The MAC generates negative air ions with the aid of carbon nanotube discharge in air. The electric conductivity and the nanoscale tip of carbon nanotube cause the electron discharge easily. Therefore the characteristics of the MAC are microscale size, low discharge voltage, and personal usage. The negative air ions generated by MAC are radicals with chemical reactivity and negative charge. The negative air ions can react with the air pollutants, and charge the aerosols and bioaerosols for air cleaning. The partially air around the MAC will be clean by the negative air ions from MAC. Moreover, the MAC enhances the filtration efficiency of mask around the MAC. This study includes three topics for three years. In first one year, the MAC will be developed and tested. In second year, the removal efficiency and the zone in effect of different aerosols with the aid of MAC will be studied. In third year, the removal efficiency and the zone in effect of different bioaerosols with the aid of MAC will be studied.空氣負離子奈米碳管尖端放電微型空氣清淨設備Negative air ionCarbon nanotubeElectric dischargeMicroscale air ionizer
