Disclosed is a thermoresponsive polymer gel for which the mass decreases from the maximum water-containing state to 20% or less of said maximum water-containing state within 300 seconds due to heat stimulation, or for which the difference in the surface water droplet contact angle before and after heat stimulation is 20° or higher; further disclosed is a thermoresponsive polymer gel film obtained by forming said thermoresponsive polymer gel in the shape of a film. With this thermoresponsive polymer gel film, due to heat stimulation the degree of swelling changes rapidly or the water droplet contact angle of the gel surface changes greatly. |
