“…[1][2][3] While previous efforts have focused primarily on the development and characterization of biomorphic silicon carbide from wood, [4][5][6][7][8][9][10] biomorphic graphitic scaffolds are of particular interest due to the attractiveness of porous graphite for use in thermal management devices. 11,12 Graphitic scaffolds combine low density, low thermal expansion coefficient, and high thermal conductivity, making them ideal candidates for many thermal management applications.…”

A catalytic technique to enhance graphite formation in nongraphitizing carbons was adapted to work with three-dimensional wood-derived scaffolds. Unlike many synthetic graphite precursors, wood and other cellulosic carbons remain largely disordered after high temperature pyrolysis. Using a nickel nitrate liquid catalyst and controlled pyrolysis conditions, wood-derived scaffolds were produced showing similar graphitic content to traditional pitch-based graphite while retaining the high-aspect ratio pores of the precursor wood microstructure. Graphite formation was studied as a function of processing time and pyrolysis temperature, and the resulting carbons were analyzed using x-ray diffraction, Raman spectroscopy, x-ray photoelectron spectroscopy, and electron microscopy techniques.

“…Subsequently, the reinforcement phases were infiltrated with nickel matrices by room temperature electrodeposition (Fig. 1C), which efficiently avoided obstacles associated with the most commonly applied high-temperature melt infiltration of metal matrices, such as residual stresses stemming from expansion mismatch between reinforcement and matrix ( 34 , 35 ). During deposition, the electrical conductivity of the pyrolytic carbon was exploited to initiate growth of the metal phase directly on the reinforcement surfaces.…”

Architected metals and ceramics with nanoscale cellular designs, e.g., nanolattices, are currently subject of extensive investigation. By harnessing extreme material size effects, nanolattices demonstrated classically inaccessible properties at low density, with exceptional potential for superior lightweight materials. This study expands the concept of nanoarchitecture to dense metal/ceramic composites, presenting co-continuous architectures of three-dimensional printed pyrolytic carbon shell reinforcements and electrodeposited nickel matrices. We demonstrate ductile compressive deformability with elongated ultrahigh strength plateaus, resulting in an extremely high combination of compressive strength and strain energy absorption. Simultaneously, property-to-weight ratios outperform those of lightweight nanolattices. Superior to cellular nanoarchitectures, interpenetrating nanocomposites may combine multiple size-dependent characteristics, whether mechanical or functional, which are radically antagonistic in existing materials. This provides a pathway toward previously unobtainable multifunctionality, extending far beyond lightweight structure applications.

In one approach, one selects the main microstructural features responsible for improved properties a designs processes to obtain materials with such microstructures (continuous-fiber-reinforced ceramics, porous ceramics, fibrous ceramic monoliths, etc.). In a different approach, it is possible to use natural materials directly as microstructural templates. Biomorphic ceramics are produced from natural and renewable resources (wood or wood-derived products). A wide variety of SiC based ceramics can be fabricated by infiltration of silicon or silicon alloys into cellulose-derived carbonaceous templates, providing a low-cost route to advanced ceramic materials with near-net shape potential and amenable to rapid prototyping. These materials have tailorable microstructure and properties, and behave like ceramic materials manufactured by advanced ceramic processing approaches. This review aims to be a comprehensive description of the development of bioSiC ceramics:from wood templates and their microstructure to potential applications of bioSiC materials.
