Large reflection loss (RL) and broad effective bandwidth (Δf10) are two of the most important parameters for microwave-absorbing materials (MAMs). In this article, we report that a strong and broad microwave absorption can be obtained with poly(3,4-ethylenedioxythiophene) (PEDOT), with record-setting values over previous studies. These record-setting values are derived using a data-driven method to optimize the response parameters. We demonstrate that RL values are achieved of −54.0 dB centering 8.3 GHz with 3.4 mm thick 30.0 wt % PEDOT film and −42.6 dB centering 17.0 GHz with 1.5 mm film for 40.0 wt % PEDOT; Δf10 values of 5.8 and 5.2 GHz are shown with a film thickness of 2.1 and 1.7 mm, respectively.

用数据驱动方法实现聚(3,4-乙撑二氧噻吩)的最大微波吸收

大的反射损耗(RL)和宽的有效带宽(Δf 10)是微波吸收材料(MAM)的两个最重要的参数。在本文中,我们报告说,使用聚(3,4-乙撑二氧噻吩)(PEDOT)可以获得强大而广泛的微波吸收,其设置值超过了以往的研究。这些记录设置值是使用数据驱动的方法导出的,以优化响应参数。我们证明,对于3.4 mm厚的30.0 wt%PEDOT薄膜,以8.3 GHz为中心的-54.0 dB的RL值,对于40.0 wt%的PEDOT用1.5 mm薄膜为中心的17.0 GHz的-42.6 dB的RL值;Δ ˚F 10个的5.8值和5.2千兆赫中分别示出为2.1和1.7毫米的膜厚度。
