TL;DR: In this article, the chemical treatment of banana fiber (Musa sapientum) using sodium hypochlorite NaClO/H2O (1:1) at 60°C is discussed.
Abstract: Environmental consciousness and increasing awareness of green technology have stirred the entire gamut of industry to move toward new materials instead of using synthetic polymeric fibers. Natural fiber can be a good substitute as they are available in fibrous form at low cost. In this study, the chemical treatment of banana fiber (Musa sapientum) using sodium hypochlorite NaClO/H2O (1:1) at 60°C is discussed. The purpose of chemical treatment is to improve the fiber-matrix compatibility, interfacial strength, physical, and thermal properties, etc. The chemical composition of fibers on treatment indicated increase of cellulose content and decrease of noncellulosic material. The changes due to chemical treatment were analyzed by Fourier transform infrared and X-ray diffraction methods. Scanning electron microscope studies revealed the changes in surface morphology after chemical treatment. And also, the treated fibers showed reduced water uptake and improved thermal properties.

TL;DR: In this paper, the morphology and chemical properties of coir pith were modified to make it better filler in the processing of polymer composites, which resulted in increased density, thermal stability and reduced water retention behavior.
Abstract: Coir pith is one of the most abundant agro waste found in the southern coastal regions of India, where the economy and livehood of people are largely dependent on the coconut industry. Many technologies have been developed successfully for the alternate use of coir pith. However the application of coir pith as fillers in polymer composite is limited. The major drawback of coir pith as filler in polymer is its low adhesion with the matrix and high water sorption and retention behavior. The present work is a part of research work carried out in our laboratory to modify the morphology and chemical properties of pith to make it better filler in the processing of polymer composites. Coir pith was subjected to mercerization followed by different types of chemical treatment. The products were analyzed in detail using FTIR, XRD, optical microscope, AFM and SEM. The chemical treatment resulted in increased density, thermal stability and reduced water retention behavior.
