The relation between the surface limiting elasticity modulus, ε₀, of difenoconazole-loaded mesoporous silica nanoparticle (DF-MSN) formulations with associated SDS and the height of the first returning droplet impacting on cabbage and rice leaf surfaces was investigated. The surface dilational rheology properties were determined by means of surface tension relaxation. The impact of a droplet on the leaf surface was recorded with a high-speed camera. The surface limiting elasticity modulus, ε₀, shows differences with different SDS concentrations. A positive correlation between droplet first rebound height and the surface limiting elasticity modulus, ε₀, is observed. The pesticide droplet impact on the target leaf surface is a rather complex phenomenon, so the focus of this article is to establish a relationship between the surface limiting elasticity modulus, ε₀, and droplet first rebound height. These findings introduce a chemical way to affect the impact behavior of pesticide droplets on target crop leaf surfaces, which may be of particular importance for pesticide spraying and crop protection, especially for hydrophobic and superhydrophobic target crops.

表面极限弹性模量对带有联用SDS的负载二苯并氟康唑的中孔二氧化硅纳米颗粒液滴的冲击行为的影响

表面限制弹性率之间的关系，ε ₀，醚唑加载孔二氧化硅纳米颗粒（DF-MSN）相关联SDS制剂和对卷心菜和稻叶表面第1返回液滴冲击的高度进行了研究。通过表面张力松弛来测定表面膨胀流变性质。用高速照相机记录液滴对叶片表面的影响。表面限制弹性模量，ε ₀，示出了具有不同浓度的SDS的差异。液滴第一反弹高度和表面限定弹性模之间的正相关关系，ε ₀，被观察到。目标叶表面上的农药液滴冲击是一个相当复杂的现象，所以本文的重点是建立表面限制弹性模之间的关系，ε ₀，和液滴第一反弹高度。这些发现引入了一种化学方法来影响农药液滴对目标作物叶片表面的影响行为，这对于农药喷洒和作物保护（尤其是疏水和超疏水目标作物）尤其重要。
