemical alterations of the wood cell wall. The quantitative analysis of hemicellulose, cellulose, and lignin was performed. The significant changes in cell‐walls enhanced average sound absorption coefficient at each frequency range: 60.4% at 500–1000 Hz (t = −10.593 and p < 0.001), 80.8% at 1000–2000 Hz (t = −4.798 and p < 0.001), 96.2% at 2000–4000 Hz (t = −58.527 and p < 0.001) and 83.0% at 500–64000 Hz (t = −51.261 and p < 0.001). It is due to the increment of gas permeability (288.3%, p = <0.001). These results could be beneficial for new research on wood‐based sound absorption materials to regulate the acoustic environment in houses.

“…7 As for porous organic materials, polyurethane and polyvinyl chloride, for instance, although they exhibit the merits of low cost and simple preparation, their disadvantages, such as low thermal stability and weathering resistance, limit their longterm applications. [8][9][10][11] Filip et al prepared nanobrous mats by electrospinning blends of virgin and recycled poly(vinyl butyral), and these organic systems exhibited good soundadsorbing performance. 12 Porous metallic materials, such as copper and aluminum, generally demonstrate the advantages of high temperature resistance and re retardancy, while they exhibit the limitation of low chemical stability.…”

The chemical, physico‐mechanical, morphological, and thermal characteristics of alkali treated natural cellulosic sustainable eco‐friendly fiber from peduncle of Areca Catechu tree were investigated. Areca Catechu fruit peduncle fiber (ACFPF) treated with 5% (w/v) NaOH solution for 60 min is found as optimally alkali treated ACFPF (OAACFPF) witnessed an increase in cellulose content by 17%. Single fiber tensile test perceived that OAACFPF enhanced tensile strength by 12.9% and x‐ray diffraction analysis depicts crystallinity index of OAACFPF improved by 14.2% compared with ACFPF. Also, Fourier transform infrared spectroscopy analysis endorsed partial removal of amorphous contents from fibers due to alkali treatment. In addition, alkali treatment has enhanced thermal stability of OAACFPF from 226°C to 235°C verified through Thermogravimetric analysis. Likewise, Differential scanning calorimetry analysis confirmed improvement in thermal degradation temperature of OAACFPF after alkali treatment. Moreover, the rougher surface of OAACFPF confirmed through scanning electron microscope and atomic force microscopy is due to partial removal of amorphous contents thus ensuing in good interfacial bonding characteristics with the matrix during reinforcement for bio‐composite fabrication. The above findings validated OAACFPF as a worthy substitute to harmful synthetic fibers for development of eco‐friendly and sustainable bio‐composites.
