Block eopolymers （BCs） have become a hot topic in the research field of materials science, polymer science and biologi- cal science because of their unique structure and properties. In this review, the preparation methods of BCs developed in recent years have been summarized, including anionic polymerization, nitroxide^mediated polymerization （NMP）, atom transfer radical polymerization （ATRP）, and reversible addition-fragmentation chain transfer polymerization （RAFT）. The nanocomposite prep- aration methods using BCs as templates, and those methods used to control the micro morphology of the nanocomposites, are also summarized. Finally, the challenges and future development of the field are overviewed.
