A study on the thermomechanical properties of surface functionalized Alumina filled polybutylene Succinate composites |
| 초록 |
Poly-Butylene Succinate (PBS) is a biodegradable polymer which is expected to have a wide range of application due to the recent shift towards environmentally friendly products. This study investigates the effect of the incorporation of alumina particles on the thermomechanical properties of PBS/Al2O3 composites. The alumina surface was modified with the carboxylic groups of maleic acid through simple acid-base and in situ polymerization reactions. Scanning electron microscope (SEM) results showed the introduction of maleic acid significantly affect the morphology of the PBS/Al2O3 composites as compared to the neat PBS. In particular, the thermal conductivity of the composite (0.411 W m-1 K-1) was more than twice that of neat PBS. In addition, universal testing machine (UTM) and differential scanning calorimetry (DSC) measurements indicated an increase in the tensile strength and degree of crystallinity after the incorporation of modified alumina in the PBS/Al2O3 composite. The composite containing polymerization-modified alumina showed a 50% increase in storage modulus compared with that of pristine PBS. |
