High-amylose starch can dissolve effectively in a room temperature ionic liquid 1-allyl-3-methylimidazolium chloride (amimCl). By using amimCl as the reaction medium
high-amylose starch acetates with a relatively wide range of degree of substitution (DS) were homogeneously synthesized by a one-step method in the absence of any catalyst.The effects of reaction time and acetic anhydride/anhydroglucose unit (AGU) molar ratio on the DS of starch acetates were investigated.These starch acetates exhibited different solubility in water
acetone and DMAc
depending on the DS value.Finally
the fibrous membranes composing of continuous and smooth fibers with diameters in a range from several tens to several hundreds nanometers were successfully produced via electrospinning of starch acetate solution.
