“…These results suggest that the structural development of the PC/MWCNT and HDPE/MWCNT composites during the annealing procedure is attributed to the rotational diffusion of the MWCNTs in the molten PC and HDPE, owing to Brownian motion. Similar results were reported previously 13,22,28,29) .…”

We investigated changes to the linear viscoelastic properties of a mixture comprising polycarbonate (PC) containing 3 wt.% of a multiwalled carbon nanotube (MWCNT) and high-density polyethylene (HDPE), also containing 3 wt.% MWCNT, during post-processing annealing. The oscillatory shear moduli-i.e., the storage modulus G′ and the loss modulus G′′-gradually increased with residence time in a rheometer (i.e., annealing). The samples were prepared by compression-molding at low temperature, during which the MWCNTs became oriented by the applied squeeze flow. The marked increase in the oscillatory moduli may be attributed to the formation of a conductive MWCNT network owing to Brownian motion. Furthermore, the moduli increased more rapidly during high-temperature annealing. These increases can be expressed by a simple equation using only one characteristic time, i.e., the time required for MWCNT redistribution by Brownian motion. This characteristic time is considered one of the factors that control the structure of composites containing MWCNTs.

“…They found that PBT fibers are transferred from molten PP to PE, which results in the surface-modified PE sheet after separation of the laminated sheets. Similarly, nanofibers of polytetrafluoroethylene (PTFE) in a molten poly(lactic acid) (PLA) are transferred from PLA to PP during the annealing procedure, although PTFE does not transfer from PP to PLA [19]. These results indicate that the localization phenomenon is attributed to the compatibility with nanofillers.…”

“…Doan et al conducted the annealing procedure using laminated sheets composed of pure PE and polypropylene (PP) containing nanofibers of poly(butylene terephthalate) (PBT) [19]. They found that PBT fibers are transferred from molten PP to PE, which results in the surface-modified PE sheet after separation of the laminated sheets.…”

a b s t r a c tA contradict interphase transfer of multi-walled carbon nanotubes (MWCNT) is detected in the immiscible polymer pair of polyethylene (PE) and polycarbonate (PC). When laminated sheets composed of PE with MWCNTs and PC are annealed in the molten state of both polymers, MWCNTs are found to move from PE to PC. This transfer phenomenon is originated from the difference in the interfacial tension with the aid of Brownian motion. On the contrary, MWCNTs prefer to reside in the PE phase in the blend of PE, PC and MWCNTs, even when MWCNTs are first dispersed in PC. This result indicates that MWCNTs transfer from PC to PE. The opposite direction of the transfer is attributed to the PE molecules being adsorbed on the surface of MWCNTs, which are generated during mixing.

“…Структура композиційної мононитки або плівки, що виходить із отвору фільєри, являє собою суцільну фазу дисперсійного середовища, наповненого тонкими струменями (фібрилами). Після екстракції матриці з композитів розчинником, інертним щодо полімеру дисперсної фази, залишаються пучки мікро-і нановолокон або неткані полотна з них [7][8][9][10][11][12].
