Title:
COMPOUND DISPERSANT AND PREPARATION METHOD, AND MIXED ELECTROPLATING SOLUTION AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/206927
Kind Code:
A1
Abstract:
The present invention relates to the technical field of materials, and in particular, to a compound dispersant, which is composed of distilled water, a nonionic surfactant, and a wetting agent; the nonionic surfactant is a Tween compound, and the wetting agent comprises a hydrocarbyl sulfate compound and a hydrocarbyl sulfonate compound. The compound dispersant can effectively block or slow down the agglomeration of graphene in a dispersion. The present invention also relates to a preparation method for a compound dispersant. The preparation method is simple to operate, and the prepared compound dispersant can effectively block or slow down the agglomeration of graphene in a dispersion. The present invention also relates to a mixed electroplating solution comprising the compound dispersant. The graphene in the mixed electroplating solution is dispersed evenly and stably. The present invention also relates to a preparation method for a mixed electroplating solution. The preparation method is simple to operate, and the graphene in the prepared mixed electroplating solution is dispersed evenly and stably.
