Abstract: The solid state morphology of the tri-block copolymer PS-b-PCEMA-b-PtBA, which was synthesized by anionic polymerization with narrow molecular weight distribution, was in lamella structure from TEM micrographs. After being blended with polystyrene with the mass ratio of 1:04, the morphology showed cylinder structure. With PSas continous phase, PCEMA and PtBA phases formed cylinders with PCEMA as outer layer. The nanofibres can be got and dispersed in good solvents of PS when the PCEMA phase was crosslinked. The t-butyl group in PtBA phase can be cleavaged by reacting with TM-SI, and nanofibres changed to nanotubes finally. It has the great potential applications, such as in the preparation of nanowires, template polymerization, nano reactor etc ..

Key words: Block copolymer, Solid morphology structure, Nanofibre, Hollow nanofibre
