Schematic representations showing the transfer and localization of MWCNTs in PLLA/elastomer blends with a sea-island phase structure during melt-mixing process: (a) MWCNTs are pre-dispersed in poor wetting PLLA matrix and subsequently melt-mixed with a more favorable EGD elastomer phase; (b1-b2) generally, MWCNTs prefer to transfer from PLLA matrix to dispersed elastomer particles; (c1-c2) if SC crystallites could be rapidly formed at the interface of PLLA/EGD blend, some MWCNTs would be anchored by the interface-localized SC crystallites when they transfer across the interface (adapted from reference [145]).
