Abstract

AbstractWafer‐scale vertically aligned carbon nanotube/poly(vinyl alcohol) (VACNT/PVA) hydrogels are fabricated by infiltration of PVA among VACNTs and subsequent in situ hydrogelation. Owing to the homogeneous PVA infiltration, uniform distribution and orientation of the carbon nanotubes (CNTs) are well retained, which in turn provide large CNT‐PVA interfaces throughout the resulting hydrogels. Compared to bare PVA hydrogels, such composite hydrogels perform significantly enhanced longitudinal compressive responses upon both static and dynamic loadings, achieving improvements of up to 25.2‐ and 9.0‐fold in strength and loss modulus, respectively. The novel scalable fabrication of VACNT/PVA hydrogels and their attractive performances hold great potential for a wide range of applications.
