Abstract Dynamics of dust mitigation from inclined hydrophilic/hydrophobic glass surfaces are examined after introducing the electrostatic repulsion. Glass surfaces are hydrophobized via coating by functionalized nano-silica particles. An electronic circuit and electrostatic plate were constructed to create electrostatic force mitigating the dust particles from the surface. A high speed recording system is used to track and record the motion of the inflight particles repelled from the surfaces. Adhesion of dust on the hydrophilic/hydrophobic glasses is assessed using the atomic force microscopy technique. The surface of the samples is tilted to monitor the influence of surface tilting on: i) dynamics of the inflight particles, ii) dust mitigation rate, iii) and optical characteristics of surfaces prior and after particle repelling. The findings reveal that hydrophobizing the sample surfaces reduces the particle adhesion on the sample surfaces and the force of adhesion remains larger for small particle (0.8 μm) than that of the large size particle (10 μm), which is because of the large interfacial force created between the low dimensional particles and the sample surface. The dust particle displacement alongside x, y, and x-axes increases for the hydrophobic surface onset of electrostatic excitation, which becomes more apparent for the tilted sample surfaces. Optical transmittance improves for the particle repelled from hydrophobic surfaces and it further improves as the surface tilting angle increases to 50°.

静电排斥作用下倾斜疏水和亲水表面的除尘

摘要 在引入静电排斥后，研究了倾斜亲水/疏水玻璃表面的除尘动力学。玻璃表面通过功能化纳米二氧化硅颗粒涂层进行疏水化处理。电子电路和静电板被构造成产生静电力，以减轻表面的灰尘颗粒。高速记录系统用于跟踪和记录从表面排斥的飞行粒子的运动。使用原子力显微镜技术评估亲水/疏水玻璃上灰尘的附着力。倾斜样品的表面以监测表面倾斜对以下方面的影响：i) 飞行中颗粒的动力学，ii) 灰尘缓解率，iii) 和颗粒排斥前后表面的光学特性。研究结果表明，对样品表面进行疏水化会降低颗粒在样品表面的粘附力，小颗粒（0.8 μm）的粘附力仍然大于大颗粒（10 μm）的粘附力，这是因为界面力大在低维粒子和样品表面之间产生。随着静电激发的疏水表面开始，沿 x、y 和 x 轴的尘埃粒子位移增加，这对于倾斜的样品表面变得更加明显。对于被疏水表面排斥的粒子，透光率提高，并且随着表面倾斜角增加到 50°，透光率进一步提高。8 μm) 比大尺寸颗粒 (10 μm) 大，这是因为低维颗粒和样品表面之间产生了很大的界面力。随着静电激发的疏水表面开始，沿 x、y 和 x 轴的尘埃粒子位移增加，这对于倾斜的样品表面变得更加明显。对于被疏水表面排斥的粒子，透光率提高，并且随着表面倾斜角增加到 50°，透光率进一步提高。8 μm) 比大尺寸颗粒 (10 μm) 大，这是因为低维颗粒和样品表面之间产生了很大的界面力。随着静电激发的疏水表面开始，沿 x、y 和 x 轴的尘埃粒子位移增加，这对于倾斜的样品表面变得更加明显。对于被疏水表面排斥的粒子，透光率提高，并且随着表面倾斜角增加到 50°，透光率进一步提高。这对于倾斜的样品表面变得更加明显。对于被疏水表面排斥的粒子，透光率提高，并且随着表面倾斜角增加到 50°，透光率进一步提高。这对于倾斜的样品表面变得更加明显。对于被疏水表面排斥的粒子，透光率提高，并且随着表面倾斜角增加到 50°，透光率进一步提高。
