“…All these fibers have the potential to be used as reinforcing and bonding materials for making polymer composites. Recently, due to growing environmental concerns, the demand for biodegradable materials derived from sustainable and renewable resources has attracted attention and has been utilized progressively. , Several researchers have reported the incorporation of organic materials as reinforcement for making polymer composites for structural and nonstructural applications. − Natural fibers have been used as one of the more sustainable sources to replace synthetic fibers in composites due to many advantages such as lower density, environmental friendliness, and renewability. − Sustainable agro-waste based polymeric composites are the amalgamation of polymer systems filled with agro-wastes, and have multi-functional applications. − Such composites are relatively low-cost, lightweight, recyclable, and environmentally friendly.…”

In this study, attempts were made for the first time to explore the unexploited wheat straw particulates (WSP) as a reinforcement filler with concentrations up to 100% in a thermoplastic polypropylene (PP) matrix to produce a new type of wood plastic composites. The WSP-PP composites were developed by melt blending using the injection molding technique and were investigated for their mechanical, structural, and thermal properties. The present study showed low-density composites with densities varying from 0.84–1.04 gm/cc. Compared to virgin polypropylene, WSP-PP composites showed enhanced impact strength, improved flexural strength and moduli, and lower water absorption. With increasing WSP concentration, the mechanical strength increases, and at 20–30% filler concentration, the composite showed a maximum tensile strength of 27.21 ± 0.67 MPa and flexural strength of 44.48 ± 0.48 MPa. The maximum impact strength of WSP-PP composites (2.04 ± 0.11 kJ/m2) was recorded at 40% filler concentration along with lower water absorption (1.67%). The addition of WSP was found to decrease the thermal conductivity of the WSP-PP composites. The findings of this study confirmed the scope of wheat straw as a potential cellulosic reinforcing filler for manufacturing a new class of green composites of high-performance characteristics which could be explored and beneficial for electrical applications, civil infrastructure, automotive parts, etc. Further, the utilization of this inexpensive raw material for the development of composites leads to a reduction in the practice of open straw burning in fields, thereby causing a decrease in CGH emissions. Thus, the realization of this innovative work will contribute to achieving the United Nations’ sustainable development goals with a sustainable approach toward building a circular economy.

This research explores the integration of corn husk nanocellulose (CHNc) and pineapple leaf nanocellulose (PLNc) as reinforcing agents in a carboxymethyl cellulose‐based film derived from durian husk (CMCDH). Through a solvent‐casting method, composite films were fabricated with varying nanocellulose contents (15, 30, and 45 wt%). Analysis using Fourier transform infrared spectroscopy and x‐ray diffraction confirmed the effectiveness of alkaline and bleaching treatments in eliminating noncellulosic components. Transmission electron microscopy image revealed the rod‐like morphology of CHNc and PLNc, with dimensions approximately 206.5 × 7.2 nm and 150.7 × 6.5 nm, respectively. The inclusion of nanocellulose decreased the transparency of CMCDH films while enhancing their tensile strength, thermal stability, and water vapor transmission rate. Notably, CMCDH/PLNc(30%) exhibited the highest tensile strength at 5.06 ± 0.83 MPa, representing a remarkable 220% increase compared to CMCDH biofilm. Thermogravimetric analysis and differential scanning calorimeter results indicated that nanocellulose incorporation delayed the film's decomposition temperature by approximately 10°C. Moreover, CMCDH/PLNc(30%) demonstrated the lowest water vapor transmission rate, marking a 20% improvement. However, the film's properties were compromised at the highest nanocellulose content (45 wt%) due to observed fiber aggregation, as revealed by scanning electron microscopy analysis.

A novel silane functionalization prepared by a solution mixing approach of epoxy composites filled with eco‐friendly reinforcement filler, that is, graphene oxide (GO) and microcrystalline cellulose (MCC). The developed composites were subjected to comprehensive analysis using various characterization techniques, encompassing mechanical testing, water absorption analysis, thermal stability assessment, and scanning electron microscopy (SEM). The tensile strength and Young's Modulus of the epoxy composite filled with 1.0 wt.% of GO (EGO1.0) demonstrated the highest value viz. 29.83 MPa and 1991.71 MPa, respectively, when compared to neat epoxy composite (E0). Meanwhile, the thermal gravimetry analysis (TGA) studies, particularly char yield, highlight improvements in the thermal stability of the EGO2.5 composite, that is, 23.39% representing a 33.73% increment compared to the E0 composite. The synergistic effect of hybrid filler, achieved by a combination of micro and nanoparticle fillers within an epoxy matrix, was investigated as a virtuous alternative to the conventional epoxy nanocomposites. A uniform dispersion of GO on the MCC surface leads to significant improvements in the mechanical properties and thermal stability of the epoxy‐reinforced composite. The maximum tensile strength, Young's Modulus, and break strain of 39.77 MPa, 2591.27 MPa, and 2.90%, respectively, were observed for the modified EGO1.0MCC1.5 composite. The synergistic effect of hybrid eco‐friendly reinforcement fillers (GO/MCC) and a strong interfacial adhesion between the matrix and filler reduces the formation of defects, thereby resulting in good stress transfer from matrix to fillers.
