Figure Lengend Snippet: Optical microscopy (10× magnification) images (left) and SEM (5000× magnification) micrographs (right) of Ch (1.0 w/v %) films containing (a) 4-AAB (1.0 wt %), (b) PTPh (2.5 wt %), and (c) PTPh (2.5 wt %)/4-AAB (1.0 wt %). For the samples containing PTPh, the images from optical microscopy were obtained using a Zeiss DAPI filter (λ ex = 365 nm), and the same microscope settings were used for all images to enable the comparison of intensities for the different films. The bars shown in the images of the left and right panels correspond to 20 and 5 μm, respectively.
