Summary: Flexible polymer composite films comprising methyl cellulose (MC), polyaniline (PANI), and silver nanoparticles (AgNPs) were successfully fabricated through a cast preparation method. The inclusion of AgNPs and PANI enhanced the optical properties of the MC polymer, providing a new composite suitable for energy conversion systems, solar cells, biosensors, and nonlinear optical applications. The band gap of MC/PANI/AgNPs decreased compared to the pure MC film, while the carbon cluster number increased with the incorporation of AgNPs.

Summary: The electromagnetic parameters and absorbing properties of Fe3O4/corn straw core (F/C) composite were modified by changing the molar concentration of iron source. The F/C material maintained the initial three-dimensional pore structure of the straw core, with a high specific surface area of 26.45 m(2)/g and Fe3O4 particles loaded inside and outside the pore. At a thickness of 3.5 mm, the minimum reflection loss of the composite reached -30.03 dB and the effective absorption bandwidth was 4.17 GHz (7.54-11.71 GHz). The material's absorption loss is mainly due to the synergistic effect of dielectric loss, polarization relaxation, and magnetic loss. The wave absorbing material has great potential in promoting the high value and functional utilization of biological waste.
