| 摘 要： | 以离子型八（四甲基铵）笼形倍半硅氧烷（OctaTMA_POSS）作为聚苯乙烯（PS）的添加剂制备POSS／PS复合材料．结果表明；20％和30％的POSS添加量可使其在PS中形成纳米纤维并呈网状分布，使复合材料的热释放速率峰值分别降低31.7％和54．6％，CO释放速率峰值分别降低55．3％和66．1％，CO浓度峰值降低66．2％和70．8％，CO2释放速率峰值分别23．8%和53．1％，CO2浓度峰值降低31．1％和62．0％．

| Abstract: | Ionic Polyhedral Oligomeric Silsesquioxane(POSS)/Polystyrene(PS) composites were prepared with the melt-mixing method,using Octa(tetramethylammonium) POSS as an addictive.Formation of nanofibres and netlike dispersion in PS can be achieved with a POSS content of up to 20% and 30%,which can reduce the peak Heat Release Rate(HRR) by 31.7% and 54.6%,the release rates of CO by 55.3% and 66.1%,the concentrations of CO by 66.2% and 70.8%,the release rates of CO_(2) by 23.8% and 53.1%,the concentrations of CO by 31.1% and 62.0% respectively in the Cone Calorimetry test. |
