Subsequently, the ballgrinding tanks were loaded onto the planetary ball mill, and the ballmilling process was performed at a speed of 500 r/min for 8 h at room temperature. After this, the BN powders in mixed solution were collected by vacuum filtration, and washed three times with deionized water to remove the unreacted KH550 molecules.

As stated earlier, epoxy based thermoset nanocomposites with HNT nanofillers were prepared by insitu photoinitiated cationic polymerization at room temperature in this work. Successful functionalization was confirmed by FTIR spectroscopy (Fig. S1).Thus, the presence of epoxy moieties was verified from the presence of C O C (790 cm −1) and aliphatic C H (2930 cm −1) bands of glycidyl ...

Effects of ball milling on biochar's physicochemical Increase of surface area. The specific surface area of the BMbiochars were all greater than that of their precursors (corresponding unmilled biochars, Table 1).The unmilled biochars produced at 300 °C had very low surface area (02 m 2 /g), which is common for biochars produced at low temperatures (Guo and Chen, 2014).

There has been an increase in interest in developing functional polymer composites based on green chemistry principles. The purpose of this study was to investigate the preparation of functional epoxy/carbon nanotube nanocomposites using ball milling methods. In contrast to mechanical mixing, ball milling promoted good dispersion of CNTs within the epoxy matrix, thereby improving their ...

4 nanocomposites. The pure powders were carefully mixed with the required amount of silicon nitride (0,, vol%). The mixing process was performed at room temperature using a Retsch PM400 planetary ball mill for 2 h at the milling speed set at 200 rpm in order to get a homogeneous particle distribution. No balls were used in this stage.

As previously stated, the MA process is a method where the elemental metal powders are repeatedly fracturing and rewelding in a high energy ball mill. In the MD process, however, the starting feedstock materials are intermetallic alloys, so that these crystalline alloys tend to convert into an amorphous solid state by relaxing the shortrange order without compositional alterations [ 24 ].
