Summary: | The invention discloses a visual polymer thermometer with a temperature memory function and a preparation method thereof, and belongs to the field of polymer temperature sensors. The method comprises the following steps: (1) polymerizing a hydrophilic monomer, a hydrophobic monomer, an LCST type temperature-sensitive monomer or an LCST type temperature-sensitive polymer chain and a derivative of a triple or multiple hydrogen bond unit in the presence of an initiator to prepare an LCST type temperature-sensitive polymer material containing the triple or multiple hydrogen bond unit; and (2) the hydrogel prepared by aqueous solution/dispersion or further crosslinking of the materials can be used for a polymer thermometer with programmable memory temperature and adjustable memory time. The low critical solution temperature, namely the measurement temperature, of the high polymer material is adjusted by adjusting the proportion of the hydrophilic monomer and the hydrophobic monomer, the temperature response and me |
