摘要
采用乳液聚合制备的掺杂态聚苯胺(PAn-DBSA)与三元乙丙共聚物(EPDM)进行熔融混炼,热压成不同厚度的共混物(PAn-DBSA/EPDM)吸波贴片。在雷达波频段(S、C、X、Ku,2—18GHz)测试结果表明,不同掺杂态聚苯胺(PAn-DBSA)含量(wt%)、贴片厚度(mm)与加工工艺条件(混练时间、混炼温度)和聚苯胺形貌特征对共混物(PAn-DBSA/EPDM)的吸波性能有明显影响,并呈现宽频吸波效应(X频段,8-12GHz)。
Blends of ethylene-propylene-diene monomer(EPDM)and polyaniline(PAn)doped with dodecyl- benzene sulfonic acid(DBSA)by emulsion polymerization were prepared by mechanical mixing and calendering at various compositions and sheet depth.Through designing single and multilayer sheets of PAn-DBSA/EPDM blends,the reflec- tivity characteristics of the blends in 2-18GHz range were investigated with NRL method.The microwave behavior was affected by the concentration of PAn-DBSA within the EPDM matrix and sheet depth ...
