The formation of a network at a high carbon nanofiller content can remarkably improve the thermal conductivity of polymers. The cover by Jing‐Bin Chen et al. shows a micrograph of dense carbon nanotube (CNT) and graphene nanosheet (GNS) networks. Because of the different dimensionalities of carbon nanofillers, the connection types in these two networks differ: CNTs link to each other in a dot‐to‐dot manner, while GNSs exhibit plane‐to‐plane connections. The disparity of microstructures in the networks leads to diverse influences on the crystallization kinetics of iPP. The nanofiller networks show two competitive effects on iPP crystallization: the nucleation effect and the confinement effect. The CNT network has stronger nucleation and confinement effects than the GNS network. DOI: 10.1002/app.39505
