A one‐pot method which involves peeling graphite nanosheets (GNs) off into graphenes in polymer solution and in situ forming polymer/graphene sheets nanocomposites by using ball milling is presented. Via this approach, nanocomposites based on maleic anhydride grafted poly (ethylene‐co‐vinyl acetate) (EVA‐g‐MAH) and graphene sheets comprising one to five layers were accomplished.

Ball milling is a simple but efficient approach for producing edge-functionalized graphene nanoplatelets. In a typical experiment, graphite powders are mixed with chemicals containing heteroatoms (e.g. dry ice [ 14 ], sulfur xide [ 15 ], melamine [ 16, 17 ], polystyrene [ 18 ]) in a sealed jar, followed by high speed ball milling.

We report the rapid amorphization of the prototypical substituted zeolitic imidazolate framework, ZIF-8, by ball-milling. The resultant amorphous ZIF-8 (amZIF-8) possesses a continuous random network (CRN) topology with a higher density and a lower porosity than its crystalline counterpart.

Dry ball milling of graphite with cellulose and related polysaccharides was found effective for exfoliation-dispersion of graphene-like carbon. The exfoliation behavior was found to depend strongly on the polymer species; namely, polysaccharides are much more effective than thermoplastic polymers. The compression-molded slabs from co-milled powder with cellulose and carboxymethylcellulose ...

The influences of milling time and process control agents on the preparation of ultrafine nickel powder were studied systematically by granularity test,SEM and XRD.The results show that: with increasing milling time,the nickel powder particle size decreases rapidly at first and then the particle size changes slightly,the nickel powder can milling effectively by adding process control agent KH ...

The MgB 2 tape with the ball-milling treatment exhibited a dense and uniform microstructure mainly composed of nano-crystalline MgB 2 . On the other hand, MgB₂ tapes without the ball-milling treatment showed inhomogeneous microstructures that comprise of a porous uncrystallized area and a crystallized one.

As shown in Fig. 1, ball milling effectively increased adsorption capacity from 5–15 mg/g for unmilled biochars to 100–300 mg/g for BM–biochars (about a 20-fold increase) regardless of different feedstock type and pyrolysis temperature.Both biochar feedstock type and pyrolysis temperature showed strong influence on capacity. For the same feedstock, removal increased in the order ...

The ball mill machine (NanDa Instrument Plant, Nanjing, China) was operated at 500 rpm with rotation direction changed every 0.5 h. The ball milling time and weight ratio of biochar to milling ball, two important milling parameters, were further investigated to address the effects of ball milling on biochar sorption for NSAIDs.

We have synthesized pure nanocrystalline CeO ₂ powders of nearly spherical shape using high-energy attritor ball mill. Milling parameters such as the milling speed of 400rpm, ball to powder ratio (40:1), milling time (30h) and water cooled media were determined to be suitable for synthesizing nanosize (∼10nm) powders of CeO ₂ . The powders after milling for various ...
