报告摘要：

Polymerisation-induced self-assembly (PISA) is a highly versatile, potentially scalable platform technology that enables the efficient and rational synthesis of block copolymer nanoparticles of various morphologies directly in the form of concentrated dispersions. The basic principles of PISA are generic: a wide range of diblock copolymer nano-objects can be readily prepared in either water, ethanol or n-alkanes. In PISA, a soluble precursor 'A' block is chain-extended using a second monomer that forms an insoluble 'B' block in the chosen solvent. As this second 'B' block grows in the monomer/solvent reaction mixture, micellar nucleation occurs at some critical chain length, leading to the formation of sterically-stabilized nanoparticles. Depending on the relative volume fractions of the 'A' and 'B' blocks, the copolymer morphology can be either spheres, worms or vesicles.

This talk will focus mainly on the RAFT aqueous dispersion polymerisation of 2-hydroxypropyl methacrylate (HPMA), which serves as a convenient model system for understanding PISA formulations.
