Nanoscale mapping of semi-crystalline polypropylene

We reveal nanoscale information of semi-crystalline polypropyl-ene with the use of a new secondary electron hyperspectral imag-ing technique. The innovative combination of cryo-SEM and low voltage allows for the optimised imaging of these beam-sensitive materials. Through the collection of secondary electron hyper-spectral imaging data mapping of molecular order on the nano-scale in the scanning electron microscope (SEM) can be achieved.
