Synthesis of Well-Defined Polymer Brushes Grafted onto Silica Nanoparticles via Surface Reversible Addition-Fragmentation Chain Transfer Polymerization
Reversible addition-fragmentation chain transfer polymerization (RAFT) was used to prepare polymer brushes grafted onto silica nanoparticles. Novel RAFT-silane agents were prepared that contained both an active RAFT moiety and a silane coupling agent. RAFT agents were anchored to silica nanoparticles by the functionalization of colloidal silica with the RAFT-silane agents. RAFT polymerizations ...

In this paper, a series of well-defined polyethylene-b-polytetrafluoroethylene diblock copolymers (PE–b– PTFEs) were prepared by a coupling reaction of hydroxyl-terminated polyethylene (PE–OH) and isocyanateterminated 1H,1H-perfluoro-1-tetradecanol (PFDO–NCO). PE–OH was prepared by the coordination chain transfer polymerization using 2,6-bis[1-(2,6-diisopropylphenyl)imino ethyl] pyridine iron (...

ReceiVed January 17, 2008 ReVised Manuscript ReceiVed February 21, 2008 Introduction. In recent years, much attention is paid to the synthesis of copolymers with different compositions and chain architectures, such as linear, grafted, comb-shaped, star-shaped, hyperbranched, and dendrimeric chains with the purpose to establish architecture-property relationships in bulk and in solution. Of thes...
متن کاملFacile synthesis of V-shaped copolymer brushes grafted onto the surface of graphene oxide via coupling reactions.
Mid-functionalized ABC triblock copolymers with a short central B block were synthesized via the RAFT process, and further used as well-defined V-shaped copolymers to graft onto graphene oxide by coupling reactions.
متن کاملEnzymatic synthesis of organic-polymer-grafted DNA.
To create bioorganic hybrid materials, interdisciplinary work in the fields of chemistry, biology and materials science is conducted. DNA block copolymers are promising hybrid materials due to the combination of properties intrinsic to both the polymer and the nucleic acid blocks. Until now, the coupling of DNA and organic polymers has been exercised post-synthetically in solution or on solid s...
