NANOSTRUCTURE CHARACTERIZATION OF BETA-SHEET CRYSTALS IN SILK UNDER VARIOUS TEMPERATURES

ABSTRACT
This paper studies the nanostructure characterizations of β-sheet in silk fiber with different reaction temperatures. A molecular dynamic model is developed and simulated by Gromacs software packages. The results reveal the change rules of the number of hydrogen bonds in β-sheet under different temperatures. The best reaction temperature for the β-sheet crystals is also found. This work provides theoretical basis for the designing of materials based on silk.
