Natural fibre and biopolymer based biocomposites are getting rising consideration owing to their renewability and biodegradation properties. In order to observe the behavior of these biocomposites in outdoor applications, its environmental reaction properties such as soil biodegradation need to be analyzed. In this study coir fibres (CF) and pineapple leaf fibres (PALF) reinforced polylactic acid (PLA) hybrid biocomposites (CF/PALF/PLA), pure PLA, pure CF (C30) and PALF (P30) biocomposites were fabricated through heat compounding and hot pressing methods. Effect of soil biodegradation on the tensile properties of PLA, CF and PALF biocomposites, and hybrid biocomposites were assessed and evaluated by Soil Burial tests. Tensile samples of all biocomposites undergoes soil burial test for 60 and 90 days at natural condition. After the subjected period, the results indicated that there is reduction in weight, tensile strength and modulus values of biocomposites owing to lignin degradation and fibre–matrix bonds

Mediated Oxidation

Poly (lactic acid) or PLA was reinforced by nanocellulose and polyethylene glycol (PEG), which were introduced into PLA matrix from 0 to 3 wt.% to enhance compatibility and strength of the PLA. The nanocellulose was prepared by TEMPO-mediated oxidation from microcrystalline cellulose (MCC) powder and characterized by TEM, AFM, and XRD to reveal rod-like shaped nanocellulose with nanosized dimensions, high aspect ratio and high crystallinity. Films of nanocellulose/PEG/PLA nanocomposites were prepared by solvent casting method to evaluate the mechanical performance. It was found that the addition of PEG in nanocellulose-containing PLA films resulted in an increase in tensile modulus with only 1 wt% of PEG, where higher PEG concentrations negatively impacted the tensile strength. Furthermore, the tensile strength and modulus of nanocellulose/PEG/PLA nanocomposites were higher than the PLA/PEG composites due to the existence of nanocellulose chains. Visual traces of crazing were detailed to describe the deformation mechanism.
