Shish-kebab Structure


Shish-kebab structure is the polycrystalline morphology of double habit consisting of fibrous crystals overgrown epitaxially by lamellar crystals, the stems of which are parallel to the fibrous axis where fibrous crystals are type of crystals significantly longer in one dimension than in either of the other two and lamellar crystals are type of crystals with a large extension in two dimensions and a uniform thickness.


Fibrous and lamellar parts (equivalent to shish and kebab respectively) of a shish-kebab structure can have similar or different constituents, for example they both can be made of similar polyethylene (PE) chains or it is possible to have a carbon nanotube as the shish and agglomerations of polyethylene chains as kebabs.
