“…If they were mainly derived from H 2 O radiolysis, valance reduction can be feasible. This situation is feasible as H 2 O radiolysis cannot be avoided under EB irradiation 42,44,51,52 . Considering these aspects comprehensively, it concludes to 1000 kGy‐irradiated species dehydroxylation is extensive accompanied with H 2 O radiolysis.…”

Electronic components made by inorganics (e.g., mica) play key roles in function exertion of instruments working in outer‐layer space, enduring long‐term β ray irradiation. Its damage is vital while explored rarely. Herein, pure muscovite crystals were chosen and irradiated by an electron beam (EB) in air with dose up to 1000 kGy. Then, micro‐geometry morphology variation in Z‐axis and microstructural transformation mechanism were explored by XRD, FT‐ATR IR, TGA, XPS and CA analysis. Main results reveal that muscovite lattice is unstable to EB irradiation. With dose increases to 1000 kGy interlayer space d of (002) lattice varied 2% near 0.2 Å. At low dose irradiation lattice expansion is readily to occur while at higher dose it is lattice shrinkage, showing a transformation from expansion to shrinkage. Concurrently, chemical structure varied, H2O amount increased, metal element valance and surface wettability were reduced. Where, dehydroxylation occurred exceeding H2O radiaolysis and evaporation, and framework cleavage be severe. Binding energies of metals of 1000 kGy‐irradiated species decreased by 0.2 eV, CA of 100 kGy‐irradiated species increased by 10°. Intrinsic mechanisms involve framework destruction, H‐atom migration, hydrogen bond formation/destruction and H2O radiolysis. At low dose irradiation, H‐atom migration and hydrogen bond formation/destruction are predominant, inducing lattice expansion; at higher dose, framework cleavage is intensive and crucial, inducing shrinkage. During which, partial H2O occurred radiolysis, reducing valence. Generally, H‐atom migration and interface cleavage played key roles in microgeometry morphology variation of muscovite crystal under EB irradiation at 0–1000 kGy. To enhance muscovite geometry morphology‐stability under a long‐term β‐ray irradiation condition OH and hydrogen bond contents should be reduced and interface region should be strengthened (e.g., lessening vacancies or compacting stacking). This conclusion promotes design of radiation‐resistant silicate material, guiding manufacture of electronic component used in aerospace industry, significant.This article is protected by copyright.

“…The subtracted graphs are also presented in Figure 2a. The diffraction peaks of talc at 9.47 • , 18.95 • , and 28.64 • are related to the interlayer space of talc corresponding, respectively, to the (002), (004), and (006) planes [32,33]. As can be seen in Figure 2a, the subtracted graph referring to the talc modified at 12 • C exhibits clear negative peaks at the abovementioned angles, indicating that the intensity of these peaks is reduced in the modified sample.…”

A large amount of the polypropylene (PP) produced worldwide is used in the form of fibers. In this work, a new modification route for talc and PP is investigated, which is based on the in situ polymerization of a silane–siloxane monomer mixture on the surface of talc particles or PP pellets, respectively. The obtained modified talc and PP samples were used for the development of PP-talc composite drawn fibers. Tensile tests, thermogravimetry (TGA), and X-ray diffraction (XRD) were used for the characterization of the materials. It was observed that such a modification procedure resulted in the exfoliation of some talc particles. Enhanced tensile strength was observed for composite drawn fibers of a low talc content (1% with respect to PP) and a low modifier content (2% with respect to talc), while co-aggregation of talc and silicone may occur at high silicone and talc contents, resulting in the inferior mechanical performance of the corresponding composites. It was concluded that the produced silicone polymer simultaneously acts as a modifier, antioxidant, and compatibilizer. The proposed modification route is promising and should be further optimized.

Energy storage capacitors occupy a large proportion in the pulse power equipment, and they play an important role nowadays. In recent years, anti‐ferroelectric materials have attracted increasing attention of researchers due to their high energy storage density. Compared with the lead‐free anti‐ferroelectric materials, PbZrO3 (PZ)‐based anti‐ferroelectric films are defined as promising electrical energy storage devices for pulsed power systems due to their ultrahigh energy storage density. During the past decade, numerous studies have been reported to develop high‐performance PZ‐based anti‐ferroelectric thin films for electrical energy storage applications. This review focuses on the recent progress of PZ‐based anti‐ferroelectric films for energy storage, and provides various ways, such as element modification (replacing of one element in the ABO3 structure by another element), composite materials (adding secondary phase into PZ films to form composite films), and process improvement (such as the tuning of different bottom electrodes), to improve their energy storage density. Finally, the problems and future development directions of the PZ‐based films are raised.
