Summary
Nowadays, superfluous microwave radiation has become one typical contamination, which brings about a great deal of menace to human health. In order to deal with such serious electromagnetic pollution generated from the wide application of electromagnetic equipment and microwave technique, there is an urgent requirement to manufacture an absorber with excellent electromagnetic absorption performance. Usually, the demand for an ideal absorber should satisfy the properties of strong absorption ability, broad absorption bandwidth, thin thickness and low density. Apart from these, the facile route to prepare the as-mentioned absorber with environmental protection and economy is also paid great attention by many scholars. In recent years, renewable biomass has been employed to fabricate biochar with multifarious nanostructures for being used as one of the effective absorbing components in microwave absorbing composites for their advantages, and thus they are often combined with other magnetic components to achieve significant performance for synergetic mechanisms and improved condition of impedance matching etc.
This special issue is dedicated to insights into the design and preparation of microwave absorbing composites based on a combination of renewable biomass and various magnetic materials for eliminating radiation contamination. We invite scientists and investigators to contribute original high-quality research and review articles which address the topics of this special issue. Topics of interest include but are not limited to:
· Novel methods to prepare bio-based magnetic microwave absorbing composites;
· Regulation of microstructure in renewable biomass-derived magnetic absorbers;
· Optimization of electromagnetic properties in bio-based magnetic composites;
· Biomass-based magnetic composites for eliminating radiation contamination.
· The new-type absorbing mechanism in bio-based magnetic substance.
Please note that the above topics are recommended and by no means exclusive. Studies on other research areas of this special issue are also welcomed.
