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.

摘要： This invention relates to melt extruded latent contractable elastic filaments which are formed by melt extruding certain segmented crosslinked thermoplastic polymers to form filaments, which filaments, when heat processed at elevated temperatures, significantly contract to yield an elastic filament. This invention also relates to the formation of composite covered yarn comprising said latent contractable melt extruded filaments. In addition, this invention relates to processes for forming articles from said latent contractable filaments or covered yarns comprising said contractable filaments and subsequently contracting said yarns to form an elastic article.

摘要： A method for producing ceramic fibers of a composition in the SiC range, starts from a spinning material that contains a polysilane-polycarbosilane copolymer solution. The spinning material is extruded through spinnerets in a dry spinning method and spun through a spinning duct into green fibers, and the green fibers are subsequently pyrolyzed. Accordingly, the polysilane-polycarbosilane solution contains between 75 wt. % and 95 wt. %, in particular between 80 and 90 wt. %, of an indifferent solvent, and the spinnerets have a capillary diameter between 20 and 70 μm, in particular between 30 and 60 μm, in particular between 40 and 50 μm.
