Effect of anionic surfactants on grafting density of gelatin modified with PDMS-E

- Ordered arrangement of gelatin chains at a fluid interface observed by HR-TEM.
- Anionic surfactants played a key role in causing interfacial compatibility.
- The reduction of interfacial free energy calculated by ΔGM.
- The energy controlled by hydrophobicity-driven interaction in the mixed system.
- MD simulations conclusions confirmed the experiment result.
