The present invention makes it possible to: manufacture a CNT-coated substrate, which has a highly dense and uniform CNT film formed thereon and thus exhibits high stability against water or an organic solvent, by using a click reaction; and manufacture a hydrogen gas sensor having excellent reliability and sensitivity by using same. In particular, in contrast to conventional approaches involving spray coating and spin coating of a CNT solution, wherein reproducibility and reliability could not be achieved due to significant differences in physical properties between devices, the present invention makes it possible to manufacture a hydrogen gas sensor having excellent selectivity and sensitivity to hydrogen gas, while also having high reproducibility and reliability, using a relatively simple method. La présente invention permet : de fabriquer un substrat revêtu de CNT, qui comporte un film de CNT hautement dense et uniforme formé sur ce dernier et présente ainsi une stabilité élevée contre l'eau ou un solvant organique, à l'aide d'une réaction click ; et de fabriquer un capteur de gaz hydrogène présentant une excellente fiabilité et une excellente sensibilité à l'aide de ce dernier. En particulier, contrairement aux approches classiques impliquant un revêtement par pulvérisation et un revêtement par centrifugation d'une solution de CNT dans lesquelles la reproductibilité et la fiabilité ne pouvaient pas être obtenues en raison de différences significatives de propriétés physiques entre les dispositifs, la présente invention permet de fabriquer un capteur de gaz hydrogène présentant une excellente sélectivité et une excellente sensibilité gaz hydrogène, tout en présentant également une reproductibilité et une fiabilité élevées, à l'aide d'un procédé relativement simple. 본 발명은 클릭반응을 이용하여 CNT 필름이 고밀도로 균일하게 형성되어 물이나 유기 용매에 대한 높은 안정성을 나타내는 CNT 코팅 기판을 제조할 수 있고, 이를 이용하여 신뢰성 및 민감도가 탁월한 수소 가스 센서를 제조할 수 있다. 특히, 종래에 CNT 용액을 스프레이 코팅 및 스핀 코팅할 경우 소자간 물성차이가 커 재현성 및 신뢰성을 확보할 수 없었던 반면, 본 발명에서는 비교적 간단한 방법으로 높은 재현성 및 신뢰성을 가지면서도 수소 가스에 대한 선택도 및 민감도가 탁월한 수소 가스 센서를 제조할 수 있다.
