POLYMERISATION-INDUCED SELF-ASSEMBLY
VIA RAFT DISPERSION POLYMERISATION
Prof. Steven P. Armes
Department of Chemistry, University of Sheffield, Brook Hill, Sheffield, Yorkshire, S3 7HF, UK.
The efficient, reproducible synthesis of bespoke organic nanoparticles of controlled size, morphology and surface functionality in concentrated solution is widely regarded to be a formidable technical challenge. However, we have recently demonstrated that polymerisation-induced self-assembly (PISA) is a highly versatile, potentially scalable platform technology that allows substantial progress to be made towards addressing this important problem.1-17 The basic principles of PISA are generic: a wide range of diblock copolymer nano-objects (spheres, worms or vesicles) can be readily prepared in either aqueous solution, ethanol or n-alkanes. In collaboration with industrial partners, various applications are being explored for this platform technology at U. Sheffield, including long-term storage media for stem cells.14 Selected PISA formulations for both water and n-alkanes will be discussed in this lecture. Characterisation of the in situ evolution in copolymer morphology during PISA using synchrotron SAXS will also be highlighted.
