Abstract

The invention discloses a manufacturing method of an infrared reflecting device. The manufacturing method of the infrared reflecting device comprises the following steps: making a first conductive light transmitting substrate and a second conductive light transmitting substrate at first, and enabling the two conductive light transmitting substrate to opposite to each other; manufacturing parallel orientation layers on the opposite surfaces of the two conductive light transmitting substrates; manufacturing a liquid crystal box by using the two conductive light transmitting substrates; mixing negative liquid crystal, a chiral dopant, liquid crystal monomers and a photoinitiator to obtain a liquid crystal mixture; injecting the liquid crystal mixture in the liquid crystal box; connecting the first conductive light transmitting substrate with a negative pole of a power supply assembly, connecting the second conductive light transmitting substrate with a positive pole of the power supply assembly, capturing impurity positive ions by using the liquid crystal monomers and / or the chiral dopant so that the liquid crystal monomers and / or the chiral dopant have positive charge, and enabling the liquid crystal monomers and / or the chiral dopant to continue moving towards the negative pole direction; and carrying out ultraviolet irradiation to polymerize the liquid crystal monomers so as to form a polymer network, and enabling the densities of the polymer network to be distributed in a gradient manner in the direction perpendicular to the conductive light transmitting substrate to obtain the infrared reflecting device with wide reflection bandwidth. By change of the direction of an electric field, infrared reflection waveband can be adjusted.

Description

technical field [0001] The invention relates to the technical fields of optics and liquid crystal devices, in particular to a preparation method of an infrared reflective device. Background technique [0002] People generally work indoors, so the comfort of the indoor environment has a great impact on people's enthusiasm for work. Indoor and other environments generally use cooling or heating devices to adjust the temperature to achieve comfort. [0003] In order to achieve the purpose of sunlight transmission and reflection, the glass is generally coated so that light of a certain wavelength in the light can be reflected or transmitted by the glass window. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass and achieve the purpose of reflecting or transmitting light of a certain wavelength. [0004] However, after the coated glass is formed, its optical properties ...
