“…Although the transcrystalline kinetics, microscopic details of transcrystallization and their processing condition dependence were well documented, little information about the effect of transcrystalline interphase on the macroscopic performance and the mechanism involved in the semicrystalline polymer-based composite was availed. Some studies found that transcrystallization improved interfacial bonding [16] as well as transverse strength of unidirectional composite [17], while Ogata and co-workers [18] proved that the bonding strength was not directly influenced by the formation of transcrystalline layer. The effects of transcrystallization on the interface and properties of composites remain in dispute.…”

For polymer composites, interfacial crystalline structures retain an important role in the macroscopic properties and are significantly affected by the processing conditions, such as the temperature, time, and external field. In this study, the transcrystallization behavior of the carbon nanotube fiber and isotactic polypropylene composite was investigated by polarizing light microscopy. The influence of the formation of the transcrystalline layer on the interfacial adhesion was evaluated by a single-fiber fragmentation test. The results show that the growth rate of the transcrystalline layer was strongly influenced by the isothermal crystallization temperature, and the interfacial shear strength was markedly enhanced by the formation of the layer. The interfacial adhesion was further increased with the gradual perfection and growth of transcrystallinity.

“…XRD results confirmed that with typical industrial scale parameters, there is a lack of compatibility and interaction between the matrix and the surface of the CF-Z fibres since crystallinity improvement trough transcrystallinity is not detected. Indeed, as far authors know, transcrystallinity has only been observed by microscopy with very slow cooling parameters [41] with pitch-based carbon fibre-reinforced PEEK composites.…”

This work addresses the challenging fibre-matrix compatibilization and interface adhesion improvement of poly(etheretherketone) (PEEK) composites reinforced with pitch-based carbon fibre. An innovative and environmentally friendly method, inspired both by supramolecular "layer-by-layer" (LBL) assembly and by the composition of adhesive proteins in mussels was designed to modify the carbon fibre surface and improve the composites transverse properties by supramolecular interactions. The results proved that few sensitive carbon surfaces can be selectively modified by stable polyelectrolyte complexes and catechol amine polymer partners dispersed in water in such a way that a sizing treatment can be applied by techniques as simple as immersion or spraying procedure. It was shown that the combination of these solutions self-organized to form thin deposits containing compatibilization and/or crystallization promoter partners, thought transcrystallinity, onto carbon surface. This approach is an innovative and environmentally-friendly method which improves fibre-matrix interface quality in terms of compatibilization, adhesion and mechanical properties.
