“…The model predicts peaks at 0 and AE438 in the azimuthal intensity scan of the g-form (117) reflection. [27] Our experimental results are in good agreement with theoretical calculations of the model.…”

“…[20] Interestingly, the (117) reflection of g-form displays a similar azimuthal scan to that of the a-form (130) reflection, and is thus consistent with the well-known a-g epitaxial model in iPP. [27] In this model, g-form iPP branches from both mother and daughter lamellae of a-form iPP with an epitaxial angle of %408. The model predicts peaks at 0 and AE438 in the azimuthal intensity scan of the g-form (117) reflection.…”

CNT‐induced formation of transcrystals of γ‐PP are reported. Formation of these transcrystals occurred when PP was infiltrated into nanotube aerogel fibers to form polymer nanocomposites. The PP morphology and microstructure with particular focus on the interfacial region of the CNTs were investigated by means of SEM, DSC and WAXD. The transcrystalline supramolecular microstructures were observed around the individual nanotubes during quiescent melting crystallization. Microstructural analysis showed that γ‐form transcrystals of PP dominate the overall interfacial structure. The content of γ‐form transcrystals increased with increase in nanotube loading. The mechanical properties and electrical conductivities of the nanocomposites have been evaluated.magnified image

“…as g-form crystals are generally observed under high pressure crystallization [32] or under shear-controlled-orientation, for example during injection moulding [33]. Because a-form crystals grow much faster than g-ones [34,35], the former crystals predominate the overall transcrystalline interphase.…”

“…[33,34] To our knowledge, however, this is the first example of a polymer that yields an oriented c-form by cold stretching in which the a phase is almost completely absent. This is, of course, related to the very poor stereoregularity of these samples.…”
