| 中文摘要 | a series of biodegradable polyurethanes (pus) are synthesized from the copolymer diols prepared from l-lactide and epsilon-caprolactone (cl), 2,4-toluene diisocyanate, and 1,4-butanediol. their thermal and mechanical properties are characterized via ftir, dsc, and tensile tests. their t(g)s are in the range of 28-53 degrees c. they have high modulus, tensile strength, and elongation ratio at break. with increasing cl content, the pu changes from semicrystalline to completely amorphous. thermal mechanical analysis is used to determine their shape-memory property. when they are deformed and fixed at proper temperatures, their shape-recovery is almost complete for a tensile elongation of 150% or a compression of 2-folds. by changing the content of cl and the hard-to-soft ratio, their t(g)s and their shape-recovery temperature can be adjusted. therefore, they may find wide applications. |
