“…They are prone to degradation of their strength and embrittlement when subjected to high-thermal loads, which is normally associated with the degradation of the fibers [10][11][12]. Early studies by Wilson [13] showed that the aforementioned fibers present strength loss when tested at temperatures above 1000°C.…”

“…They are supplied by 3M Corporation (Nextel fibers), Sumitomo Corporation (Altex fibers) or Mitsui Mining (Almax fibers) and their cost is relatively low. 14) They are in general used for heat-insulating covers and furnaces. However this type of fibers suffers from grain growth and creep at high temperatures which are limiting factors for long periods of usage.…”

High-temperature ceramic materials gain a continuous growing interest due to the various properties they can offer. Among all their specific features, their outstanding thermal and mechanical stability attract much attention to save energy. In the category of ceramics, silicon-based non-oxide compositions display a great potential for many applications involving high temperatures, high stresses or harsh environments. Since the major binary silicon carbide and silicon nitride, which are currently used as highperformance ceramics, were discovered, the role of chemistry in the design of materials has become major. Its potential lies in the exploitation of new chemical systems and the development of new preparative routes. As a consequence, new ceramic properties can be envisioned. The polymer derived ceramic (PDC) route is a "ceramic through chemistry" concept which allows synthesizing new materials in terms of compositions and shapes difficult to tailor using more conventional approaches. This review highlights the works made in the last decades concerning the preparation of PDC fibers with a particular focus on amorphous SiCN and SiBCN networks using melt-spinning and electrospinning processes of preceramic polymers. One main emphasis of this review is set on addressing the intimate relationship between molecular structure/architecture of preceramic polymers, their spinning/ curing/pyrolysis behavior and the properties of the final fibers.

“…There, the inorganic block segmentalso referred to as preceramic block segmentis directly converted into the ceramic material after thermal treatment maintaining the block copolymer-templated nanostructure. [48][49][50] More basic requirements for well-defined microphase separation of block copoly-mers are e.g., precise control over blocking efficiency and narrowly distributed polymer masses. [23][24][25][26][27][28][29] All these above mentioned powerful applications based on block copolymers necessitates the precise synthesis of the underlying block copolymer architectures comprising adjustable block length and exact (block) polymer constitution.…”

A novel and feasible strategy for the preparation of functional polyhydrocarbosilane-based homo and block copolymers is described via a combination of anionic ring-opening polymerization of methylsilacyclobutane (MSB) and styrene followed by postmodification applying hydrosilylation protocols. Sterically demanding and functional vinyl compounds such as N-vinylcarbazole (NVC), vinylferrocene (VFc), and 9,10-di(1-naphthalenyl)-2-vinylanthracene (VADN) are block-selectively incorporated into the PMSB backbone with adjustable functional group contents between 26 mol% to 43 mol% with respect to the Si-H functionalities for the PMSB homopolymers and contents ranging from 28 mol% to 63 mol% for the corresponding diblock copolymers as evidenced by 1 H NMR spectroscopy. The novel functional diblock copolymers are capable of undergoing microphase separation as shown via TEM. † Electronic supplementary information (ESI) available: Additional data on PMSB homopolymers, 1 H NMR spectra, SEC, and DSC of all functional hydrosilylated PMSB homo-and block copolymers, 1 H NMR spectrum of NVC@PS-b-PMSB1 precipitated in methanol, cyclic voltammogram of VFc@PMSB1, TGA of VFc@PMSB1, and XRD pattern of ceramized VFc@PMSB.
