(9) Referring to FIG. 1, step S100 is performed to mix at least two types of precursors selected from a transition metal precursor and a metalloid precursor and a cation precursor in a solvent.

(10) The transition metal precursor is, for instance, transition metal alkoxide, and the metalloid precursor is, for instance, metalloid alkoxide, but the invention is not limited thereto. The alkoxide can have one or more alkoxy groups. For instance, the alkoxide can be methoxide, ethoxide, propoxide, butoxide, isopropoxide, isobutoxide, 2-ethylhexyloxide, oxytrimethoxide, oxytriethoxide, oxytripropoxide, oxytriisopropoxide, or a combination thereof.

(14) Step S102 is performed to react the at least two types of precursors of the transition metal precursor and the metalloid precursor and the cation precursor to obtain a metal bronze compound represented by formula (1). Formula (1) is described in detail above and is therefore not repeated herein.

(15) The reaction can be performed at room temperature, and at this point, the reaction and aging occur at the same time. Room temperature can generally be defined as 4° C. to 40° C. Specifically, a self-generated irreversible chemical reaction occurs to the precursors after mixing at room temperature to produce a metal bronze compound. Moreover, during the reaction process, additional heating, acid, or base is not needed, and a violent exothermic reaction does not occur, and therefore an ice bath is not needed as the reaction can end on its own.

(16) When the reaction is performed at room temperature, the reaction time is, for instance, 6 hours to 28 days. For instance, the reaction time can be 24 hours, 48 hours, 72 hours, or 92 hours, but the invention is not limited thereto. Those having ordinary skill in the art can adjust the reaction time according to process requirements.

(17) Moreover, if a faster reaction is desired, then the reaction can also be performed at low temperature. That is, the mixed solution can be heated to a low temperature range to perform the reaction. The low temperature can generally be defined as greater than 40° C. and 200° C. or less, such as greater than 40° C. and 180° C. or less. When the reaction is performed at low temperature, the reaction time is, for instance, 5 minutes to 96 hours, but the invention is not limited thereto. Those having ordinary skill in the art can adjust the reaction time according to process requirements.

(18) Moreover, after the reaction is performed at low temperature, the mixed solution can be cooled to room temperature for aging. The aging time is, for instance, 0 minutes to 14 days. For instance, the aging time can be 24 hours, 48 hours, 72 hours, or 92 hours, but the invention is not limited thereto. Those having ordinary skill in the art can adjust the aging time according to process requirements.

(19) After the reaction is performed, the mixed solution having a metal bronze compound can be used as ink. In other embodiments, the mixed solution having a metal bronze compound can also be used as ink after other solvents and/or additives are optionally added in the mixed solution having the metal bronze compound to further adjust the viscosity, tension, volatility, post-film-forming porosity, and film uniformity and adhesion of the ink. Therefore, the ink of the present embodiment includes a metal bronze compound, and can further include a solvent. Moreover, the ink can further optionally include other solvents and/or additives to adjust the properties of the ink.

(20) Moreover, the ink of the present embodiment can be used to form various functional films such as a protective film, sensing film (such as an organic volatile gas sensing film), or a photocatalytic film. Since the ink of the present embodiment has the metal bronze compound, the ink can achieve better physical properties and is suitable for various wet processes without producing additional manufacturing costs and manufacture difficulty. The forming method of the film includes, for instance, performing deposition on the ink. The method of ink deposition includes, for instance, printing, spin coating, spray coating, dip coating, or roll-to-roll. The printing includes, for instance, 3D printing, inkjet printing, gravure printing, screen printing, elastic printing, or lithography.

(21) Moreover, since the film thickness of the wet film having the metal bronze compound formed by the ink is changed during the forming of a dry film, if other deposition materials are first formed on the substrate, then changes to the film thickness results in denser and flatter deposited materials due to the capillary phenomenon. Moreover, if the original deposition materials are less stable, then the forming of a metal bronze compound film on the surface of the deposited materials can provide a protection effect.

(22) Although the invention has been described with reference to the above embodiments, it will be apparent to one of ordinary skill in the art that modifications to the described embodiments may be made without departing from the spirit of the invention. Accordingly, the scope of the invention is defined by the attached claims not by the above detailed descriptions.
