用于表征聚合物溶液的温控浊度测量装置已经安装完毕。主要特点是通过珀耳帖元件实现温度-透光率耦合测量和精确的温度控制。该装置允许通过采用不同的冷却方案来测量浊点温度：低速率用于准平衡测量，高速率用于检测动力学效应。采用三元聚合物溶液作为案例研究系统，表明冷却速率会影响测量的浊点温度。
A temperature-controlled turbidity measurement apparatus for the characterization of polymer solutions has been instrumented and set up. The main features are the coupled temperature-light transmittance measurement and the accurate temperature control, achieved by means of peltier cells. The apparatus allows to measure cloud point temperatures by adopting different cooling protocols: low rate for quasi-equilibrium measurements and high rate for detect kinetic effects. A ternary polymeric solution was adopted as case study system showing that cooling rate affects the measured cloud point temperature.
