Summary
1. Introduction
The morphological properties have been assessed by scanning electron microscopy (SEM), and the water content material of the collagen movies after the DHT remedy was evaluated by thermogravimetry evaluation (TGA). The impact of DHT remedy, with varied situations on the construction and properties of collagen movies, was investigated on this research to develop satisfying collagen casings. The character of crosslinking and the variation of crosslinking density have been analyzed by evaluating the swelling ratios of collagen movies in deionized water and in aq. urea.

3. Outcomes and Dialogue
4. Conclusions
A constantly rising DHT temperature or time led to critical denaturation and the lower of mechanical properties with a decrease tensile power, the next tensile modulus, and a shorter elongation at a DHT temperature of 145 °C for 1 day or for an extended DHT time over 5 days at 105 °C. The collagen movies present favorable mechanical properties with DHT remedy at 125 °C for 1 day or 105 °C for 3 days. Nonetheless, the lack of a local triple helix construction and the harm of the self-assembly of collagen molecules additionally occurred from the information of IR and SAXS, which decreased the mechanical properties.
