Easily observed wrinkle
structures comprise various materials.
Because evolutionary wrinkle structures exhibit a broad surface area,
light scattering, and hydrophobicity, the structural advantages of
wrinkles have been exploited in several research fields. Wrinkle structures
have been applied to various materials as well as used in metals,
graphene, and polymers; however, it is extremely difficult to prepare
metal oxide-based wrinkle structures because of the brittle nature
of metal oxide. In this study, a universal method for synthesizing
hierarchical metal oxide wrinkle (hereafter referred to as the H-wrinkle)
structures with precise morphology control was developed. Metal oxide
H-wrinkles were prepared using a polymer sacrificial layer and transferred
for consecutive thermal oxidations on the target substrate. To investigate
the morphological properties of the H-wrinkle, the CuO H-wrinkle was
applied to gas-sensing devices; it showed a sensitivity 6.07 times
greater than that of the pristine CuO film sensors. This significant
improvement corresponding to the unique morphological properties of
H-wrinkles renders considerable adsorption sites and high surface
permeability and subsequently permits the facile penetration of gas
into the sensing layers. In this study, we demonstrated a first example
of the use of the metal oxide wrinkle structure in electronic devices
and thus confirmed its use in various applications.
