Morphology and thermal properties of poly(l-lactic acid) nucleated with 2,2'-(butane-1,4-diylbis(oxy))di(benzohydrazide).

ABSTRACT: This study evaluates the modification of biodegradable poly(l-lactide) (PLLA) using a novel organic nucleating agent, 2,2'-(butane-1,4-diylbis(oxy))di(benzohydrazide) (BDOBH) with a low concentration range from (0.3-3 wt%). The novelty of this work lies in the development and application of BDOBH as a highly efficient, low-loading organic nucleator tailored to improve PLLA's crystallization behavior and thermal properties-key limitations in its broader industrial use. The evaluation is conducted through differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), and polarized optical microscopy. FTIR analysis reveals the presence of H-bonding interaction between BDOBH and PLLA. DSC results significantly improve PLLA's crystalli
