摘要：

Diblock copolymers containing polythiophenes was synthesized by using the living radical polymerization techniques such as reversible additional fragmentation chain transfer polymerization (RAFT) and nitroxide mediated polymerization (NMP) to make rrPT-polyisoprenes and rrPT-polystyrenes. Surface morphology studies of polymer films visualized with tapping mode atomic force microscopy (TMAFM) shows that the conductivities of ply(3-hexylthiophene) precursors are higher than the dioblock copolymers. The results also show that the conductivity of the diblock copolymer decreases with the increase of the content of the nonconducting block. The resulting copolymers are found to be soluble in various organic solvents and possess excellent film forming properties. The nonconductive polymer blocks assume different structures and a range of vibrational molecular weights and compositions.
