In order Carbon nanotubes to achieve this objective, poly(D-lactide)/poly(hydroxyalkanoate) (PDLA/PHA) nanocomposites with multi- Conductivity walled carbon nanotubes (MWCNTs) and MWCNTs-g-PLLA (prepared via ring opening polymerization of L- Stereocomplexation lactide with grafting degree of 17%) were designed and fabricated. The grafting of PLLA facilitates the selective Crystallization distribution of MWCNTs in the sole PDLA phase via interfacial stereocomplexation, which in combination with (ϕ = 0.32 wt%) compared to that of the un- the volume exclusion eﬀect of PHA leads to a lower value of
