The morphology of semicrystalline plastics on the 1-100 μm scale, such as spherulites, strongly affect mechanical and other properties of the material but currently only 2D imaging techniques are available. Here, the authors use fluorescence labels and confocal microscopy to visualize the internal structure of neat polymers and composites in 3D and reveal unsuspected morphologies.
