Acetylation treatment
Natural fibers are excellent reinforcing materials for polymer composites (thermoplastics, thermosets, and elastomers). Composites based mostly on pure fibers have better impacts in the industry as a result of these fibers have high particular properties and low density. Natural fibers are renewable supplies, relatively excessive in tensile strength, low-cost, and light52. Natural fibers have turn out to be an various choice to non-renewable and expensive artificial fibers (glass, carbon and kevlar fibers)53 in numerous purposes due to environmental aspects and their properties as proven in Fig. Natural fibers comprise some desirable properties, including excessive specific energy and modulus, flexibility throughout treatment, and wonderful corrosion resistance53. However they show some limitations similar to high anisotropy, moisture absorption, limited compatibility with typical resins, and inferior homogeneity when compared to glass and carbon fibers55,fifty six.
Current Innovations in Sustainable Packaging
Biocomposites with treated pure fibers have higher energy levels than biocomposites with untreated fibers. Biocomposites have decrease elongation at break than PLA at fiber loading 5–20 wt%, as illustrated in Fig. It was found that the brittleness of PLA composites is larger than that of neat PLA. This is due to the rigid nature of the reinforcement of wet coir fibers with the PLA matrix. When fiber loading reaches 30% within the composite, these composites have a high elongation at break in comparison with polylactic acid.
