Two standard nanoparticle production systems are used: 'top-down' and 'bottom-up'. 'Top-down' refers to the physical crushing of source material using a milling system. 'Bottom-up' strategies build particles via chemical operations. Choosing a method should be determined by the chemical makeup and the features chosen for the nanoparticles.
Ball milling of graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimeter-sized metal balls causing exfoliation to graphene (Fig. 2.5), under wet or dry conditions.For instance, this method can be employed to produce nearly 50 g of graphene in the absence of any oxidant. 22 Graphite (50 g) was ground in ...
High-energy ball milling is effective in getting well-dispersed slurry. 7−9 The preparation procedure is summarized in Fig. 24.2.First, commercially available PZT powders ( 850) were high-energy ball milled to get the desired particle size. Secondly, a selected dispersant was added to the milled powders to get the surface-modified powders.
