Controlling nanomaterial synthesis, chemical reactions and self assembly in dynamic thin films

Recent advances in continuous-flow processors, which integrate sustainability metrics including scalability, have established their utility in materials and chemical processing. In this review the spinning disc processor (SDP) and the related rotating tube processor (RTP), are highlighted in the use of highly sheared and micro-mixed dynamic thin films in gaining control over such processing for a wide range of applications. Both SDP and RTP have a number of control parameters beyond traditional batch processing which are effective in (i) manipulating the size, shape, defects, agglomeration, and precipitation of nanoparticles, as well as decorating preformed nano-structures, for a variety of inorganic and organic compounds, (ii) controlling chemical reactivity and selectivity including the formation of polymers, and (iii) disassembling self organised nano-structures, as a tool for probing macromolecular structure under shear conditions. © 2014 The Royal Society of Chemistry.
