摘要
Electromagnetic (EM) pollution is evolving into a widely concerned environmental problem raised by the extensive application of EM emitting mobile devices. Microwave absorption materials (MAMs), as functional media for the sustainable conversion of EM energy, have been intensively developed for EM pollution precaution in the past two decades. Carbon materials are always considered as one of the most promising candidates for high-performance MAMs due to their tunable dielectric property, good chemical stability, low density, and diverse forms. In particular, carbon microspheres receive much considerable attention, not only for their intrinsic characteristics from the nature of carbon materials but also for their unique advantages in high dispersity and microstructure plasticity. Therefore, the construction of high-performance MAMs based on carbon microspheres has become an active field of research for microwave absorption. This perspective paper offers the recent advances on the explorations of various highly efficient MAMs related to carbon microspheres. Literature review indicates that some unique microstructures, including porous, hollow, core-shell, yolk-shell configurations, and rational chemical composition, can reinforce the microwave absorption performance of carbon microsphere composites significantly through intensifying their loss capability and improving their impedance matching. Besides, the challenges and perspectives are also proposed in terms of current research progress to inspire the further developments of carbon microspheres.
