Abstract

There is an increasing interest to fabricate natural nanofibers with tunable structures using electrospinning. Pectin (PEC), an anionic hetero-polysaccharide present in plant cell-walls, is biodegradable and biocompatible so it can be used in biomedicine and food industry. In this study, various blends of pectin and polyethylene oxide (PEO) solutions were prepared. The viscosities of the samples containing Triton-X-100, as a nonionic surfactant, were measured prior to electrospinning. The electrospinning parameters, PEC: PEO ratio and molecular weight (Mw) of PEO were assessed using SEM, and ATIR-FTIR spectroscopy in order to improve the spinnability of pectin with appropriate morphological appearance and mechanical properties. SEM micrographs implied that higher Mw of PEO is a feasible way to apply higher ratio of PEC: PEO, leading to bead-free fiber formation. In addition, it was also found that higher ratio of PEC: PEO resulted in thinner nanofibers.
