摘要： The current major way of making nanofibers is electrospinning. However, the minimum fiber diameter is limited to be about 300–500 nm, which is not compliant with the physical definition of nano structures (in the region of 1 to 100 nm). Futher, the productivity is relatively low. This invention provides a method for manufacturing a nano-sized di-block polymer including at least a hard-segment polymer and a soft-segment polymer. First, a sample containing the hard-segment polymer, the soft-segment polymer, and a catalyst is dissolved in a first solvent. Then the dissolved sample is cast on substrate, and then the first solvent to is removed form a dried sample. Finally, the nano-sized di-block polymer is formed by crew-cutting.
