| 摘 要： | 以十二烷基苯磺酸(DBSA)作为乳化剂和掺杂剂,通过乳液聚合的方法制备了DBSA掺杂聚苯胺/蒙脱土(PANI-DBSA/MMT)纳米复合物,并对其微波吸收特性进行了研究.通过X射线衍射(XRD)、傅立叶红外(FT-IR)和四探针测试仪对复合物进行了初步表征.结果表明,PANI-DBSA/MMT复合物中MMT层间距离明显扩大,纳米复合物中的PANI以emeraldine盐的形式存在,是一种典型的插层型纳米复合物.利用HP8722ES矢量网络分析仪测量了2 mm厚、PANI-DBSA/MMT含量为50 wt%的试样在2.0~18 GHz的复介电常数和复磁导率,经计算得到以反射损耗表示的微波吸收曲线,发现PANI-DBSA/MMT纳米复合物在9.1~12.5 GHz范围内反射损耗小于-10 dB,在11 GHz处存在的最大反射损耗为-15.8 dB. |

| Abstract: | The preparation and microwave-absorbing behavior of polyaniline-DBSA/montmorillonite(PANI-DBSA/MMT) nanocomposites were studied.The nanocomposite was synthesized by emulsion polymerization using dodecylbenzensulfonic acid(DBSA) as dopant and emulsifier.XRD,FT-IR and conductance measurements of the nanocomposite showed that the conductive emeraldine salt form of polyaniline was inserted into the layers of MMT to produce the nanocomposites with high conductivity.The complex permittivity and permeability of a 2.00 mm thick specimen containing 50% by weight of PANI-DBSA/MMT nanocomposite and PANI-DBSA were measured respectively in the range of 2～18 GHz,from which the reflection loss(RL) of microwaves was calculated and comparative absorption curves were given.The results shows that the PANI-DBSA/MMT nanocomposite is capable of absorbing 2.0～18 GHz microwaves,and the reflection loss is greater than-10 dB within the frequency range of 9.1～12.5 GHz,while the maximum reflection loss was-15.8 dB at 11 GHz. |
