“…In recent years, the requirement for environmentally friendly materials is increasing to reduce the consumption of fossil fuels and prevent global environmental concern [1,2]. Natural reinforced composites are used widely replacing synthetic reinforced polymers, especially for industrial application such as the automotive, construction, and packaging industries [3,4]. Investigations have also been carried out to produce composites from natural fiber using different types of matrices, such as polypropylene [5], polyethylene [6], epoxy [7], and polyhydroxybutyrate [8], which is capable of satisfying many engineering applications in terms of energy, strength, and absorption.…”

Recently, natural fibers have become attractive materials to engineers, scientists, and researchers as an alternative reinforcement for biocomposites. In this study, polylactic acid/abutilon natural straw biocomposites with various abutilon straw weight fractions were prepared by melt blending. The differential scanning calorimetric (DSC) results showed a significant influence of the abutilon straw on the melting behavior of PLA, even at the low abutilon straw contents. The dynamic mechanical analysis demonstrated that the storage modulus, as well as tan delta of the biocomposites, increased when the abutilon straw content increases, which indicates better interaction between abutilon natural straw and PLA. The incorporation of abutilon straw into biocomposites provided favorable changes in rheology related to the matrix. SEM observation revealed good dispersion of the abutilon straw in PLA.

“…However, the tensile strength decreased dramatically on the third day of UV irradiation, and gradually decreased thereafter. Because oxidative degradation and hydrolysis tend to make the polymer brittle, the PA6 specimens were more brittle after UV-C light irradiation [34,35]. However, the PA6/CF composite specimens showed no noticeable difference in tensile strength with increased exposure to UV-C light irradiation.…”

In this research, we demonstrate the effect of ultraviolet-C (UV-C) irradiation of Polyamide 6/carbon-fiber (PA6/CF) composites. The PA6 and PA6/CF composites were fabricated using a fused deposition modeling type 3D printer with a single spool. These specimens were exposed for 0, 1, 3, 5, and 7 days under UV-C light irradiation. After exposure, the specimens were observed and characterized with contact angle measurements, Fourier transform infrared analysis, 3D fluorescence spectroscopy analysis, tensile tests, and scanning electron microscopy. As a result, PA6 was found to be more photo-oxidative degraded than PA6/CF. Furthermore, the 3D fluorescence images and emission spectra were shown to successfully coincide with the results of the photo-oxidative degradation reactions of PA6 and PA6/CF. In addition, the tensile test results showed a dramatic decrease in PA6 while PA6/CF did not decrease much, indicating that CF is useful not only as a reinforcement of the composite but also for UV protection.

“…Accordingly, several studies were performed to evaluate the effect of incorporating natural fibres in biopolymer composites to improve the composite’s mechanical and barrier properties. Among natural fibres, cellulose [ 60 , 61 , 62 , 63 , 64 , 65 , 66 ], hemp [ 67 , 68 , 69 , 70 , 71 , 72 , 73 ], kenaf [ 74 , 75 , 76 , 77 , 78 ] and flax [ 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ] were the most studied ones. It is worth mentioning that nanocomposites of natural fibres or crystals added as fillers without plasticiser or compatibiliser, results in their poor dispersion and decrease the quality of polymer composite.…”

Macro and Micro Routes to High Performance Bioplastics: Bioplastic Biodegradability and Mechanical and Barrier Properties

et al. 2021

On a score sheet for plastics, bioplastics have a medium score for combined mechanical performance and a high score for biodegradability with respect to counterpart petroleum-based plastics. Analysis quickly confirms that endeavours to increase the mechanical performance score for bioplastics would be far more achievable than delivering adequate biodegradability for the recalcitrant plastics, while preserving their impressive mechanical performances. Key architectural features of both bioplastics and petroleum-based plastics, namely, molecular weight (Mw) and crystallinity, which underpin mechanical performance, typically have an inversely dependent relationship with biodegradability. In the case of bioplastics, both macro and micro strategies with dual positive correlation on mechanical and biodegradability performance, are available to address this dilemma. Regarding the macro approach, processing using selected fillers, plasticisers and compatibilisers have been shown to enhance both targeted mechanical properties and biodegradability within bioplastics. Whereas, regarding the micro approach, a whole host of bio and chemical synthetic routes are uniquely available, to produce improved bioplastics. In this review, the main characteristics of bioplastics in terms of mechanical and barrier performances, as well as biodegradability, have been assessed—identifying both macro and micro routes promoting favourable bioplastics’ production, processability and performance.
