Preparation, Characterization, and Electrical Properties of ZSM-5/PEG Composite Particles

ZSM-5/PEG composites were synthesized by a simple solution method with polyethylene glycol (PEG) and H-ZSM-5 zeolite (Si/Al=11.4). The obtained composites were characterized using X-ray powder diffraction and Fourier transform infrared spectroscopy. The obtained results indicated that the ZSM-5 was physically combined with PEG. The thermal properties and thermal stability were investigated by thermogravimetric and differential thermal analyses. In situ electrical conductivity was used to follow-up the changes in the electrical conductance during the heating of the ZSM-5/PEG composite. It was found that ZSM-5 is able to effectively enhance the electrical conductivity of PEG. The results showed that the obtained weight loss during the composite decomposition to charcoal is accompanied by a decrease in the electrical conductivity. Moreover, the removal of the formed charcoal is associated with an electrical conductivity increase. Calcining the ZSM-5/PEG composite having a content of 30% results in many effects on the structural, textural, and electrical properties of the obtained products. POLYM. COMPOS., 35:1160-1168, 2014.
