Description

technical field [0001] The invention belongs to the technical field of semiconductor coatings, in particular to a carbon nanotube coating on the electrode surface of metal and carbon-based materials and a preparation method thereof. Background technique [0002] In the field of coatings, high-quality coatings can play a powerful interface role. Especially in the application of the electrode surface, the performance of the coating quality directly affects the catalytic and conductive properties of the electrode. The existing conductive coatings have many shortcomings. On the one hand, the poor toughness of these materials makes it difficult to apply in flexible on the substrate. On the other hand, due to their poor environmental pH resistance and aging resistance, complex preparation process, and high cost of raw materials, their prices are relatively high. [0003] Carbon nanotubes play a pivotal role in the field of electronic devices due to their excellent electrical, me...
