Apr 29, 2011· Obtaining nanoparticles of ZnO in this size (30 nm) is a remarkable result, maybe due to the use of the high-energy ball milling technique. Other investigators have reported 41, 43 that when the particles become small enough (typically hundreds of nm), further refinement cannot be observed due to equilibration of cold welding and fracturing.
Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.
Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.
ally takes a very long time to obtain nanoparticles with low-energy surfactant-assisted ballmilling[22]; therefore the high-energy ball milling (HEBM) is typically used when dealing with materials as reactive as RE–TM. Use of surfactants during ball milling is known to influence not only the size of the particles, but also their shape.
