【 摘 要 】

Poly(ethylene) glycol (PEG)/ZrSiO4 composites have been prepared and their thermomechanical propertis have been characterized using a dynamic mechanical analyzer (DMA). PEG 4000 was used as the matrix and a ZrSiO4 powder, extracted from puya sand Kereng Pangi, Central Kalimantan, was used as the filler. ZrSiO4 weight fractions of 0, 5, 10 and 20% were employed. The composites were made by a liquid method, where the matrix and the filler were mixed at a temperature when PEG was in a liquid phase. Characterization of FTIR and XRD was used to confirm the absence of any new phase and the composites were formed. The composites were subjected to DMA measurement in a shear mode at a frequency of 1 Hz. Results showed that, in general, the storage modulus of the composites has been improved by the addition of ZrSiO4. The highest storage modulus was achieved by the composite with 20% ZrSiO4, i.e., nine times of the pure PEG. The 20% ZrSiO4 composite also exhibited the largest damping factor (the widest width of tan δ peak) and the highest melting temperature (Tm ), i.e., 57.1 °C, increasing 14.1 °C from that of pure PEG.
