Polyfunctional Materials Based on Collagen Hydrolysate Obtained from Swim Bladders of Northern Fish Species

Abstract

In recent years biopolymer fillers are widely used to development of composite materials for various purposes. In this respect collagen hydrolysate (HC) is one of the most promising biopolymer for modification of synthetic polymers to produce different types of item. In this work, a new source of collagen has been tested - collagen hydrolysate obtained from a swim bladder of northern fishes. The cure characteristics, mechanical and relaxation properties, abrasion resistance of the Butadiene–acrylonitrile rubber composites containing the collagen hydrolysate have been discussed. The chemical compositions, properties, morphology of collagen hydrolysates have been studied. It was shown by means of IR spectroscopy that the bands of Amide I, Amide II, Amide III, Amide A, which is related to the vibrations of the polypeptide bond of the protein, are recorded in the infrared spectra of the samples. The morphological structure of collagen was investigated by scanning electron microscope JSM-7800F ("JEOL", Japan). The size and the zeta potential of collagen hydrolysate were investigated by Dynamic Light Scattering (DLS) on the Zetasizer nanoZS instruments (Malvern Instruments Ltd., UK).

“…Other authors reported a polydisperse solution of hydrolysed collagen, with diverse particle size from 65 nm to 246 nm [ 45 ], or from a low value up to around 5000 nm [ 46 ]. The largest particle (~5500 nm), which is monodispersed and different from the other three smaller groups with broader distribution, could be due to the insufficient concentration of alkali used during the synthesis process of collagen [ 46 ].…”
