“…The viscoelasticity, melting point, and thermal stability of preceramic polymers, the curing methods, ceramic yield, as well as thermal treatment methods are critical factors for the successful fabrication of high-performance ceramic fibers. During the last 50 years, numbers of ceramic fibers have been developed via PDC route, such as SiC(O) [212], Si-Ti-C-O [328], Si-Zr-C-O [328,329], SiCN [86], SiOC [87], SiBN [330,331], www.springer.com/journal/40145 SiBCN [74], SiBOC [302,332] fibers. The fracture surface of typical ceramic fibers, namely SiC fiber (Hi-Nicalon) and SiCN fiber (derived from polyorganosilazane named ABSE), is shown in Fig.…”

Since the 1960s, a new class of Si-based advanced ceramics called polymer-derived ceramics (PDCs) has been widely reported because of their unique capabilities to produce various ceramic materials (e.g., ceramic fibers, ceramic matrix composites, foams, films, and coatings) and their versatile applications. Particularly, due to their promising structural and functional properties for energy conversion and storage, the applications of PDCs in these fields have attracted much attention in recent years. This review highlights the recent progress in the PDC field with the focus on energy conversion and storage applications. Firstly, a brief introduction of the Si-based polymer-derived ceramics in terms of synthesis, processing, and microstructure characterization is provided, followed by a summary of PDCs used in energy conversion systems (mainly in gas turbine engines), including fundamentals and material issues, ceramic matrix composites, ceramic fibers, thermal and environmental barrier coatings, as well as high-temperature sensors. Subsequently, applications of PDCs in the field of energy storage are reviewed with a strong focus on anode materials for lithium and sodium ion batteries. The possible applications of the PDCs in Li-S batteries, supercapacitors, and fuel cells are discussed as well. Finally, a summary of the reported applications and perspectives for future research with PDCs are presented.

“…[46] If the relative humidity was kept at a high level, the excessive hydrolysis reactions happened and resulted in the formation of stripe-like flaws on the pyrolyzed fibers (Figure 3e). [42] Therefore, controlling the spinning process by selecting suitable temperature and humidity was one of the most effective ways to eliminate flaws. The control of the calcination process was another crucial point for the formation of flaw-free ceramic fibers.…”

Traditional ceramic materials are suboptimal for use in complex environments because of their brittleness and sensitivity to flaws. As such, developing flexible and elastic ceramic materials is extremely urgent in frontier domains where high-frequency vibration or high-intensity bending environments are inevitable. Fibrillation of ceramic materials is an effective way for the transition of brittleness to flexibility and elasticity, due to its ability to absorb and dissipate stresses through large axial deformations. Here, a comprehensive review of the newly emerging flexible and elastic ceramic fiber materials is presented, starting from an introduction to the fundamental concept, followed by an in-depth analysis of the relationship between their microstructures and mechanical behaviors, laying emphasis on the toughening mechanism of both individual fibers and fiber assemblies. Finally, current challenges and future development are demonstrated. It is expected that this review may provide meaningful guidance for the advancement of ceramic fiber materials toward better performance and brighter prospects.

“…For example, Cl 3 Si-NH-BCl 2 can crosslink into oligomers or polymers via polycondensation in NH 3 , and additional pyrolysis produces C-free SiBN ceramics, which have theoretical thermal stability up to 1700 • C. However, this type of precursor requires handling in a dry inert atmosphere due to hydrolysis reactions of the precursors with moisture. Liu et al studied the hydrolysis effect of polyborosilazane on SiBN ceramic fibers, demonstrating evidence of the formation of Si-O-Si groups in the precursor (Figure 5) [43]. The incorporated oxygen altered the surface features of pyrolyzed PDC fibers and caused the formation of β-SiO 2 at 1400 • C, leading to decreased thermal stability due to early crystallization.…”

High-Temperature Properties and Applications of Si-Based Polymer-Derived Ceramics: A Review

2021

View full text Add to dashboard Cite

Ceramics derived from organic polymer precursors, which have exceptional mechanical and chemical properties that are stable up to temperatures slightly below 2000 °C, are referred to as polymer-derived ceramics (PDCs). These molecularly designed amorphous ceramics have the same high mechanical and chemical properties as conventional powder-based ceramics, but they also demonstrate improved oxidation resistance and creep resistance and low pyrolysis temperature. Since the early 1970s, PDCs have attracted widespread attention due to their unique microstructures, and the benefits of polymeric precursors for advanced manufacturing techniques. Depending on various doping elements, molecular configurations, and microstructures, PDCs may also be beneficial for electrochemical applications at elevated temperatures that exceed the applicability of other materials. However, the microstructural evolution, or the conversion, segregation, and decomposition of amorphous nanodomain structures, decreases the reliability of PDC products at temperatures above 1400 °C. This review investigates structure-related properties of PDC products at elevated temperatures close to or higher than 1000 °C, including manufacturing production, and challenges of high-temperature PDCs. Analysis and future outlook of high-temperature structural and electrical applications, such as fibers, ceramic matrix composites (CMCs), microelectromechanical systems (MEMSs), and sensors, within high-temperature regimes are also discussed.
