热等离子体效应显著提高了真空膜蒸馏的效率，这是一种经济上可持续的高质量海水淡化工具。使用填充有球形银纳米颗粒的聚偏二氟乙烯（PVDF）膜，其尺寸针对目标进行了调整。在膜中加入等离子体纳米粒子后，跨膜通量增加了11倍，而且膜界面的温度高于体相温度。
Thermoplasmonic effects notably improve the efficiency of vacuum membrane distillation, an economically sustainable tool for high-quality seawater desalination. Poly(vinylidene fluoride) (PVDF) membranes filled with spherical silver nanoparticles are used, whose size is tuned for the aim. With the addition of plasmonic nanoparticles in the membrane, the transmembrane flux increases by 11 times, and, moreover, the temperature at the membrane interface is higher than bulk temperature.
