CNT FILM COATED SUBSTRATE USING CLICK REACTION AND MANUFACTURING METHOD THEREOF

Nº publicación: JP2022165397A 31/10/2022

Solicitante:

コリアリサーチインスティテュートオブケミカルテクノロジー

KR_20220144255_PA

Resumen de: US2022340761A1

Provided is a CNT film coated substrate in which CNT is fixed to a substrate using a click reaction, so that a CNT film is uniformly formed with a high density and adhesive strength between the CNT film and the substrate is excellent to have high stability to water or an organic solvent. In the case of the conventional CNT film which was manufactured by spin coating, most of CNT was peeled off in a washing process, but in the case of the CNT film coated substrate according to the present invention, a high-density uniform CNT film coated substrate may be manufactured even after washing, and reproducibility between substrates may be secured.
