摘要: 在紫铜表面上制备了聚八氟环丁烷超薄有机聚合物表面,实现了水蒸气的滴状冷凝.对冷凝表面温度进行了实时动态检测,同时测定了表面性能及冷凝传热系数.

Abstract: Dropwise condensation of steam under atmospheric pressure was realized on the polyoctafluorocyclobutane (POFCB) film prepared by plasma polymerization technique. The experimental results were compared with previous studies. The fluctuation of temperature on the condensation surface was measured by a HP 3852A Data Acquisition / Control Unit to confirm the difference of dropwise condensation from filmwise condensation.
