Eudragit S100/β-cyclodextrin nanofibers by electrospinning
摘要
Abstract
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.关键词
