SCHEDULED MAINTENANCE
Accurate fluorescent polymeric thermometers containing an ionic component
Abstract
Fluorescent polymeric thermometers consisting of only N-alkylacrylamide and fluorescent components show rather low temperature resolution in their functional ranges (ca. 15–50 °C) because of the occurrence of intermolecular aggregation, which causes hysteresis in their fluorescence response to changes in temperature. By adding an ionic component to prevent such intermolecular aggregation, we obtained four fluorescent polymeric thermometers that offer high temperature resolution (<0.2 °C). Each new fluorescent polymeric thermometer covered the temperature range, 9–33 °C, 30–51 °C, 49–66 °C or 4–38 °C.
