Field emission scanning electron microscopic images for the nanoparticle-incorporated polymer composite on self-integrated scaffold films with and without cross-linking (blank).
Notes: Left side is a representative magnified field emission scanning electron microscopic image of the right side image of an integrated scaffold film. Blank film shows blended polymer scaffold structure. S1, S2, and S3 have no nanoparticles on the surface of the scaffolds, but all the nanoparticles are incorporated into the films. S3 shows scaffolds, with a uniform network structure and S4 shows a regular nanoparticle incorporation into scaffolds, forming a uniform network structure.
