我们发现，纳米级水毛细桥（WCB）之间形成的斑片状表面可以从环境中提取能量时，受到相对湿度（RH）的变化。我们的研究结果是基于分子动力学模拟结合修改后的版本的拉普拉斯-开尔文方程，这是使用纳米级WCB验证。纳米级WCB收获的计算能量密度是相关的，约1700 kJ/m3，并且与使用由于RH变化而膨胀和收缩的可用水响应材料收获的能量密度相当。
We show that nanoscale water capillary bridges (WCB) formed between patchy surfaces can extract energy from the environment when subjected to changes in relative humidity (RH). Our results are based on molecular dynamics simulations combined with a modified version of the Laplace–Kelvin equation, which is validated using the nanoscale WCB. The calculated energy density harvested by the nanoscale WCB is relevant, ≈1700 kJ/m3, and is comparable to the energy densities harvested using available water-responsive materials that expand and contract due to changes in RH.
