Functional materials such as luminescent polymers can have applications, e.g., in organic lasers, solar cells, sensors, or bioimaging. However, the preparation of these polymers often requires multi-step chemical syntheses. Ball milling of synthetic polymers causes breaks in the polymer chain and generates free radicals known as mechanoradicals, which could be …


Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear …


High energy ball milling (HEBM) is a relatively modern technique which is used mainly to incorporate nanoparticles into polymer matrices. Many studies have shown that HEBM prior to the final processing not only improves mixing and filler dispersion, but also leads to composites with better properties at lower filler content [1–6].Very few studies, however, have focused on …

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
