摘      要：Sugar palm(Arenga pinnata)starch is considered an important renewable,biodegradable,and eco-friendly polymer,which is derived from agricultural by-products and residues,with great potential for the development of biocomposite *** research was aimed at investigating the development of TPS biocomposites from *** palm starch using an extrusion *** starch,glycerol,and stearic acid were extruded in a twin-screw *** electron microscopy(SEM)analysis of TPS showed that the starch granules were damaged and gelatinized in the extrusion *** density of TPS was 1.3695 g/mL,lower than that of palm starch,and the addition of stearic acid resulted in increased TPS density.X-ray diffraction(XRD)results showed that palm starch had a C-type pattern crystalline *** tensile strength,elongation at break,and modulus of elasticity of TPS were 7.19 MPa,33.95%,and 0.56 GPa,*** addition of stearic acid reduced the tensile strength,elongation at break and modulus of elasticity of *** rheological properties,i.e.,melt flow rate(MFR)and viscosity of TPS,were 7.13 g/10 min and 2482.19 Pa.s,*** presence of stearic acid in TPS resulted in increased MFR and decreased viscosity *** peak gelatinization temperature of *** palm starch was 70°C,while Tg of TPS was 65°*** addition of stearic acid reduced the Tg of *** thermogravimetric analysis(TGA)analysis showed that the addition of glycerol and stearic acid decreased the thermal stability,but extended the temperature range of thermal *** derived from *** palm starch by extrusion method has the potential to be applied in industrial practice as a promising raw material for manufacturing bio-based packaging as a sustainable and green alternative to petroleum-based plastics.
