“…Several methods have been developed to prepare CMCs using 2D/3D fiber preforms and ceramic precursors, such as chemical vapor infiltration (CVI), polymer infiltration and pyrolysis (PIP), slurry infiltration (SI), reactive melt infiltration (RMI), or liquid silicon infiltration (LSI), as well as the hybrid of these methods [82,106,298,299]. Preceramic polymers have been used for the fabrication of CMCs in two different aspects: (1) producing ceramic fibers as reinforcement (will be discussed later) [6,150,[300][301][302][303]; (2) producing the ceramic matrix via PIP process [16,17,297,304]. The procedures of PIP processing to fabricate polymer-derived CMCs are 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.

“…The ceramic matrix may react with the interphase coating/fiber during the repeated PIP process, which can deteriorate the strength of fiber reinforcement as well. In addition, the pyrolysis temperature should be carefully chosen to ensure that the reinforcing fibers do not lose its strength [297,327].…”

“…Poly(vinyl alcohol) (99%, Mw 89,000-98,000, Sigma Aldrich) was used as a binder to realise the ceramic fiber preform. MVBS, the precursor for SiBOC, was synthesised in-house from analytical reagent grade triethoxy(vinyl)silane (C 8 H 18 O 3 Si, assay ≥ 97%, Evonik Industries, Germany), triethoxy(methyl)silane (C 7 H 18 O 3 Si, assay ≥ 99%, Sigma-Aldrich Chemie GmbH, Germany) and boric acid (assay ≥ 99.5%, Merck Specialties, Mumbai, India) using the procedure reported earlier [30,[37][38][39][40]. To synthesise MVBS, the three raw materials, viz., boric acid, triethoxy(vinyl)silane and triethoxy(methyl)silane were added in a glass reactor in the mole ratio of 1:0.5:1.5 and stirred for 5 h under reflux in an oil bath maintained at 80-85°C.…”

“…On heat treatment in inert atmospheres, at temperatures between 1200 and 1600°C, MVBS transforms to a SiBOC glassy phase [30,37,38]. Phase stability studies on ceramics derived from siloxanes and borosiloxanes, viz., SiOC and SiBOC, respectively, have revealed that the presence of boron influences the crystallisation [41][42][43].…”

In this study, aluminosilicate fiber-embedded SiBOC matrix composite foams are realised by a simple, cost-effective and easily scalable method. Aluminosilicate wool is transformed into a compressible preform using polyvinyl alcohol as a binder. The preforms are impregnated with methylvinylborosiloxane (MVBS), followed by heat treatment at 1400°C in an inert atmosphere. The composite foam's density, compressive strength and thermal conductivity are modulated in the ranges 0.71-0.46 g/cc, 0.79-0.39 MPa and 0.21-0.13 Wm −1 K −1 , respectively, by varying MVBS concentration from 29 to 54 wt.%. While the incorporation of aluminosilicate fibers was observed to lower the thermal conductivity of the composite foams, it did not contribute to their compressive strength. Exposure of the foams to air at 1300°C for 90 min didn't change their density, while it increased the compressive strength by up to 46% due to improved fiber-matrix adhesion and rounding of cracks.

“…Meanwhile, the amorphous → crystalline transition is usually accompanied by a decomposition reaction, along with the formation of a small amount of gaseous products. In addition, in order to introduce metallic elements into the backbone of the precursor to improve the thermal stability of PDCs, some researchers have also developed inorganic precursors [55]. For example, the most common inorganic precursor is metal chlorides, which are often used to synthesize polymetallosiloxanes with silicic acid and partially hydrolyzed tetraethoxysilanes [56].…”

Ceramics have become indispensable materials for a wide range of industrial applications due to their excellent properties. However, the traditional preparation of ceramic materials is often time-consuming and involves high sintering temperatures. These result in considerable energy consumption and high production costs, which limit the application of these materials in some industries. This paper focuses on the advent of polymer-derived ceramics (PDCs) technology, which enabled the application of ceramics to fibers, composites, coatings, and films, mainly due to the excellent design, process, and low-temperature ceramic properties. We review and evaluate the important research progress made in polymer-derived ceramics technology in recent years and discuss its recent development into high-entropy ceramics. The development of polymer-derived ceramics technology in the field of high-entropy ceramics has broad research prospects, which can greatly improve the understanding and design of high-entropy materials and accelerate their application in the industrial field.
