Electrospun nanofibers mats are green synthesized using hydroxypropyl cellulose (HPC) individually or in conjugation with either poly(vinyl alcohol) (PVA) or Polyvinylpyrrolidone (PVP) to enhance the mechanical properties of the nanofibers mats. Desirable attributes of the as-obtained nanofibers mats are manifested via using SEM, FT-IR, TGA and conventional tools for mechanical and physical properties. The obtained data from SEM images demonstrated that the diclofenac sodium (DS) loaded nanofibers mats did not provide significant change of the morphological structure to the mats. In addition the thermal stability and the visual and mechanical properties of PVA or PVP was dramatically enhanced with the addition of HPC. The in vitro sustained release of DS drug was controlled when loaded into electrospun nanofibers of HPC with either PVA or PVP.
静电纺纳米纤维垫通过单独使用羟丙基纤维素(HPC)或与聚乙烯醇(PVA)或聚乙烯吡咯烷酮(PVP)结合进行绿色合成,以增强纳米纤维垫的机械性能。通过扫描电子显微镜(SEM)、傅里叶变换红外光谱(FT-IR)、热重分析(TGA)以及用于机械和物理性能的传统工具来体现所得纳米纤维垫的理想特性。从SEM图像获得的数据表明,负载双氯芬酸钠(DS)的纳米纤维垫对垫的形态结构没有产生显著变化。此外,加入HPC后,PVA或PVP的热稳定性以及视觉和机械性能得到显著提高。当DS药物负载到HPC与PVA或PVP的静电纺纳米纤维中时,其体外缓释得到控制。
