▎ 摘　　要

NOVELTY - An assembly comprises a substrate, a graphite solution, where the substrate is treated with the graphite solution, and an ionizer (204) to apply a static charge to the substrate by ionizing particles. USE - Assembly used in air filtration unit and automobile ventilation unit for attracting and neutralizing contaminants from air (all claimed). ADVANTAGE - The assembly ensures pathogen-free air, and suppressed clogging thereby not affecting the performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the assembly, which involves mixing graphite powder with an acid and a binder, stirring the mixture to exfoliate it into amorphous particle fullerene graphene structures, and applying the mixture to the substrate; (2) an air filter unit, which comprises the assembly; (3) an automobile ventilation unit; and (4) use of the assembly for attracting and neutralizing contaminants from air. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of assembly. Graphite coating (201) Electrodes (202, 203) Ionizer (204) Foam (206)
