Temperature-responsive polymers or thermoresponsive polymers are polymers that exhibit a drastic and discontinuous change of their physical properties with temperature. The term is commonly used when the property concerned is solubility in a given solvent, but it may also be used when other properties are affected. Thermoresponsive polymers belong to the class of stimuli-responsive materials, in contrast to temperature-sensitive (for short, thermosensitive) materials, which change their properties continuously with environmental conditions. In a stricter sense, thermoresponsive polymers display a miscibility gap in their temperature-composition diagram. Depending on whether the miscibility gap is found at high or low temperatures, an upper or lower critical solution temperature exists, respectively (abbreviated UCST or LCST).
Temperature-responsive polymer and smart window comprising the same
The application provides a temperature-responsive polymer, which comprises a repeating unit shown in the following formula I; the formula I is a polymerization product of two monomers of 2-(2-methoxyethoxy)methyl acrylate (MEO2MA) and 2-(2-hydroxyethoxy)ethyl methacrylate (HEO2MA); in the formula I, x is 1-100; y is 20-500. The smart window prepared from the temperature-responsive polymer has the characteristics of wide temperature response range, high light transmittance, excellent heat insulation performance and long-term stability, and can be widely applied to light-collecting and temperature-controlling parts in various scenes such as residential buildings, commercial buildings and public facilities, and has significant energy-saving value and market prospect.

Control methods for the ionic conductivity of temperature-responsive polymers
This invention provides a novel method for controlling ionic conductivity using a polymer solution that dissolves in an organic solvent at low temperatures to form a transparent solution and undergoes phase separation upon heating; specifically, a temperature-responsive polymer that induces lower critical solution temperature (LCST) type phase separation. The method allows the ionic conductivity of a temperature-responsive ionic solution containing a temperature-responsive polymer, a salt, and an organic solvent, wherein the salt dissociates into ionic components, to change with temperature. Preferably, the temperature-responsive polymer is one that exhibits LCST type phase separation.

Disclosed herein is a light control glass that can be produced through a simple process and can offer stable performance. The light control glass includes transparent substrates facing each other and a light control material disposed between the transparent substrates, the light control material being a mixture of a temperature-responsive polymer (PNIPAM) having a lower critical solution temperature and a material (thermoreversible gelation polymer: TGP) that turns into a gel at a temperature equal to or lower than the lower critical solution temperature. In addition, FTO or ITO may be disposed on the surfaces of the transparent substrates being in contact with TGP.
