In this research, the spider silk from the major ampullate gland of native Nephila pilipes was collected via the forced-silking apparatus at the reeling speed of 3 m/min. The obtained silk was dissolved in hexafluoro-isopropanol. The influence of pH and temperature over the secondary structure of the silk protein in solution state was examined via Circular Dichroism. The effect of silk concentration and electrical field strength on the structure conformation of silk protein during film casting process was investigated via FT-IR. During the drying process, the increase of silk concentration and the presence of electric field tend to form β-sheet and β-turn. Finally, the dried film of silk protein was treated with different temperatures and cation solutions to study the post-treatment effects.
