A green Pickering emulsion stabilized by cellulose nanocrystals via RAFT polymerization


As environmental-friendly and renewable materials, cellulose nanocrystals (CNCs), has great potential for replacing the poisonous chemicals. Herein, we investigate a green Pickering emulsion stabilized of CNCs by using reversible addition-fragmentation chain transfer (RAFT) polymerization. The preparation of polymethyl methacrylate (PMMA) with controlled molecular weights and low M w/M n values were successfully synthesized by the Pickering emulsion. Moreover, the well-defined PMMA can be obtained in Pickering emulsion with “green” CNCs as a sole emulsifier and the used CNCs are easy to recycle and reuse.
