Scan-Gallery: Poly(styrene-block-isoprene) electrospun nanofibers

AFM tomography images of poly(styrene-block-isoprene) electrospun nanofibers enveloped with a silica sheath. The evolution of the block copolymer in the axial direaction domains is clearly observed in the tomography reconstruction. 2.5х2.5х0.5 um, 16 layers.
