Abstract: A liquid crystal/polymer composite electrically controlled dimming film is provided, including a liquid crystal material, a polymer matrix, and two layers of conductive substrates. The polymer matrix is sandwiched between the two layers of conductive substrates, and the polymer matrix has a porous microstructure. The liquid crystal material is dispersed in the polymer matrix to form liquid crystal microdroplets, and the liquid crystal microdroplets have vertically oriented polymer networks. The liquid crystal/polymer composite electrically controlled dimming film has a unique composite microstructure. In this composite microstructure, the polymer matrix of the porous microstructure gives the film with good mechanical processing performance.

Abstract: The present invention relates to a temperature-controlled dimming film with a function of shielding near-infrared light, which comprises a polymer network skeleton and liquid crystal molecules, wherein the polymer network skeleton consists of a polymer-dispersed liquid crystal network structure and a polymer-stabilized liquid crystal network structure and comprises a polymer matrix with pores inside which polymer networks are vertically aligned; and the liquid crystal molecules are dispersed in the polymer network skeleton and have smectic (SmA)-cholesteric (N*) phase transition. Between the skeleton and the liquid crystal molecules, nanoparticles, having absorption at 800-3000 nm, are dispersed. In the invention, a stepwise polymerization method is utilized to construct a PD&SLC network structure between two substrates, which greatly improve the bonding strength between the two substrates and the heat insulation performance of the temperature-controlled liquid crystal dimming film.
