摘要： Shape-memory polymer is a new kind of material utilizing shape memorizing mechanism of elastomer of polyurethane family. These materials exhibit novel properties such as sensing (thermal), actuaton, high damping, adaptive responses, super-elasticity capability and air permeability. Recently, they are used and applied to finish textiles and garments. Although there are some characterization methods for shape memory polymers, there is currently no characterization method to evaluate the effects of shape memory fabrics. This invention provides a method to determine the shape memory coefficient of fabrics. The fabric is first deformed from the original state to a deformed state and then subjected to a switch temperature. Different parameters are measured at the original state before and after the fabric is subjected to the switch temperature to determine the shape memory coefficient.

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.
