Abstract：
 A method to clad one-dimensional inorganic nanomaterials by living radical polymerization pertains to the technical field of an improved method of one-dimensional inorganic nanomaterials. The invention is characterized in that: gamma-aminopropyl-ethoxysilane or gamma -aminopropyl-trimethoxysilane reacts with hydroxide radical at the surface of the one-dimensional inorganic nanomaterials; brominated propionyl bromide or brominated dibutyryl bromide reacts with modified amidine at the surface of the one-dimensional inorganic nanomaterials, then living radical polymerization is led to realize the polymer cladding of one-dimensional inorganic nanomaterials. The method can be universally suitable for inorganic metal compound nanomaterials, clad one-dimensional inorganic nanomaterials can be comparatively well dispersed in solvents and maintains the basic structure and photoelectric property of one-dimensional inorganic nanomaterials; meanwhile, the invention can comparatively and conveniently control polymer content in materials.
