- The crosshead speed was 50 mm/min. All measurements were repeated five times on bone-shaped specimens (ASTM D638) and averaged to obtain the final result.
- X-ray diffraction (XRD) studies were conducted on a Rigaku D/max 2200H X-ray diffractometer (40 kV, 50 mA) with a scanning rate of 2°/min. In order to study the morphology of the samples, cross sections of the blends were cryogenically fractured and examined using a field-emission scanning electron microscope (FE-SEM, HITACHI S-4200, Japan).
- However, there have been relatively few studies on the effects of a compatibilizer on the mechanical properties of LDPE/CTPS and LDPE/CS blends. In this work, the effects of a compatibilizer (PE-g-MAH) on the mechanical properties of LDPE/TPS, LDPE/CS, and LDPE/CTPS blends were investigated.
- Before melt-blending, all materials were pre-dried at 40℃ for 4 h within a vacuum oven. The LDPE was then mixed with varying quantities (5, 15, and 30 wt%) of modified starch (CS, TPS, and CTPS) with or without PE-g-MAH (5 wt%) at 100 rpm and 140℃ for 10 min in a Hakke internal mixer with the temperature and torque being monitored during the mixing process. The obtained bulk specimens were compression-molded in order to fabricate sheets under the following conditions: 150℃ for 5 min at a pressure of 150 bar, followed by treatment with a cooling press at room temperature at a pressure of 100 bar in order to fix the shape of sheets.
