“…Moreover, the band at 1230 cm -1 , typical of C-O functional group corresponding to aryl-alkyl ether in lignin, disappeared, indicating removal of both hemicellulose and lignin, confirming the results of NMR previously described [35]. The peaks observed at 1603 and 1645 cm -1 can be attributed to the H-O-H stretching vibration of the absorbed water [36].…”

Abstract.1 In this work, jute fiber was used as a source of cellulose fiber. Chemical processes for the purification, mechanical dispersion in Ultra Turrax and modifications with titanium isopropoxide (TiP), 3-aminopropyltrimethoxysilane (APTMS), as well as double modification with both TiP and APTMS, were used to obtain fibers with reduced diameter and less agglomeration and adhesion to polar polymers such as polyamides. Fibers with a diameter close to 10 μm were observed by SEM after drying and pulverization. The fibers subjected to alkaline treatment, acid hydrolysis and doubly modified were well dispersed in water. SEM micrographs revealed the obtainment of fibers with a diameter close to 1 μm for those modified with TiP and APTMS. NMR results exhibited a reduction in the amplitude index accompanied by an increase in the relaxation time and in thickness of the crystalline domains by the removal of lignin and hemicellulose. A contrary effect was observed with the chemical modifications. The results of FTIR and XDR also indicated the removal of lignin and hemicellulose, as did the chemical modifications of cellulose. Increased crystallinity index (CI) was observed with the removal of amorphous components in jute fiber, while CI declined in the fiber modified with both TiP and APTMS. However, TGA results showed higher resistance to thermal degradation for the doubly modified fiber.

“…The tensile strength and modulus increased with increasing MCC content up to 9% but decreased when the MCC content was above 9% due to the aggregation in the composites. These produced composites also showed no cytotoxicity indicating their application in the biomedical field for purposes such as wound dressing [26]. In the endeavor to convert waste cotton fabrics into value-added products, MCC was prepared from the fabric waste and added as reinforcement for melt-processed PVA [27].…”

A Review of Natural Fiber Reinforced Poly(Vinyl Alcohol) Based Composites: Application and Opportunity

et al. 2015

Natural fibers are fine examples of renewable resources that play an important role in the composites industry, which produces superior strength comparable to synthetic fibers. Poly(vinyl alcohol) (PVA) composites in particular have attracted enormous interest in view of their satisfactory performance, properties and biodegradability. Their performance in many applications such as consumer, biomedical, and agriculture is well defined and promising. This paper reviews the utilization of natural fibers from macro to nanoscale as reinforcement in PVA composites. An overview on the properties, processing methods, biodegradability, and applications of these composites is presented. The advantages arising from chemical and physical modifications of fibers or composites are discussed in terms of improved properties and performance. In addition, proper arrangement of nanocellulose in composites helps to prevent agglomeration and results in a better dispersion. The limitations and challenges of the composites and future works of these bio-composites are also discussed. This review concludes that PVA composites have potential for use in numerous applications. However, issues on technological feasibility, environmental effectiveness, and economic affordability should be considered.

“…It can be seen that all samples including UP, RUPC, SUPC and DUPC show similar trend of curve, except for changing intensities. The curve intensity of fibre loaded UP was slightly high due to higher amount of crystallinity [31]. The fibre acted as a nucleating agent which were thought to be the reason behind this statement.…”

In this current study, the mechanical, structural and morphological properties of kenaf fibre based polyester composites based on reinforcing arrangement were investigated. Fibres were placed in layers into the resin to enhance reinforcement. A hand lay-up technique was used to prepare the sandwich composite. Composites were characterized by tensile, flexural and impact testing. The structural properties as well as crystalline behaviour were observed by X-ray diffraction analysis. Additionally, the surface of the fractured samples was also examined using scanning electron microscopy to understand the interaction behaviour between the fibres and matrix. Results of the analyses revealed that single layered kenaf mat enhanced the tensile strength by 80%, whereas the double layered improved by 156%, in the presence of a fixed amount of curing agent. The thermal properties of the composites based on double layered kenaf mat were also found to improve compared to the others. The double layered composites can be used as high temperature-sustained roofing materials to replace traditional products.
