“…[6,7] In addition to the possibility to introduce and control pore architectures, the PCP approach facilitates a straightforward way to introduce functional features by in situ formation, such as metal nanoparticles [8] or percolating carbon networks, [9] or by integration with 2D materials. [10] The introduction of mesoporosity into PDCs has been of particular recent interest for prospective applications in clean energy technologies. [11] Here, self-assembly techniques have become an important pathway toward nanostructuring non-oxide PCP-derived ceramic materials, with suitable structure-directing agents such as block copolymers facilitating mesoporous structures with lamellar, cylindrical, or gyroidal morphology.…”

Additive manufacturing techniques such as vat photopolymerization have laid the foundation for impressive advances in the 3D structuring of ceramic materials. However, simultaneous structuring of these complex‐shaped ceramic objects on the sub‐µm scale, an essential feature for a wide range of applications in separation, energy conversion and storage, adsorption or sensing, has remained a tremendous challenge. This study demonstrates how complex‐shaped polymer‐derived SiOC ceramics exhibiting hierarchical porosity ranging from the sub‐µm‐ to the millimeter‐range can be generated by combining vat photopolymerization with photopolymerization‐induced phase separation using preceramic polymer‐based phase‐separating resins. In addition to allowing single‐step, multi‐level structural control, this new processing concept allows for the chemical modification of the 3D‐printable, phase‐separating preceramic polymer resins using organometallic compounds, including the possibility to generate functional metal nanoparticles in situ during the polymer‐to‐ceramic conversion. In this manner, a chemical toolbox is provided, facilitating the introduction of Ni, Co, Mo, or La into the hierarchically structured SiOC matrix. The versatile applicability of this new materials design approach is demonstrated by employing complex‐shaped, hierarchically porous monoliths containing in situ generated Ni nanoparticles as heterogeneous catalysts for CO2 methanation, with a profound increase in catalyst performance attained by oxidative post‐treatment of the metal‐ceramic hybrid material.

“…These material-diverse precursors are simple to work with, can be directly shaped, and their flow properties can be tuned according to specific processing methods, including electrospinning, fiber pulling, injection and extrusion molding, casting, and three-dimensional (3D) printing. [1], [2] Depending on the material type, processing of these precursors follow different routes. In the case of polymers and polymer composites, the final product is obtained following the solidification of the polymer matrix.…”

Considering their simplicity, processibility, and tunable rheological properties, polymer composite-type precursors hold exceptional promise in the processing of polymers, ceramics, metals, and their composites. This large variety of precursors used in many different applications cover a large compositional space with dramatically varying rheological properties. Understanding how precursor composition influences their rheological properties is a key need towards streamlining the design and implementation of these precursors. With regard to this design advancement, this study elucidates the composition-rheology relationships of graphene-poly(ethylene) oxide (PEO) composite inks as a sample polymer composite-type precursor. To this end, shear and extensional rheology of numerous compositions were studied across a wide compositional space, which varied graphene concentration, total solid concentration, and binder molecular weight. These studies showed that composition greatly affected various rheological parameters, such as the overall presence of yielding behavior. Specifically, this study illustrated the influence of (i) binder structure, (ii) total solid loading, and (iii) binder-filler interactions on ink rheology. Extensional rheology was studied to examine how relaxation behaviors were dependent on composition and explicate how relaxation behaviors coincide with responses to shear forces. In tandem, our results illuminate significant composition-rheology relationships in polymer composite-type precursors.
