Characterisation of Collagen from the Skin of Catfish ( Pangasius sp) for Innovative PVA-Collagen Nanofiber

摘要

Preparation of PVA-Collagen nanofiber plaster production begin by repairing the skin of catfish, then collagen is extracted with distilled water. Extracted collagen need to be frozen dry so that collagen can be obtained in the form of sheets, powder, or crystals. The next step is the production of PVA-Collagen nanofiber, a 10% solution of polyvinyl alcohol (PVA) is mixed with a previously prepared extracted collagen and stirred until it forms a homogeneous mixture. Next, PVA-Collagen nanofiber is formed by the electrospinning method. The results of characterization using FTIR found three main groups in six variations: amide group A; amide I; and amide II. Amide A has a wave number in the range 3300-3440 cm-1, amide I is in the range 1625-1690 cm-1, and amide II is in the range of 1480-1575 cm-1. Characterization was carried out to determine the surface morphology of the observation in the sample using Photomicrograph (200 μm) with magnification 10x, produced fiber diameter formed in variations of PVA-Collagen 1% 116-120 μm while in the variation of PVA-Collagen 1% + Chitosan 10 drops in diameter 41-50 μm.
