Electrospinning is a versatile and easy technique for preparing nanofiber mats. Nanofibers have exciting
a new class of material which used for a wide range of applications from medical to consumer products such as,
filtration, wound dressing, adsorbent, energy storage, protein separation, immobilization, drug delivery and
composites. The main features of nanofibers are large surface area–to-volume ratio, good mechanical, strength,
excellent flexibility, and high porosity. These properties make them suitable for many applications. Starch is
among the most abundant and inexpensive biopolymers. Starch forms esters with organic and inorganic molecules.
Starch esters are interesting because of its starch properties which can be modified and its application enlarged by
introducing different side groups into the starch molecule. Starch has limited-applications because of its low shear–
stress resistance and thermal decomposition. Therefore, in order to enhance the properties of starch, they are
modified by various modification methods [1, 2].
In this study, thermally cross-linked starch/poly(ethylene- alt-maleic anhydride) electrospun mats were
prepared. Electrospinning solutions were prepared by mixing starch and certain amounts of poly(ethylene-alt-
maleic anhydride). Starch-based nanofiber mats became insoluble in water with thermal-induced esterification of
hydroxyl groups onto starch backbone. Morphologic and structure analysis as well as thermal properties of starch
/ poly(ethylene- alt-maleic anhydride) of composite nanofibers were investigated by Scanning electron microscopy
(SEM), Fourier transform infrared (FTIR) spectroscopy and Thermogravimetric analyses (TGA).
