Abstract

The invention discloses a luminous functional composite material, which is a composite material of polystyrene and inorganic nano-oxides, characterized in that: the polystyrene is polystyrene with carboxylic acid functional groups at both ends, The material is selected from nanometer titanium dioxide, composite oxide of nanometer titanium dioxide, copper and chromium, nanometer zinc oxide or nanometer zinc-aluminum composite oxide. The preparation method is to synthesize polystyrene with benzoic acid unit at one end and chlorine atom at the other end by atom transfer radical polymerization; Polystyrene; final modification with inorganic nano-oxides. The polymer / nanoparticle composite material obtained by the present invention has red shift or blue shift relative to the fluorescence emission spectrum of the polymer, and becomes a new way to adjust the emission spectrum; at the same time, the composite material has good solubility and film-forming properties , has potential application value in light-emitting devices.

Description

technical field

[0001] The invention relates to a luminescent functional composite material composed of a polymer and an inorganic nanometer oxide and a preparation method thereof, in particular to a composite material composed of polystyrene containing a specific end group and an inorganic nanometer oxide. Background technique

[0002] Since the advent of nanomaterials in the 20th century, people have done a lot of research in this field and achieved many results. In particular, inorganic nano-oxides have many special properties. For example, nano-TiO 2 It is a stable non-toxic ultraviolet light absorber, which can be combined with polymers to improve the aging resistance of polymers; nano-TiO 2 It also has photocatalytic activity, can degrade organic pollutants under light conditions, kill bacteria, and can make functional coatings; TiO 2 Nanoparticle thin films have broad application prospects in solar cells, antireflection coatings, insulating layers, photoelectrodes,...
