Inside Cover, Volume 133, Issue 26

Shengnan Zhang, Hai Wang, Duigong Xu, Wenxiao Yang, Ping Tang and Yuezhen Bin examine the crystallization behavior of poly(vinylidene fluoride) (PVDF) and transcrystallization in carbon fiber/PVDF composites under temperature gradients. The cover image, taken using polarized‐light optical microscopy, exhibits a unique doubled transcrystalline layer with PVDF α and γ phases at the interface of the PVDF/ carbon fiber composites. On the carbon fiber, transcrytallization of PVDF γ phase (orange) occurs, which induces the growth of the transcrystalline α phase (yellow). (DOI: 10.1002/app.43605 )
