中文摘要：

采用溶胶-凝胶（Sol—Gel）法制备了PET／SiO2纳米复合材料。用基于耗氧原理的锥形量热仪，测试并分析PET／SiO2纳米复合材料的阻燃性能。结果表明，PET／SiO2纳米复合材料的热释放速率及其峰值、总释热量与纯PET相比均明显降低。

英文摘要：

Polv（ethvlene terephthalate） （PET）/SiO2 nanoeomposites were synthesized via the Sol-Gel method. The flammability of nanocomposites were determined by CONE. The results indicated that the HRR, pHRR and THR of PET/ SiO2 nanocomposites were all lower than those of pure PET.
