Method for preparing humidity-sensitive film of quasi-three-dimensional structure
The invention relates to the technical field of humidity-sensitive films, in particular to a method for preparing a humidity-sensitive film of a quasithree-dimensional structure. The method for preparing the humidity-sensitive film comprises the following steps that 1, a solvent is prepared; 2, Mn-Co-Ni-O ternary transition metal oxide precursor liquid is prepared; 3, Mn-Co-Ni-O ternary transition metal oxide film sol is prepared; 4, ageing is carried out; 5, a film is thrown; 6, heat treatment is carried out. According to the method for preparing the humidity-sensitive film of the quasi-three-dimensional structure, the prepared humidity-sensitive film is of the quasi-three-dimensional structure, and is in a sheet-shaped three-dimensional net shape, therefore, the humidity-sensitive film of the quasi-three-dimensional structure is high in sensitivity and response and restoration speed, and the high response and restoration speed means that response and restoration time is short. In addition, compared with humidity-sensitive films of a nanowire array structure, a nanosheet array structure and other three-dimensional structures, the prepared humidity-sensitive film of the quasi-three-dimensional structure has high mechanical properties such as dropping resistance and crushing resistance, and is high in mechanical stability.
