| 中文摘要 | a series of biodegradable, thermoplastic polyurethane elastomers poly (epsilon-caprolactone-co-lactide)polyurethane [pcla-pu] were synthesized from a random copolymer of l-lactide (la) and epsilon-caprolactone (cl), hexamethylene diisocyanate, and 1,4-butanediol. the effects of the la/cl monomer ratio and hard-segment content on the thermal and mechanical properties of pcla-pus were investigated. gel permeation chromatography, ir, c-13 nmr, and x-ray diffraction were used to confirm the formation and structure of pcla-pus. through differential scanning calorimetry, tensile testing, and tensile-recovery testing, their thermal and mechanical properties were characterized. their glass-transition temperatures were below -8 degrees c, and their soft domains became amorphous as the la content increased. they displayed excellent mechanical properties, such as a tensile strength as high as 38 mpa, a tensile modulus as low as 10 mpa, and an elongation at break of 1300%. therefore, they could find applications in biomedical fields, such as soft-tissue engineering and artificial skin. |
