This study describes the development of a fog collector material for fog harvesting. Polypropylene (PP) doped with fumed silica (0–2%) was punctured at equal intervals and exposed to fog produced by a humidifier. The amount of water harvested by each sample was measured using an ultrasonic fogger. Polypropylene doped with 1% fumed silica was most effective at harvesting water, and collected almost 19–20 times more water than pure polypropylene. This improvement is due to the surface tension, which decreased from 16.754 mN/m (pure PP) to 13.512 and 9.992 mN/m (0.5% and 1% fumed silica, respectively). On the other hand, when fumed silica doping exceeded 1%, this increased the polymer’s surface tension, measured as 20.6 and 38.1 mN/m for 1.5 and 2% fumed silica doping. We therefore propose fog harvesting using 1% fumed silica-doped polypropylene as a low-cost method for collecting clean water in arid regions.

这项研究描述了用于雾气收集的雾气收集器材料的开发。将掺杂有气相二氧化硅（0–2％）的聚丙烯（PP）以相等的间隔刺穿，并暴露于加湿器产生的雾气中。使用超声雾化器测量每个样品收集的水量。掺有1％气相法二氧化硅的聚丙烯在收获水方面最有效，并且收集到的水几乎是纯聚丙烯的19-20倍。这种改善是由于表面张力从16.754 mN / m（纯PP）降至13.512和9.992 mN / m（分别为0.5％和1％气相二氧化硅）。另一方面，当气相二氧化硅的掺杂量超过1％时，这会增加聚合物的表面张力，对于1.5％和2％气相二氧化硅掺杂，其表面张力分别为20.6和38.1 mN / m。
