Description

technical field

[0001] The reactive functional polymer / Al involved in the present invention 2 o 3 The invention relates to a method for preparing nanocomposite particles, which belongs to the technical field of polymer materials. Background technique

[0002] In recent years, more and more nanocomposite technologies have been introduced in the field of polymer materials, and researchers often use various inorganic powders including SiO 2 、Al 2 o 3 , ZnO, TiO 2 Wait to carry out filling modification on the polymer material matrix. However, since the powder itself is an inorganic substance and the filled material is an organic polymer, the compatibility between the two is poor, which leads to poor dispersion of inorganic powder particles in the matrix and weak interfacial interaction. , so the filling effect is also very limited. The preparation technology of polymer / inorganic powder nanocomposites can make the product have the characteristics of both inorganic nanopart...
