Synthesis and Characterization of a New Mesoporous Carbon-Containing Electromagnetic Wave Absorber

The development of an ideal electromagnetic (EM) wave absorber with the ability to absorb the entire incident wave is an important issue in preparing an efficient photoelectric conversion device using a mesoporous-based absorber. Reflectance and absorption are intrinsic properties of materials that are strongly associated with the refractive index. To tune the absorption frequency spectrum, we developed a polymer matrix-based nano-absorber-based transparent tunable absorber. By doping Ni4FeCr/Mc with polypyrrole (PPy), we experimentally show an increase in reflectance loss (RL) to evaluate the mesoporous capture, PPy conductivity, and the performance of the absorber for the composite material of the absorber. PPy, present locally within the mesoporous carbon (MC) lattice, connects the intracellular skeleton to the surrounding extracellular matrix. This study has shown that impedance matching was highly dependent on PPy-doped samples. Because this method is very simple, cost-effective for large-area fabrication, and is compatible with current industrial methods of micro-electromechanical systems, it is an excellent candidate for advanced high-efficiency absorbing materials.
