Web16 Jan 2024 · A shish-kebab polymer crystal usually consists of a central fibril ( shish) and disk-shaped folded-chain lamellae ( kebab) oriented perpendicularly to the shish as … Webthe shish-kebab structure is a long and macroscopically smooth extended-chain crystalline assembly, which orig-inates from the oriented and/or extended chains under flow. The shish provides nucleating sites (or primary nuclei) for lateral growth of folded-chain crystals or kebabs. In the 1970s, a great deal of effort was devoted to elucidate the

WebThe crystal structure in CNT/polymer composites has a “shish-kebab” geometry [42,43,44]. Indeed, the local temperature in the region of crystal birth can be significantly increased due to the heat released at crystallization even under isothermal boundary conditions for … WebAbove a certain threshold, the number of shish-kebabs formed affects the rheology such that further structure formation is halted. The critical amount is reached already within 0.1 s under the current flow conditions. The change in rheology is hypothesized to be a consequence of the “hairy” nature of shish.
