Morphology of CAP-HPC composite film H and of particles after film dispersion in water. a, Scanning electron microscopy of film H (side "A" exposed to air during drying). b, 3-dimensional (3-D) interactive display of side "A" of film H. c, 3-D interactive display of film H (side "B" in contact with the casting surface during drying). b, c, Color bar corresponds to elevation scale. d, Kinetics of conversion of shredded film H into a gel as measured by increase of viscosity. e, Scanning electron microscopy of CAP particles from the gel. f, Size distribution of the particles. Scale bar for a and e is 1 µ.
