The COVID-19 pandemic has caused a high demand for filtering facepiece respirators (FFRs), which has brought global challenges in sustaining the supply chain for FFRs. Because respirators are basic personal protective equipment to protect f...
Effects of surface charge and environmental factors on the electrostatic interaction of fiber with virus-like particle: A case of coronavirus [0.03%]
表面电荷和环境因素对纤维与类病毒粒子静电作用的影响：以冠状病毒为例
D N Dung,Anh D Phan,Toan T Nguyen et al.
D N Dung et al.
We propose a theoretical model to elucidate intermolecular electrostatic interactions between a virus and a substrate. Our model treats the virus as a homogeneous particle having surface charge and the polymer fiber of the respirator as a c...
