Abstract

Gelatin/chitin nanofibers were prepared by electrospinning. Various solutions were obtained by mixing a 27 % (w/v) gelatin in formic acid solution with crab shell chitin dissolved in a mixture of trichloroacetic acid and formic acid in 1:4 volume ratios. Obtaining electrospinnable gelatin/chitin solutions required the decrease of chitin molecular mass. Two types of depolymerisation processes were tested: microwave irradiation and ultrasonic treatment. By variation of irradiation parameters, an optimum was found with the microwave reactor working in temperature control mode. The chemical and physical structure of the gelatin/chitin nanofibers were investigated by scanning electron microscopy and infrared spectroscopy..
