Copper on chitosan-modified cellulose filter paper as an efficient dip catalyst for ATRP of MMA

Abstract Achieving an efficient catalyst in the ATRP system with a simple design, preparation from available materials, and high recyclability is a significant challenging issue. To attain the goal, herein, we used chitosan (CS)-modified cellulose filter paper (FP) as a green support for the synthes...
