N2 - A study was conducted to investigate the effect of lysine triisocynate (LTI) on the mode I fracture behavior of polymer blend of poly(L-lactic acid) (PLLA) and poly(butylene succinate-co-L-lactate) (PBSL). Pelletized PLLA and PBSL were blended using a conventional melt-mixer at 190°C and a rotor speed of 50 rpm for 20 minutes. The mode I fracture tests of the SENB specimens were carried out at a loading rate of 1 mm/min using a servohydraulic testing machine. The high resolution field emission scanning electron microscope (FE-SEM) was used to determine the microstructures of the blends. It was observed that mode I fracture properties of PLLA/PBSL polymer blends improved significantly by the addition of LTI. Addition of LTI into PLLA/PBSL caused an improvement in the immiscibility between PLLA and PBSL, which further caused suppression spherulite formation of PBSL.
