In this article, the high-performance polymer composites were prepared based on the morphology designing method. To begin with, the beta transcrystalline morphology in the interfacial region of isotactic polypropylene (iPP) composites supported by single carbon fiber was formed by the induction of beta nucleating agent (NA) and verified using the polarized light microscopy. Then, to further explore the application of the beta transcrystalline morphology, the way of induction by supported NA was introduced into the iPP injection-molded samples. The result showed that a certain number of interfacial beta transcrystallinity was formed in the adjacent region of carbon nanotubes–modified iPP injection-molded samples. Herein, the mechanical properties are closely related to the interfacial beta transcrystalline morphology, the convective evidence was the improvement of the sample’s impact strength by seven times. Therefore, this work gives a new perspective for the preparation of high-performance composites materials via morphology designing.
