| 摘 要： | 利用SEM、DMA和TGA研究双马来酰亚胺(BMI)/聚醚砜(PES)复相树脂微观相结构对热性能的影响。结果显示:BMI/PES复相树脂体系发生了相分离现象,当PES添加量达到15phr时,复相树脂体系中产生了相反转结构,富BMI颗粒相被富PES相紧密包裹;相比于纯BMI树脂,BMI/PES复相树脂中归属于富BMI相的玻璃化转变温度Tg升高;BMI/PES-5复相树脂中只有一个Tg,其起始模量降低对应的温度升高;随着PES添加量增大,BMI/PES复相树脂高温塑性行为更加明显;由于PES与BMI间良好的界面作用及富PES相的热防护作用,BMI/PES复相树脂的最大热失重温度和残炭率均得到显著增大;树脂体系在氮气氛围中的耐热性要优于空气氛围。
