A simple one step organic to inorganic pyrolysis route to bulk quantity boron carbonitride/carbon nanocables

Porous-carbon-nanotube decorated carbon nanofibers with effective microwave absorption properties

“…The high EM absorption can be achieved by a magnetic particle incorporated in the composite, but the high specific mass caused by magnetic additives generates serious weaknesses in heavy stealth equipment. Carbon materials, including CNFs [14,16], porous carbon fiber [12] and CNTs [13] have played a leading role in the research and application of EM absorbers because of their low density and low cost. Among these carbon materials, CNFs and CNTs have excited great interest due to their high aspect ratio, which benefits high EM absorption of the composite at low filler content and light weight.…”

“…Graphene/stainless steel web hybrids have achieved a minimum reflection loss of −42.6 dB at 8.5 GHz [15]. Boron carbonitride/carbon nanocables have exhibited a minimum reflection loss of −24.5 dB at 14.48 GHz [16]. Despite a great deal of research on carbon-based materials for EM-wave absorption, some scientific requirements still exist for new generationEM-wave absorbers: light weight (or low density), broad bandwidth, strong EM-wave absorption, tunable absorption frequency and mechanical functionality.…”

A new precursor to diversify BCN architectures with enhanced electromagnetic wave absorption

“…The pyrolysis method refers to a method in which a substance decomposes and reacts by thermal decomposition. The advantage is that the cost is relatively low, the experimental process is relatively simple, and a compound the microstructure can be adjusted by adjusting the parameters of the precursor during the preparation process, so the relative advantages of the precursor pyrolysis method are increasingly obvious [24][25][26][27]. Zhang et al [27] reported a one-step thermal decomposition method at 1100 °C using organic compounds and successfully synthesized a large number of BCN/C nanomaterials, which are expected to be used in industrial production.…”

CVD is a synthesis method that directly uses gaseous raw materials or vaporizes the raw materials at high temperature to react and deposit on the substrate to prepare the target product.…”
