Natural biomaterials were used to improve the biocompatibility of synthetic biopolymers. PCL was electrospun with natural biopolymers, silk fibroin, and small intestine submucosa. Due to increased electrical conductivity, the diameter of the composite fibers highly depended on the amount of SIS in the polymer solution. PCL/SF/SIS electrospun composites exhibited various synergistic effects, including enhanced mechanical properties and incredibly improved hydrophilicity compared to those of pure PCL and PCL/SF fibers. An initial cell attachment test demonstrated that the interactions between PC‐12 nerve cells and the PCL/SF/SIS composites were more favorable than those between PC‐12 cells and a PCL/SF composite.
