摘要
The star macromolecules (SM) were synthesized from phloroglucinol, phosphorus oxychloride, and poly(ethylene glycol methyl ether) with different molecular weight. Structures of the products were characterized by Fourier transform infrared and 1H-nuclear magnetic resonance. Solid polymer electrolyte films were prepared by mixing the products with poly(ethylene oxide) (PEO) and LiClO4. The polymer blends of PEO and SM have been characterized by differential scanning calorimetry and thermogravimetry, and the polymer electrolytes have been characterized by alternating current impedance. All the SM products could improve the conductivities of the polymer electrolyte obviously at a temperature range from 20 °C to 80 °C.
