“…Further research on the use of biopolymer blends for packaging material showed poor mechanical properties. Biopolymers such as polylactic acid, chitosan, cellulose have been reported to have low mechanical properties [ 6 ]. This has discouraged their use for many applications such as automobile parts and aerospace.…”

The degradation and mechanical properties of potential polymeric materials used for green manufacturing are significant determinants. In this study, cellulose nanofibre was prepared from Schizostachyum brachycladum bamboo and used as reinforcement in the PLA/chitosan matrix using melt extrusion and compression moulding method. The cellulose nanofibre(CNF) was isolated using supercritical carbon dioxide and high-pressure homogenisation. The isolated CNF was characterised with transmission electron microscopy (TEM), FT-IR, zeta potential and particle size analysis. The mechanical, physical, and degradation properties of the resulting biocomposite were studied with moisture content, density, thickness swelling, tensile, flexural, scanning electron microscopy, thermogravimetry, and biodegradability analysis. The TEM, FT-IR, and particle size results showed successful isolation of cellulose nanofibre using this method. The result showed that the physical, mechanical, and degradation properties of PLA/chitosan/CNF biocomposite were significantly enhanced with cellulose nanofibre. The density, thickness swelling, and moisture content increased with the addition of CNF. Also, tensile strength and modulus; flexural strength and modulus increased; while the elongation reduced. The carbon residue from the thermal degradation and the glass transition temperature of the PLA/chitosan/CNF biocomposite was observed to increase with the addition of CNF. The result showed that the biocomposite has potential for green and sustainable industrial application.

“…PLA and CNF are having the challenge of agglomeration, which has resulted in low mechanical properties of its composite film. The amphiphilic properties of chitosan were used as a compatibilizer between PLA and CNF in this study 28,36 . In this study, amphiphilic chitosan was prepared and used to enhance polylactic acid's miscibility and properties between PLA and cellulose nanofiber.…”

The blending of hydrophilic materials with hydrophobic polymers has been reported with agglomeration due to their functional group immiscibility properties. In this study, the properties of PLA/CNF biocomposite were enhanced with amphiphilic chitosan produced by a substitution reaction. The substitution reaction was studied with FT‐IR analysis. The amphiphilic chitosan was used as part of the matrix PLA/chitosan and reinforced with CNF to obtain PLA/chitosan/CNF biocomposite using combined melt extrusion and compression molding technique. The morphology and structural bonding of amphiphilic chitosan added in the biocomposite were studied with SEM, XRD, and FT‐IR. Furthermore, the mechanical, thermal, and wettability properties of PLA/chitosan/CNF composite were studied with tensile analysis, thermogravimetry analysis, differential scanning calorimetry, water absorption, thickness swelling, and contact angle test. The preparation of the amphiphilic chitosan was successful, as observed from the FT‐IR functional group analysis. The PLA/chitosan/CNF biocomposite properties showed a significant enhancement in the miscibility, mechanical, and thermal properties with no agglomeration. The wettability test also showed that the composite has a reduced hydrophobic nature compared with the neat PLA. The PLA/chitosan/CNF properties showed potential use for packaging application.
