Title Characterization and control of airborne particles emitted during production of epoxy/carbon nanotube nanocomposites
Bibliographic information Feb. 2011, Vol.8, p.86-92. Illus. 24 ref.
Abstract The objective of this study was to characterize airborne particles generated from the weighing of bulk, multiwall carbon nanotubes (CNTs) and the manual sanding of epoxy test samples reinforced with CNTs. It also involved the evaluation of the effectiveness of three local exhaust ventilation (LEV) conditions (no LEV, custom fume hood, and biosafety cabinet) for control of particles generated during sanding of CNT-epoxy nanocomposites. Particle number and respirable mass concentrations were measured using an optical particle counter (OPC) and a condensation particle counter (CPC), and particle morphology was assessed by transmission electron microscopy. Findings are discussed.
