Synthesis of Functional Poly (divinylbenzene) Nanoparticles by Inter-block RAFT Polymerization |
초록 |
An efficient synthetic method of stable nanoparticles with PEO functionalities on the core surface was developed and one advantage of this method is that the micellization and cross-linking reactions occur in one pot, forming stable nanoparticles with functional surfaces. First, amphiphilic PEO-b-PS copolymers were synthesized by RAFT polymerization of styrene using PEO-based trithiocarbonate as macro-RAFT agent. The low molecular weight PEO-b-PS copolymer was dissolved in isopropyl alcohol where the block copolymer self-assembled as core-shell micelles, and then the core-shell interface cross-link was performed using DVB as a cross-linking agent and AIBN as an initiator. Design of the amphiphilic RAFT agent is found to be critical for the successful preparation of core-shell interface cross-linked micelle nanoparticles, because RAFT functional group inter-connects PEO and polystyrene block. The PEO functionality of the nanoparticles surface was confirmed by 1H-NMR and FT-IR. |
