“…A few bands in the 1500-1200 cm -1 region to both CH 2 deformations and C-O-H bending vibrations, and intense bands in the 1200-900 cm -1 region are attributed to the stretching modes of C-O and C-C vibrations. The bands from 800 to 700 cm -1 represent the contributions from two crystalline forms of cotton cellulose, in which the type of cellulose is associated with the plant's origin and can directly influence the mechanical properties of cotton [59][60][61][62] .…”

Biocomposites have gained attention in the packaging industry due to their potential as sustainable alternatives to conventional synthetic materials. In this study, novel cotton incorporated poly (lactic acid)/ thermoplastic starch biocomposites were developed for packaging applications using in short shelf life products the extrusion method. Pelletized samples obtained by extrusion were stamped from plates obtained by compression and were characterized through measurement of density, hardness, contact angle and water absorption, as well as Fourier transform infrared spectroscopy (FTIR), thermal analysis and scanning electron microscopy (SEM). No significant changes in the density results were observed. A slight increase in the hardness of formulations in relation to the PLA was associated with the presence of cotton fiber in biocomposites. The FTIR results revealed physical interaction of PLA, TPS and cotton fiber. By DSC analysis, for all formulations the melting exhibited only one peak, suggesting good homogeneity and interaction among the components, as observed by TG/DTG results, and corroborating SEM analysis. The biocomposite PLA/TPS/Cotton 85/10/5 wt.% displayed greater increase in water absorption than both 95/5/0 and 90/5/5 wt.% formulations, which can be attributed to the increase in starch proportion, confirming the contact angle results. The hydrophilic tendency corroborated the biodegradation process in the packaging end-of-life.

“…These products are used in the daily lives of families [190]. It is possible to obtain more than 60 products from babassu, many manufactured from the nut, such as oil, "azeite", milk, for both fresh consumption and industries like food, cleaning materials, personal hygiene, cosmetics, as well as charcoal, fertilizers, and other by-products [191][192][193].…”

“…However, the most common extraction method is from the coconut. Chaves et al [193] conducted the extraction of babaçu fibers with the aim of characterizing their properties for potential application in composites. Throughout the study, the authors followed a sequence of steps to obtain the fibers.…”

“…The results indicated a drastic reduction in the properties of the composites after biodegradation, The babassu palm already has a significant history of applications, as mentioned earlier, including the use of its fibers in composites for engineering applications. In addition to the analysis of the properties of the fiber in isolation [193][194][195], the investigation of composite materials using this fiber as a reinforcing agent enables its application in various engineering fields while maintaining a sustainable approach to plastic materials.…”

“…Various studies have been carried out to better understand the characteristics and behavior of this fiber in composites, with the aim of optimizing its use and exploiting its full potential. Cunha et al [193] compared the effect of tucum fibers (Astrocaryum chambira Burret) and mallow fibers in polyurethane (PU) matrix composites. The authors produced composites only reinforced with tucum fibers (TPU) and only with mallow fibers (MPU), in fractions of 30, 50, and 70 wt.%, and the properties of the fibers and composites were analyzed.…”

The Amazon rainforest, spanning multiple countries in South America, is the world’s largest equatorial expanse, housing a vast array of relatively unknown plant and animal species. Encompassing the planet’s greatest flora, the Amazon offers a tremendous variety of plants from which natural lignocellulosic fibers (NLFs) can be extracted. In this century, NLFs, which have long been utilized by indigenous populations of the Amazon, have garnered interest as potential reinforcements for composites, whether polymer- or cement-based, in various technical applications such as packaging, construction, automotive products, and ballistic armor. A comparison with synthetic materials like glass, carbon, and aramid fibers, as well as other established NLFs, highlights the cost and specific property advantages of Amazon natural fibers (ANFs). Notably, the sustainable cultivation and extraction of ANFs, as alternatives to deforestation and livestock pasture, contribute to the preservation of the Amazon rainforest. This review article provides a comprehensive examination of recent studies directly related to ANF-reinforced polymer matrix composites. The specific advantages, proposed applications, and reported challenges are highlighted, shedding light on the potential of these unique natural fibers.
