Porous superhydrophobic linear low-density polyethylene (LLDPE) surface was prepared by a simple method. Its water contact angle and sliding angle were 153±2° and 10°, respectively. After contamination, 99% of the contaminant particles were removed from the superhydrophobic LLDPE surface using artificial rain. The superhydrophobic LLDPE surface showed high stability in the pH range from 2 to 13. When LLDPE samples were stored in ambient environment for one month, their water contact angle and sliding angle remained constant. Their superhydrophobic property was also maintained after annealing in the temperature range 10-90 °C.
采用一种简单的方法制备了多孔超疏水线性低密度聚乙烯（LLDPE）表面。其水接触角和滑动角分别为153±2°和10°。污染后，使用人工降雨从超疏水LLDPE表面去除了99%的污染物颗粒。超疏水LLDPE表面在pH值为2至13的范围内表现出高稳定性。当LLDPE样品在环境中储存一个月时，其水接触角和滑动角保持不变。在10 - 90°C的温度范围内退火后，它们的超疏水性能也得以保持。
