The invention discloses a temperature and
humidity dual-
response type liquid crystal screen display packaging material and a preparation method thereof, and application of the temperature and
humidity dual-
response type liquid crystal screen display packaging material in
liquid crystal screen display packaging. According to the preparation method, organic
silicon resin, a
silane coupling agent modified nano SiO2 / Al2O3
composite material, an intelligent response additive PNIPAM / PEG, an
ultraviolet light absorber, a
silane coupling agent and auxiliaries are used as raw materials, and the packaging material is obtained through the processes of premixing, vacuum defoaming, low-
humidity vacuum curing and the like. By introducing an intelligent response additive
system containing a temperature-sensitive
polymer and a humidity-sensitive
polymer, the packaging material is endowed with the capability of actively sensing and responding to the change of ambient temperature and humidity, so that the real-time and reversible regulation and control of key properties such as modulus,
hardness, barrier property and the like are realized. The packaging material can more effectively protect a liquid
crystal layer in a complex and changeable environment, the display stability and reliability of a liquid
crystal screen are remarkably improved, and the service life of the liquid
crystal screen is remarkably prolonged.
