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.

The invention relates to the technical field of traditional Chinese medicine external preparations, and discloses a traditional Chinese medicine cataplasm matrix formula for promoting blood circulation to remove blood stasis and preventing DVT. 8-15 parts of radix salviae miltiorrhizae; 5-10 parts of ligusticum wallichii; 5-10 parts of safflower; 3-8 parts of earthworm; 3-7 parts of poria cocos; 0.5 to 2 parts of borneol; 10 to 20 parts of a temperature responsive polymer; 5-15 parts of a pressure responsive polymer; 15 to 25 parts of a biodegradable high polymer material; and 1-5 parts of a biocompatibility auxiliary agent. Through the combination of the temperature-responsive polymer and the pressure-responsive polymer, the temperature-responsive polymer ensures the sufficient release of the medicine and prevents the formation of thrombus when the patient lies still in the early stage after the operation; and during later-stage activity, the drug release amount can be automatically reduced, so that skin irritation caused by excessive drugs is avoided, the anti-thrombus effect is ensured, drug residues are reduced, and the comfort and safety of treatment are improved.

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.

A tri-block copolymer includes a first end block consisting of a hydrophobic, nano-fiber forming polymer, wherein the first end block is present in the tri-block copolymer at a weight percentage ranging from about 10% to about 89%; a middle block attached to the first end block, the middle block consisting of a hydrophilic polymer, wherein the middle block is present in the tri-block copolymer at a weight percentage ranging from about 1% to about 89%; and a second end block attached to the middle block, the second end block consisting of a temperature-responsive polymer, wherein the second end block is present in the tri-block copolymer at a weight percentage ranging from about 1% to about 89%.

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.
