It has been shown that the stiff ordering polymer layer, which coats CNTs and arises from a heterogeneous nucleation effect, could play a positive role. In the study, interfacial enhancement is realized through conventional processing, such as injection molding or melt-spinning, which offers the potential for practical application.

The group, which is based in the college of Polymer Science and Engineering at Sichuan University, reports the results of a non-covalent interaction induced by a strain field, which gives a dramatic improvement in mechanical strength.

The study suggests a new, promising pathway to attaining CNT composites with ultrahigh mechanical properties via a simple and highly efficient melt-spinning process.
