Synthesis of PNIPAM Copolymer-Embedded Organic Nanotubes and Exploration of Their Adsorption and Release Performance towards MB and ARS
In order to efficiently adsorb dye molecules from dye wastewater,a novel adsorbent material with temperature controllability was prepared.Firstly,poly(N-isopropylacrylamide)(PNIPAM)was introduced into porous organic nanotubes via controlled free radical polymerization and ring-opening polymerization,resulting in multicomponent polymer brush with core-shell structure.Secondly,PNIPAM-modified multilevel porous organic nanotube network(MONNs)polymer with micro-,meso-and macroporous structures was synthesized through the grafting-to of the block copolymer and subsequent Fukui alkylation supper-cross-linking process.Finally,the adsorption and release properties of MONNs towards dye molecules methylene blue(MB)and alizarin red S(ARS)were explored.The results demonstrate that the MONNs materials prepared by this method have excellent adsorption efficiency towards dye molecules.
