Abstract

The invention discloses a zinc oxide nanoparticle stable solution, and a zinc oxide-polymer nano composite material stable solution, a preparation method and applications thereof, wherein the zinc oxide nanoparticle stable solution contains zinc oxide nanoparticles and a stabilizer, and the stabilizer is low-boiling-point amine. According to the invention, the low-boiling-point amine is added intothe solution as a stabilizer, so that the zinc oxide nano particles with good dispersion property and the nano composite material can be effectively kept in the solution for several days under environmental conditions, wherein the low-boiling-point amines such as propylamine, butylamine, isobutylamine and the like can be self-dissociated into small organic compounds at room temperature, and the organic compounds are easy to evaporate in air at room temperature; and when the nano composite material is deposited on a base material, the low-boiling-point amine can be self-dissociated to be completely removed, so that the stable nano composite material film with good performance is obtained.

Description

technical field [0001] The invention belongs to the field of material chemistry. More specifically, it relates to a stable solution of zinc oxide nanoparticles, a stable solution of zinc oxide-polymer nanocomposite material and their preparation and application. Background technique [0002] Metal oxide-polymer composites have received extensive attention in the optoelectronics industry. A good example is the zinc oxide-P3HT composite. P3HT is an expensive semiconducting polymer that is well studied in electronics, while metal oxides are less expensive to obtain but have fewer unique properties. Therefore, metal oxide-polymer composites may provide a cost-effective solution for fabricating inexpensive, well-performing devices with unique functions and aspects. [0003] US Patent US20070004840 discloses a nano-zinc oxide-polymer nanocomposite and a preparation method thereof, in which the zinc oxide nanoparticle-polymer composite is synthesized in a solution. The obtained...
