Title:
ORGANIC-INORGANIC HYBRID NANOMATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/048008
Kind Code:
A1
Abstract:
Disclosed is an organic-inorganic hybrid nanomaterial. The organic-inorganic hybrid nanomaterial consists of structural units represented by formula i, formula ii and formula iii. Also disclosed is a preparation method for an organic-inorganic hybrid nanomaterial, comprising: stirring an aqueous solution containing raw materials of a coupled montmorillonite nanomaterial, an organic hydrophobic monomer and an organic hydrophilic monomer, heating same, adding an initiator, and performing a radical polymerization reaction, so as to obtain the organic-inorganic hybrid nanomaterial. The organic hydrophobic monomer is at least one selected from sodium α-alkenyl sulfonate, sodium oleate, potassium oleate and sodium linoleate. The organic hydrophilic monomer is at least one selected from acrylamide and acrylic acid. The preparation method has a simple process and wide sources of raw materials, and is suitable for industrialized production and application promotion. The organic-inorganic hybrid nanomaterial, as a water-soluble nano viscosity reducer, has a significant viscosity reducing effect.
