Mechanochemical milling

The solid-state mechanochemical milling using a pan mill was employed to devulcanize GRT (Xu et al., 1996). A decrease of the gel fraction and crosslink... 

The solid-state mechanochemical milling of PP/GRT blends was carried out, leading to the improved dispersion, as confirmed by the fluorescence microscopy and polarized optical microscopy (POM) observations (Zhang et al., 2012b). After 20 cycles of milling, the tensile strength and elongation at break of PP/GRT blends at a ratio of 100/40 were increased by 13.8% and...

Because of its high sensitivity, EPR was used recently to measure the quantity of energy used locally during a mechanochemical milling process.

Figure 12 Illustration of the dynamic nature of coordination polymers and open MOFs under mechanochemical milling conditions. Millmg with a suitable liquid phase leads to the formation of different open- and close-packed materials based on zinc terephthalate. Such high level of structural dynamics is not observed in analogous slurry experiments...

A solid-state mechanochemical milling process has been developed that combines both the devulcanisation of tyre waste and its mixing into an HDPE matrix [23]. The resulting product was also dynamically vulcanised within the mill, resulting in a thermoplastic elastomer (TPE) that SEM analysis showed to have good interfacial compatibility between the rubber and thermoplastic phases.
