Abstract

The present disclosure relates to the technical field of functional liquid crystal materials, and discloses a liquid crystal film with an intelligent information encryption function and a preparation method and use thereof. The liquid crystal film includes two layers of parallel transparent substrates and a composite functional layer between the transparent substrates; and the composite functional layer includes a honeycomb-shaped polymer matrix and liquid crystals filled in pores of the polymer matrix, where the liquid crystals comprise a polymer network; and the distribution density of the polymer network varies in different regions of the liquid crystal film, thereby allowing the liquid crystal film to exhibit a reversible changing information pattern that disappears (or appears) upon application of an electric field and appears (or disappears) after removal of the electric field, or a reversible changing information pattern that disappears (or appears) at low temperatures and appears (or disappears) at high temperatures.
