利用静电纺丝法成功制备了尤特奇S100/β-环糊精(ES100/β-CD)纳米纤维.通过对纺丝条件的优化,从ES100佃.CD混合溶液中纺丝得到了表面光滑、分布均匀的圆柱状纳米纤维.研究结果发现,当ES100浓度较高时,β-CD在混合溶液中的浓度从2%逐渐增加至20%(w/w,以ES100为基准)均可得到无液珠的纳米纤维.在较低的ES100溶液浓度下,β-CD的加入有利于得到表面光滑的纳米纤维,纤维的平均直径随着卢-CD含量的增加而增大.红外光谱(FTIR)结果证实了所得纳米纤维中卢一CD的存在,ES100/β-CD的粉末X-射线衍射(XRD)光谱图中没有明显的衍射峰,说明β-CD分子在纳米纤维中分布均匀,没有形成结晶体和包合物.所制备的β-CD功能化的纳米纤维在药物输送系统和污水处理领域具有广泛的应用前景.

Eudragit S100/β-cyclodextrin (ES100/β-CD) nanofibers were successfully produced by electrospinning technique with the goal to develop functional nanowebs. Bead-free uniform electrospun ES100/β--CD nanofibers were obtained from homogeneous blend solutions of ESIOO/β-CD by optimizing the electrospinning conditions. The concentration of β-CD in the blend solution was varied from 2 % up to 20 % (w/w, with respect to the ES100 matrix). It is found that the presence of β-CD in the ESIO0 solutions facilitates the electrospinning of bead-free nanofibers from the lower polymer concentrations, and the fiber diameter increased with the i.ncrease of β-CD content. Fourier transform infrared (FTIR) studies elucidate that β-CD molecules are presented in the nanowebs. The X-ray diffraction (XRD) spectra of ES100 /β-CD nanowebs did not show any significant diffraction peaks indicating that the β--CD molecules are homogeneously distributed within the ES100 matrix and does not form any phase separated crystalline aggregates. The β-CD functionalized nanowebs may have the potential to be used in waste treatment and drug delivery system.
