摘要：
The development of metal-free photoinduced electron transfer-atom transfer radical polymerization (PET-ATRP) in Pickering emulsion by cellulose nanocrystals (CNCs) has successfully investigated. In the presence of ethyl 2-bromoisobutyrate (initiator) and triethylamine (additives), Eosin Y (photocatalyst) can effectively achieve the controllable polymerization of methyl methacrylate utilize CNCs as stabilizer. The polymerization in Pickering emulsion has relatively higher stability. The polymerizations of MMA showed typical living/controlled characteristics with controlled molecular weights (150,100-219,100g/mol) and low M-w/M-n (1.10-1.25). CNCs can not only be recycled, but also can be applicable as one of the most robust green emulsifier for PET-ATRP in Pickering emulsion. [GRAPHICS] .
