纳米羟基磷灰石/玉米醇溶蛋白-聚乳酸-乙醇酸共聚物皮芯结构复合纳米纤维膜的制备及性能
Preparation and Properties of Nano-Hydroxyapatite/Zein-Poly (lactide-co-glycolide) Shell-core Structured Composite Nanofibrous Membranes
本文通过同轴静电纺丝法制备出纳米羟基磷灰石（nHA）/玉米醇溶蛋白（zein）-聚乳酸-乙醇酸共聚物（PLGA）皮芯结构复合纳米纤维膜。用场发射扫描电镜（FE-SEM）、透射电镜（TEM）、红外光谱仪（FT-IR）、X射线衍射仪（XRD）、接触角测量仪及多功能拉伸仪对复合纳米纤维膜的形貌、结构、性能进行表征和测试。结果表明，当PLGA含量小于50%时，纤维的皮芯结构明显；随着PLGA含量的增加，纤维直径增大；PLGA的加入不影响（nHA/zein）的分子结构和nHA的晶体结构，但会降低纤维膜亲水性；当PLGA含量为30%，复合纳米纤维膜的拉伸破坏应力最大。
Nano-hydroxyapatite (nHA)/zein-poly(lactide-co-glycolide) (PLGA) shell-core structured composite nanofibrous membranes were prepared via coaxial electrospinning. The morphology, structure and properties of composite nanofibrous membranes were characterized and tested by use of FE-SEM, TEM, ATR-FTIR, XRD, contact angle measurement and tensile tester. The results show that shell-core structure is obvious when the PLGA content lower than 50%. With increasing PLGA content in the shell-core structured composite nanofibers, the diameter of the fibers increases. The addition of PLGA has no influence on the molecular structure of (nHA/zein) and the crystal structure of nHA, but decreases the hydrophilicity of the nanofibrous membranes. The tensile strength of composite nanofibrous membranes is highest when the PLGA content is 30%.
