Abstract

Wrinkles formed during the drying of polymer films by hot-air flow but not when drying by infrared irradiation, even though drying rates were comparable. The top surface was hotter than the bottom during hot-air drying. Conversely, the temperatures of the top and bottom surfaces were very similar when drying by infrared irradiation. We also examined uniform heating with faster and slower drying rates using drying with combined infrared irradiation and air flow (hot or room temperature). Wrinkles formed in both cases. This demonstrated the negative effect of air flow. Features and mechanism of each drying method are discussed.

干燥方法如何影响薄膜的质量？在热空气流或红外线加热下以相当的蒸发速率干燥聚合物溶液

摘要

在通过热气流干燥聚合物薄膜的过程中形成皱纹，但在通过红外线照射干燥时不会形成皱纹，即使干燥速率相当。在热空气干燥期间，顶部表面比底部更热。相反，当通过红外线照射干燥时，顶面和底面的温度非常相似。我们还使用结合红外辐射和气流（热或室温）的干燥来检查均匀加热和更快和更慢的干燥速率。在这两种情况下都形成了皱纹。这证明了气流的负面影响。讨论了每种干燥方法的特点和机理。
