The development of polymer nanocomposites is a significant technological advancement in academia and industry, and the morphological control of matrix materials is important in processing these polymer composites. Ming Wang et al. successfully fabricate transcrystals in isotactic polypropylene (iPP)/CaCO 3 nanocomposites by controlling the stratified distribution of CaCO 3 . The β‐form crystals prefer to form in the stratified samples with thick transcrystals, which can be tuned by the content of CaCO 3 and the cooling rate of the processing. The transcrystals, which fill the most area of the neat iPP layers, can improve the mechanical properties of the iPP/CaCO 3 nanocomposites. The cover shows a micrograph of the transcrystallization at the interfaces of the iPP layers and iPP‐20 layers. DOI: 10.1002/app.39632
