Abstract
Disclosed is a preparation method for crosslinked nanoparticle film. The preparation method comprises: dispersing nanoparticles in a solvent and uniformly mixing same, so as to obtain a nanoparticle solution; and using the nanoparticle solution to prepare a nanoparticle thin film by means of a solution method, and introducing a gas combination to promote a crosslinking reaction, so as to obtain a crosslinked nanoparticle thin film. By introducing a gas combination during film formation of nanoparticles, the present disclosure promotes the crosslinking among particles, and thus increases the electrical coupling among particles, lowers the potential barrier of carrier transmission, and increases the carrier mobility, thereby greatly improving the electrical properties of the thin film.
