“…Transmission electron micrographs showing the differences in the microstructures of a graphitizing and a non-graphitizing carbon are presented in Figure 1 A and B, respectively. In a recent study on the microstructure of a nongraphitizing carbon by Sharma et al [28] the presence of ≈7% spherical fullerenes (mainly C 60 ) along with larger carbon fragments and stacked carbon layers in non-graphitizing carbons was confirmed via small-angle neutron scattering. This microstructural model proposed by the authors is shown in Figure 1C.…”

“…[27] In some cases, there are sheet-like structures formed from the beginning itself (e.g., during pyrolysis of poly vinyl chloride), while some polymers may convert into curved structures including fullerenes, due to the presence of a large amount of non-sixmembered rings. [28] Carbonaceous materials containing a high fraction of layers with plenty of hexagons can be converted into polycrystalline graphite when heated >2500 °C. These are called "graphitizing carbons".…”

Fabricating electronic devices from natural, renewable resources is a common goal in engineering and materials science. In this regard, carbon is of special significance due to its biocompatibility combined with electrical conductivity and electrochemical stability. In microelectronics, however, carbon's device application is often inhibited by tedious and expensive preparation processes and a lack of control over processing and material parameters. Laser‐assisted carbonization is emerging as a tool for the precise and selective synthesis of functional carbon‐based materials for flexible device applications. In contrast to conventional carbonization via in‐furnace pyrolysis, laser‐carbonization is induced photo‐thermally and occurs on the time‐scale of milliseconds. By careful selection of the precursors and process parameters, the properties of this so‐called laser‐patterned carbon (LP‐C) such as porosity, surface polarity, functional groups, degree of graphitization, charge‐carrier structure, etc. can be tuned. In this critical review, a common perspective is generated on laser‐carbonization in the context of general carbonization strategies, fundamentals of laser‐induced materials processing, and flexible electronic applications, like electrodes for sensors, electrocatalysts, energy storage, or antennas. An attempt is made to have equal emphasis on material processing and application aspects such that this emerging technology can be optimally positioned in the broader context of carbon‐based microfabrication.

Additive micro/nano‐manufacturing of polymeric precursors combining with a subsequent pyrolysis step enables the design‐controlled fabrication of micro/nano‐architected 3D pyrolytic carbon structures with complex architectural details. Pyrolysis results in a significant geometrical shrinkage of the pyrolytic carbon structure, leading to a structural dimension significantly smaller than the resolution limit of the involved additive manufacturing technology. Combining with the material properties of carbon and 3D architectures, architected 3D pyrolytic carbon exhibits exceptional properties, which are significantly superior to that of bulk carbon materials. This article presents a comprehensive review of the manufacturing processes of micro/nano‐architected pyrolytic carbon materials, their properties, and corresponding demonstrated applications. Acknowledging the “young” age of the field of micro/nano‐architected carbon, this article also addresses the current challenges and paints the future research directions of this field.
