DUST COLLECTING FILTER FOR PRINTER HAVING CARBON NANOTUBES-CHITOSAN MEMBRANE, FILTERING SYSTEM COMPRISING THE SAME AND PRINTER HAVING THE SAME

摘要

PURPOSE: A dust collecting filter for a printer including a carbon nanotube-chitosan membrane, and a filtering system and a printer including the dust collecting filter are provided to effectively collect minute particles produced from a printer using the carbon nanotube-chitosan membrane and an electric field. CONSTITUTION: A dust collecting filter for a printer comprises a fixed member(110), a carbon nanotube-chitosan membrane(130), and an electrode(120). The carbon nanotube-chitosan membrane is formed of carbon nanotube and chitosan composition and placed in the fixed member. The electrode supplies power to the carbon nanotube-chitosan membrane.
