Paper Title:
Study on Synthesis and Surface Activities of Silk Peptide-Based Surfactants
  Abstract

Silk peptide-based surfactants were synthesized from fatty acyl chloride and silk peptide using Schotten-Baumana method. The structure of the product was characterized by IR and amino acid analysis, and the surface activity of the product was tested. The IR spectra showed the characteristic bands corresponding to the stretching vibration of C=O, N-H, C-N and -COONa groups. The amino acid analysis indicated that there were many kinds of amino acid in the products, and the most ones were glycine and alanine, which made up nearly 95% of the total content of amino acid. The surface activity experiment results showed these surfactants had excellent surface activity. In the homologous compounds of surfactants, the critical micelle concentration (cmc) reduced and the trend of micelles formation increased with the hydrocarbon chain length increasing.
