Abstract

The invention discloses a preparation method of a kaolin / 1-butyl-3-methyl bromide imidazole intercalated nanocomposite. The method comprises the following steps: firstly, directly intercalating the kaolin by using dimethyl sulfoxide to obtain a kaolin / dimethyl sulfoxide intercalated composite; then intercalating the kaolin intercalated composite by using methyl alcohol to obtain a kaolin / methyl alcohol intercalated composite; and finally, enabling synthesized 1-butyl-3-methyl bromide imidazole and the kaolin / methyl alcohol intercalated composite to carry out intercalating reaction in room-temperature and atmospheric environment so as to obtain a kaolin / 1-butyl-3-methyl bromide imidazole intercalated nanocomposite. Through the preparation method of the kaolin / 1-butyl-3-methyl bromide imidazole intercalated nanocomposite, imidazole ionic liquid carries out intercalating reaction with the kaolin / methyl alcohol intercalated composite under the room-temperature and atmospheric environment for the first time so as to obtain the kaolin / 1-butyl-3-methyl bromide imidazole intercalated nanocomposite; and the kaolin / 1-butyl-3-methyl bromide imidazole intercalated nanocomposite is integral in structure, stable in property, good in heat resistance, fluorescence property and ultraviolet absorbency.

Description

technical field

[0001] The invention relates to a preparation method of a kaolin / 1-butyl-3-methylimidazole bromide intercalation nanocomposite material, belonging to the technical field of organic / inorganic nanocomposite synthesis. Background technique

[0002] Kaolin is a typical layered silicate mineral, and its ideal chemical formula is Al 2 [(OH) 4 / Si 2 o 5 ], is made of [SiO 4 ] tetrahedral hexagonal network layer with [AlO 2 (OH) 4 ] Octahedral layers are formed by a 1:1 combination of layered structures that are periodically repeated in the c-axis direction. In [SiO 4 ] tetrahedron and [AlO 2 (OH) 4 ] In the unit layer composed of octahedra, all the [SiO 4 ] tetrahedral apices are all facing the same direction, pointing to [AlO 2 (OH) 4 ] octahedral, tetrahedral edges are oxygen atoms, and octahedral edges are hydroxyl groups. Due to the interaction of hydrogen bonds and van der Waals forces between crystal layers, overlapping layered stacks are formed, ...
