Speech Tilte: Nanofiber Filters for Efficient Air Pollution Control
Indoor air quality is essential to public health as people spend most of their time indoors. Heavy outdoor air pollution, especially particulate matters (PM), has significantly impacted the living quality of residential environments. Consequently, it is crucial to mitigate indoor PM to improve indoor air quality and reduce the associated health risks. High efficiency particulate air (HEPA) filters can be installed in the heating, ventilation, and air-conditioning (HVAC) systems to remove PM from the incoming outdoor air. Although HEPA filters exhibit high particle removal efficiency, they usually lead to a large pressure drop, which may increase the energy consumption in HVAC systems. In contrast to the HEPA filters, electrospun nanofiber filters can offer high particle filtration efficiency with relatively low pressure drop. In this talk, the filtration performance of the nanofiber filter for energy conservation and air pollution control would be enhanced based on three aspects, such as experimental and modeling study of filtration performance across nanofiber air filters, development of functional composite nanofiber filters, and developing facile strategies for effective control of air pollution.
Ye Bian received a PhD degree from the Chinese University of Hong Kong, and held a postdoctoral fellow position in the same institution. Now, he is an associate professor in School of Energy and Environment at Southeast University. His research interests include functional nanofiber membranes fabrication and application in energy conservation and air pollution control (such as PM2.5, ultrafine particles, formaldehyde, etc). So far, he has been participated in the publication in Nano Energy, Journal of Materials Chemistry A, Building and Environment, Applied Materials Today, Indoor Air, Energy and Building, ACS Applied Materials & Interfaces, etc.
