“…The comparison of the results from the analysis of the chemical composition of the Cymbopogan citratus fiber with different natural fibers is presented in Table 1. A total of 37.6% cellulose was found on the fibers' surface, of the Cymbopogan citratus fibers, which was relatively higher than other natural fibers, e.g., bamboo (26 to 43%) (Kulandaivel et al 2020), Mikania micrantha Kunth (21%) (Ganapathy et al 2019), piassava (28.6%) (Indran and Raj 2015), coconut tree leaf sheath (27%) (Indran and Raj 2015), and less than Carica papaya (58.71%) (Arul Marcel Moshi et al 2020), Nendran banana (73.2%) (Manimaran et al 2020), Saharan aloe vera (67.4%) (Balaji and Nagarajan 2017;Manimaran et al 2020), and sugar palm (44.53%) (Huzaifah et al 2017). Researchers in this field have stated that with a higher cellulose content, the mechanical properties comprising elasticity modulus and tensile strength are improved.…”

“…In this study, a hemicellulose content of 29.3% was found on the surface of Cymbopogan citratus fiber. The lignin content of Cymbopogan citratus fiber was 11.1%; it acts as a protective guard against bacterial attacks (Balaji and Nagarajan 2017). The lower amount of ash (4.28%) for Cymbopogan citratus fiber can explain its mechanical properties, such that the Cymbopogan citratus fiber has the essential properties for use as a potential reinforcement material.…”

A novel natural fiber derived from the Cymbopogan citratus plant was investigated for the first time. The characterization of the C. citratus fibers was conducted, and the chemical composition and physical, thermal, mechanical, crystallinity, and morphological characteristics were studied. The chemical composition analysis of Cymbopogan citratus fiber revealed that the suggested fiber was rich in cellulose contents (37.6%). The tensile test of C. citratus fiber demonstrated the fiber’s average tensile strength of 43.81 ± 15.27 MPa and modulus of elasticity of 1.046 ± 0.33 GPa. Further analysis with X-ray diffraction (XRD) confirmed that the crystallinity index of Cymbopogan citratus fiber was 35.2%, and the crystalline size was estimated as 4.28 nm. The Cymbopogan citratus fiber’s thermal stability was investigated via thermogravimetric analysis (TGA) and observed to be thermally stable (230 °C). A morphological investigation was employed on the fiber via a scanning electron microscope (SEM). The morphological study result exhibited that the fiber had a perforated and rough surface with the lumen in the center. Thus, the findings revealed that the Cymbopogan citratus fiber was a promising potential reinforcement for thermoplastic green composite applications.

A novel cellulosic fibre was extracted from the peduncle portion of the fish tail palm tree and the extracted fish tail palm fibre was treated with different concentrations (1%, 5%, and 9%) of silane solution. The characteristic analysis on chemical, functional, mechanical and surface property of the extracted fish tail palm fibres were investigated through chemical composition analysis, Fourier Transform InfraRed spectroscopy (FT-IR), single fibre tensile test, and Scanning Electron Microscopy (SEM). Chemical analysis results indicate that silane treatment improved the cellulose content of the fish tail palm fibre. The highest cellulose content of 72.51% was observed in the 9% silane treated fish tail palm fibre. Also, it improved crystallinity index value of 62.5% for 5% silane treated fibre, which is confirmed through the X-ray diffraction analysis. FT-IR result indicates the removal of hemicellulose at characteristic wavelength of 1745 cm −1 for 5% silane treated fish tail palm fibre. Tensile property of the silane treated fish tail palm fibre (1, 5, and 9%) shows an increased tensile strength of 7.3%, 12%, and 6.6% as compared to raw fish tail palm fibre. Moreover, this type of novel natural fibres can reduce the cost while offering competent performance during the polymer-based product development.

Crafting ecological materials from green resources is posing a significant challenge for the researchers and scientists around the globe and has resulted in the development of nanocellulose materials, which has paved the way for enriching the basic knowledge and many opportunities on developing biobased materials. This has augmented the utilization of carbohydrate-based organic materials and successfully replacing conventional nonrenewable materials. Cellulose nanomaterials (CNMs) belonging to the newer emerging field of nanomaterials are finding increasing interest among the investigators owing to their environmentally sustainable characteristics like biodegradability, biocompatibility, and potential availability in abundance at a cheaper price. The present review article intends to provide a detailed insight about the advancements and various challenges postured in the field of cellulose nanocrystals (CNCs) and cellulose nanofibers (CNFs). The article further discusses about different cellulose fiber extraction sources and their methods, purification processes employed, various sample preparation and drying techniques used for CNCs and CNFs. The article also outlines the various characterization methods practiced for scrutinizing CNCs and CNFs when used in polymer matrix composites. Finally, the benefits of using the CNMs in several potential applications such as paper, oil and gas industries, food packaging and structural sectors, conductive ink and water purification areas, medical and printed electronic fields are highlighted in this extensively reviewed article.
