| 摘 要： | 以纳米聚苯胺为电磁波的吸收剂,高强度、耐高温的聚酰亚胺为基体设计与制备了高强度、耐热、质轻、薄和吸收宽的新型纳米复合吸波材料.利用微乳液法,以十二烷基苯磺酸(DBSA)为乳化剂和掺杂剂,以过硫酸铵(APS)为氧化剂合成了纳米级聚苯胺(PANI).在此基础上,以PANI的NMP溶液为均苯四甲酸二酐(PMDA)与4,4′-二氨基二苯醚(ODA)的聚合场所,室温下,原位聚合出PANI/聚酰胺酸(PAA)复合材料,再经过亚胺化制备出了PANI/PI复合材料.利用XRD表征了聚合物的结晶形态.红外光谱表征了中间体和聚合物.利用场发射扫描电镜发现PANI/PI复合材料呈现海岛结构,PANI像岛屿一样分散在PI的连续相中,两种材料复合并没有破坏各自的结晶形态.利用数字电桥和自制电极表征了不同含量复合材料的损耗性能,当聚苯胺加到3.4%以上时,复合材料的损耗因数提高了,并且随着频率的增大损耗因数直线增大.

| Abstract: | Polyimide(PI)/polyaniline(PANI) nanocomposites were prepared as a electromagnetic wave absorption material. Nano-PANI was synthesized with DBSA as the emulsifier and doping agent and APS as oxidant by a micro-emulsion method. On this basis,PAA/PANI composites were synthesized in NMP saturated solutions of PANI at room temperature,then PI/PANI composites were prepared through imidization.The crystallization of polymers was characterized by XRD,the intermediate and polymer were also characterized by FTIR spec... |
