POSS/PS复合材料的结构与燃烧性能
he structure and combustion properties of POSS/PS composites
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%。
Ionic Polyhedral Oligomeric Silsesquioxane (POSS)/Polystyrene (PS) composites were prepared by 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 CO2 by 23.8% and 53.1%, the concentrations of CO by 31.1% and 62.0% respectively in the Cone Calorimetry test.
