Silk fibroin/clay nanocomposites with ph-controled conformation and clay dispersion
(0) INTRODUCTION The combination of natural proteins and inorganic solids has become an emerging group of hybrid materials, namely bio-nanocomposites 1. Silk fibroin has generated significant interest because of its remarkable mechanical properties, which has been widely used in biotechnological and biomedical areas 2. To expand its application, it is necessary to dissolve silk fiber and regenerate it. Clay has been successfully used as a nanoscale reinforcing phase for a wide range of commodity and natural polymers 3. Proteins are natural copolymers containing both hydrophobic and hydrophilic domains which could interact with clay surface. Therefore, proteins could be used as excellent dispersants to clay. It is envisioned that incorporating clay platelets into silk fibroin would impart high tensile modulus and strength to the nanocomposites. This may open the gateway to producing multifunctional silk materials that may be used as tissue scaffold, artificial tissue, and biodegradable structural materials.
