摘要

将本征态聚苯胺的N-甲基吡咯烷酮溶液浇铸在玻璃基板上

烘干脱去基板后得到自支持本征态聚苯胺薄膜

用HCl气体对薄膜进行掺杂

通过控制掺杂时间来控制掺杂浓度。红外反射率测试结果表明:在大气窗口内

掺杂浓度较低时

薄膜的红外反射率随着掺杂浓度的提高而增加;到达一定掺杂浓度后

反射率会随着掺杂浓度的提高有所降低

最终趋于稳定。其中

3~5 m波段的最高反射率为53.1%

8~14 m波段的最高反射率为57.6%

两个波段内达到最大反射率时的掺杂程度不相同。膜厚引起的干涉作用对红外反射性能也有一定影响。在所研究的掺杂范围内

聚苯胺薄膜对微波的透射性能良好

在某些波段对微波还有一定的吸收作用。

Abstract

Polyaniline (emeraldine base

EB) powder was dissolved in n-methylpyrrolidone (NMP). Then the NMP solution of EB was cast on glass substrate and dried under a vacuum to obtain the EB film. The EB film was doped by exposing them in the atmosphere of hydrogen chloride volatilized by hydrochloric acid. The doped degree was controlled by the concentration of hydrochloric acid solution and different time that the film was exposed in HCl gas. The results show that

in the beginning

the infrared reflectivity of the film in the atmospheric window increases with the doped degree increases. Then the infrared reflectivity begins to decrease after the doped degree come to a certain degree. At last

the value of infrared reflectivity keep steady. The highest reflectivity in the wave range of 3~5 m is 53.1%

and the highest reflectivity in the wave range of 8~14 m is 57.6%. The doped degree when the highest reflectivity appears in different wave range is diffe-rent. The interference comes from the thickness of the film also influences the reflectivity in some narrow wave range. Due to the simpleness of the doped method

it is easy to realize the camouflage with thermal colors. The microwave absorption property of the EB film with different doped degree was also investigated. In general

all EB films with different doped degree show the excellent transmittance. In some wave range

the EB film with proper doped degree can also absorb the microwave. It can be used as a part of stealthy composite material to cover the targets on the ground.
