Abstract In this study, a high‐entropy perovskite oxide Sr(Zr 0.2 Sn Hf Ti Nb )O 3 (SZSHTN) was first introduced to Na 0.5 Bi TiO (NBT) lead‐free ferroelectric ceramics boost both the high‐temperature dielectric stability and energy storage performance. Excellent comprehensive performance simultaneously obtained in 0.8NBT–0.2SZSHTN ceramic with high ε ′ value (> 2000), wide ′‐temperature stable range (TCC < 5%, 52.4–362°C), low tan δ (<0.01, 90–341°C) ( W rec = 3.52 J/cm , η varies...
Fiber-reinforced hydrogel (FrH) possesses the capability as flexible structural materials. The state-of-the-art FrH left a number of key issues untouched, including interfacial effects and tolerance against salt disturbance. Herein, we report saline-tolerant strong-yet-tough FrH. This is achieved by infiltrating gel-nacre matrix into polyaramid fabric via multiscale reinforcement at interface. incorporation strong yet geometrically compliant skeleton saline-induced shrinking with mechanical...
Severely chronic dermal wounds with irregular rupture shapes or even cavities are calling for injectable and self-biodegradable wound dressings skin lesion complex contours remain a great challenge. Here, we report an injectable, poly(aspartic acid)-l-poly(aspartyl hydrazide) ( PASP-l-PAHy) hydrogel to address these issues. The starting materials were cheap, the new strategy fabrication of acid) based was facile, efficient, mild environmentally friendly, consistent concept green chemistry....
