Abstract

Abstract:

To enhance the liquid transmission capacity of fibrous water evaporator, a trilayer structured polylactic acid/polyethylene glycol@sodium dodecyl sulfate microfiber fabric was designed and prepared using a melt blown-thermal bonding process. The morphology and liquid transmission behavior were assessed through scanning electron microscope, liquid contact angle tester and liquid water management tester. Results indicated that benefiting from the regular distribution of fiber diameter and water wettability in the thickness direction, the prepared samples possessed a large water evaporation rate of 1.27kg/(m²·h) under the solar intensity of 613.52W/m² which resulted from the one-way transport index increased to 533.19% and the liquid absorption rate increased to 2.37mg/s. Besides, the sample exhibited remarkable washability for multiple reuses along with longitudinal and transverse tensile fracture strengths of 67.37N and 35.39N, respectively. This work provided a novel approach to improve the liquid transfer capacity of degradable seawater evaporators.

摘要：

为增强纤维基水蒸发器的液体传输能力，利用熔喷-热熔复合工艺，设计并制备了一种三层复合结构的聚乳酸/聚乙二醇@十二烷基硫酸钠超细纤维材料，通过扫描电子显微镜、液体接触角测量仪和液态水分管理测试仪对其形貌结构和液体传输行为进行表征。结果表明，得益于样品在厚度方向上纤维直径和水润湿能力的规则分布，单向水分传递指数增加到了533.19%、吸液速率增大到了2.37mg/s，从而在613.52W/m²光强下获得了1.27kg/(m²·h)的水蒸发速率。同时，样品表现出优异的可水洗性，利于重复利用，且纵横向拉伸断裂强力分别为67.37N和35.39N，以期为可降解海水蒸发器液体传输能力的提高提供新思路。
