“…The prominent peak at 2921 cm -1 of modified lemongrass fiber is due to the C-H stretching from saturated aliphatic compounds. This stretching peak corresponds to the aliphatic moiety in cellulose (Cherian et al 2008). The band at about 1739 cm -1 is due to the C=O stretching of the acetyl group and linked to the ester linkage of carboxylic group of the ferulic acid and p-coumaric acid of lignin (Sun et al 2005).…”

Lemongrass fiber was analyzed to determine the chemical proportion of its lignocellulosic components. Fibers' thermal behavior, surface structures, and functionality were assessed by thermogravimetric analysis (TGA), scanning electron microscope (SEM), and Fourier transforminfrared spectroscopy (FT-IR), respectively. High-density polyethylene (HDPE) matrix composites filled with varying (10%, 20%, 30%, 40%, and 50%) fiber content were prepared and investigated. Composite wicker was made from HDPE and low density polyethylene (LDPE) blend-matrix and 10% alkaline modified fiber. Alkaline or maleic anhydride grafted polypropylene (MA-g-PP) was used to improve the compatibility between the fiber and matrices. The composites were evaluated by using TGA, SEM microscopy, and universal testing machine, respectively. The fiber was constituted by equitable amounts of lignocellulosic components with cellulose accounting for the highest proportion. It also exhibited high degradation temperature, which was further increased following alkaline modification. Superior thermal degradation behavior was measured for modified fiber composites. SEM showed that the modified fiber composites demonstrated better compatibility. Lemongrass fiber reinforcement substantially improved the mechanical properties of the composites.

“…As per the procedure reported by Bibin Mathew cherian and his coworkers [27], the isolation of microcrystalline cellulose from the banana fiber was done using the steam explosion method. The complete extraction of microcrystalline cellulose from banana fiber was done by the combined chemical (acidic) and mechanical treatments.…”

The antimicrobial potential of the synthesized ternary nanochitosan (NCS)/sodium alginate (SA)/microcrystalline cellulose (MC) (extracted from banana fiber) film in 4:16:1 ratio against Bascillus subtilis and E. coli are reported here. Initially the present work focuses on the synthesis and characterization of ternary nanochitosan (NCS)/sodium alginate (SA)/microcrystalline cellulose (MC) (extracted from banana fiber) film. The prepared NCS/SA/MC film sample was then characterized using advanced analytical techniques such as FT-IR, XRD, TGA, DSC and SEM studies. The obtained results of FT-IR studies clearly indicate that the nanochitosan gets effectively binded with the sodium alginate and the microcrystalline cellulose in the film form. The change in crystallinity and the increased thermal behavior was elucidated from XRD and TGA analysis respectively. The scanning electron microscopic (SEM) studies of NCS/SA/MC film showed that the prepared film has the improved rough surface morphology and fractured structure. The bactericidal action of NCS/SA/MC film determined using Muller Hinton Agar medium on two microbial strains (Escherichia coli and Bacillus subtilis) reveals that the prepared NCS/SA/MC film has the greater potential to kill the microorganisms to a greater extent and hence this NCS/SA/MC film was found to be suggested as the promising material for biomedical applications.

In polymer science lignocellulosic fiber-reinforced polymer composite materials have appeared in a wide range area. The composite made from those varieties of materials are low density, low value, comparable certain properties, and most importantly they're environmental friendly. Although a number of the properties linked to composites generated from oil palm fibers and polymers (namely, those that are accessible through commerce) display aspects of commonality when compared to conventional synthetic fiber composites, such properties depend to a significant degree on the extent to which the fibers and matrix phase is compatible with the capacity to absorb moisture. Importantly, this emerges as a key concern and, moreover, disadvantages of Lignocellulosic fibers polymer composites and studies have suggested that it has a considerable impact on the composites' physical and mechanical properties. The central aim of the current paper is to provide an overview of the extant research relating to Lignocellulosic fibers reinforced polymer composites, and particular attention will be directed towards the physical structure and constituent chemical components of Lignocellulosic fibers.
