Summary
Regardless of being a promising biodegradable materials, polylactic acid (PLA) nonetheless has a number of limitations primarily regarding its poor thermal resistance and brittleness. As well as, the excessive temperature throughout processing can result in the deformation of PLA and thus cut back its efficiency of PLA. To beat the above issues, L-Lactide functionalized cellulose nanocrystals enhanced PLA (PLA/CNC-g-PLA) have been efficiently ready by electrospinning expertise and the morphology, hydrophilic, thermal, and mechanical properties of the nanocomposite membranes with completely different ratios of CNC-g-PLA (1–10%) have been characterised. The outcomes demonstrated that the introduction of L-Lactide improved the interfacial compatibility between PLA and CNC. As well as, the mechanical properties and thermal stability of the composite fiber membranes have been enhanced by enhancing the molecular chain orientation by means of electrospinning. The tensile energy and elongation at break of the composite fiber movie elevated by 2.4 and eight.2 occasions, and T0 and Tmax elevated by 17 and 38 °C, respectively, when the addition of CNC-g-PLA was 5%. This promising nanocomposite with good properties is anticipated for use in tissue engineering and meals packaging functions.
