Abstract
A NO<sub>2</sub> gas sensor integrated with two-dimensional covalent organic nanosheets shows highly sensitive and reliable NO<sub>2</sub> sensing performance even at relatively high humidity levels. The excellent water-repelling ability originates from the superhydrophobic nature of CON surfaces.
