“…Figure 4(c) shows that the binder of MAPP in the composite caused further improvement in the distribution and adhesion between the two phases (Digabel et al 2004). The use of a coupling agent reduces stress concentration and promotes this energy for the enhancement of cracks (Sain et al 2004).…”

Composite production of polypropylene polymers was considered in this work as the matrix, filled with the fiber of wheat straw and paper mill sludge; different ratios were evaluated relative to their potential as reinforcement materials. Maleic anhydride polypropylene (MAAP) was used at 3% by weight. The bending modulus of elasticity of the composites significantly increased with both types of filler. The highest bending modulus of the composites was found with 40% of paper mill sludge. Using 40% wheat straw fiber decreased bending strength, but the addition of paper mill sludge increased bending strength. The highest bending strength of the composites related to polypropylene/10% of wheat straw fiber and 30% of paper mill sludge. In terms of impact strength, the use of paper mill sludge had a higher impact on strength than wheat straw fiber composites. The inclusion of MAPP improved the mechanical properties of all composites. Scanning electron micrographs showed that the composite paper mill sludge improved the adhesion and dispersion of the filler (paper mill sludge/fiber paper instead of wheat) in the matrix.

“…The combination of PBAT-based composites have been reported by several research groups using different fillers, such as cellulose nanocrystals (CNC) [71,73], montmorillonites (MMT) [74,75], natural fibers [76,77], nanofibrillated cellulose (CNF) [78], red mud [79], distillers dried grains with solubles (DDGS) [80], and coffee grounds [81]. However, the weak compatibility between the most of filler with PBAT (low polarity polymer) is one of the main problems, which can limit their broad application.…”

“…and to the subsequent reactions of these radicals with the environment. Especially for PBAT, the degradation can occur by two main routes: [77] enzymatically by bacteria, fungi, and algae that are present in the natural environment and/or no-enzymatic (e.g., thermal degradation, chemical hydrolysis) [108]. In the case of enzymatic degradation, aerobic bacteria, fungi, and algae readily act during biodegradation.…”

There is growing interest in biodegradable polymers (BP), in particular poly(butylene adipate‐co‐terephthalate) (PBAT), due to environmental problems associated with the disposal of non‐biodegradable polymers into the environment. However, high production cost and low thermo‐mechanical properties restrict the use of this sustainable material, making its biodegradability advantageous only when it is decisively required. The addition of different compositions of monomers and selective addition of natural fillers have been reported as alternatives to develop more accessible PBAT‐based bioplastics with performance that could match or even exceed that of the most widely used commodity plastics. This review explores the recent progress of the applications and biodegradation of PBAT. The addition of natural fillers and its effect on the final performance of the PBAT‐based composites is also reported with respect to improving the properties of composites. The advance of polymerization reaction engineering combined with sustainable trend offers great opportunities for innovative green chemical manufacturing. POLYM. ENG.

“…The authors in references [11][12][13][14] reported that the small peak that is related to the evaporation of water disappeared at high fiber contents. They attributed this disappearance to the improvement of the moisture absorption resistance of the composites with higher fiber contents.…”

“…Furthermore, the reinforcement of lignocellulosic fibers significantly improves the mechanical properties of starch-based matrix [10]. Sisal, jute, kenaf, coir, wood, pulp, cellulose, bagasse, banana, orange, and flax fibers are lignocellulosic fibers that have been all studied and found to substantiate enhancement for the starch-based matrix's versatile properties [10][11][12][13][14]. The objective of this article is to review and conduct further analysis to understand the effect of high-fiber content (flax, palm, banana, bagasse, bamboo, and hemp) on mechanical and physical properties.…”

Natural source-based composites became promising substitutes and synthetic petrochemical-based counterparts. So far, thermoplastic starch and lignocellulosic fibers are the most common materials for making such eco-friendly "green" materials. Low cost, abundance, and renewability are the factors that lead to deploying these two types of materials. In this chapter, we are conducting further analysis for previously published results of six types of high-content natural fiber-reinforced starch-based composites. All composites were prepared by compression molding under pressure from 5 to 20 MPa and temperature from 130 to 160°C. Composites exhibited highest tensile strength and modulus of elasticity at fiber weight content from 50 to 70%, and then mechanical properties deteriorated significantly at 80% fiber content due to the insufficient starch resin. For instance, the tensile strength was boosted up from 2-12 MPa for thermoplastic starch to reach 55,45,32,28,44, 365 MPa for flax, bagasse, date palm fiber (DPF), banana, bamboo, and hemp composites, when fiber content was increased from 0% to the optimum fiber content (50-70%). Kelly-Tyson (random 2d) was the optimum model to predict random fiber composite. Increasing the fiber content and choosing a fiber with high cellulose content significantly improve the moisture resistance of the composites. Fick's law of diffusion predicted the water uptake property successfully. The thermal stability of composites was improved with increasing the fiber weight content as well. This is attributed to the high thermal stability of cellulose when compared to starch. Properties exhibited by starch-based high-content natural fiber composite are promising for many industrial and biomedical applications.
