Abstract

The invention provides ink and a preparation method thereof and particularly relates to printable ink containing organic-inorganic hybrid perovskite nanocrystals and a preparation method of the ink. The ink is prepared from 0.01wt%-5wt% of the organic-inorganic hybrid perovskite nanocrystals, 70wt%-99wt% of an organic solvent, 1wt%-30wt% of an optical and transparent polymer with a film-forming property and 0.1wt%-10wt% of a stabilizer. The ink has the viscosity ranging from 10 mPaS to 150 mPaS and has the surface tension ranging from 20 mN/m to 70 mN/m.

Description

technical field [0001] The application provides an ink and a preparation method thereof, in particular to a printable ink containing organic-inorganic hybrid perovskite nanocrystals and a preparation method thereof. Background technique [0002] With the rapid development of flexible electronic technology, printed electronic material products on the market are advancing by leaps and bounds. The printed electronic materials that have appeared include organic polymer inks, inorganic nanomaterial inks, and organic polymer inks containing inorganic nanomaterials. Among them, the organic polymer ink containing inorganic nanomaterials has attracted a lot of attention due to its advantages of combining the characteristics of the two materials, and it has great application prospects in the fields of display, energy, environmental protection, transportation, and monitoring. For example, the literature Adv.Mater.2009, 21, 1–5 reported that polyisobutylene is used as the main polymer m...
