DOI: 10.1007/s00396-020-04770-w
Abstract: Deep eutectic solvents (DES) have revealed the ability to promote the aggregation of amphiphiles in solution. With a brief overview on the self-assembly of amphiphilic substances in protic/aprotic, polar/non-polar solvents, ionic liquids (ILs), and deep… read more here.

DOI: 10.1021/acs.macromol.8b00744
Abstract: Heteroarm star-graft block quarterpolymers [PSn(P2VP-b-PAA-g-PNIPAM)n] with pH-sensitive weak polycationic/polyanionic arms and grafted thermoresponsive outer chains are integrated into hydrogen-bonded multilayers with morphologies distinct from those in traditional layer-by-layer assemblies. We discovered that block-specific swelling promotes… read more here.

Abstract: Linear and star block copolymer (BCP) nanoassemblies of [poly(4-vinylpyridine)-block-polystyrene]n ([P4VP-b-PS]n) with different arm numbers have been synthesized by RAFT dispersion polymerization under formulation of polymerization-induced self-assembly (PISA). All RAFT dispersion polymerizations employing mono- and multifunctional… read more here.
