Abstract(#br)Conductive nanofiber composites (CNCs) are promising as wearable strain sensors (WSSs) due to their unique porous structure and thus good breathability, flexibility, skin affinity, and so forth. It still remains a great challenge to develop flexible and stretchable CNCs for high performance WSSs that possess a high sensitivity, large working strain and can also be applied in various harsh conditions such as extremely cold and corrosive environment.

利用焦耳热效应和光热效应,从木质化木材中制备可压缩碳海绵,用于快速清理和提高原油溢油回收率

快速、高效地清理原油泄漏仍然是全球性的挑战,因为大部分原油是高粘度、低流动性的。本文报道了一种具有良好压缩性和疏水性的聚二甲基硅氧烷修饰的木质碳海绵( PDMS @ WCS ),通过促进焦耳加热和光热效应,快速吸附和提高原油采收率。此外,PDMS @ WCS可以在50 %的恒定应变下进行多次压缩和释放,不会因PDMS涂层的保护而造成结构损伤。因此,在外压作用下,吸附的原油可以很容易地被排除在PDMS @ WCS之外,提高采收率。
