Large-scale preparation of segregated PLA/carbon nanotube composite with high efficient electromagnetic interference shielding and favourable mechanical properties

Segregated structure poly (lactic acid) (PLA) conductive composites with efficient electromagnetic interference (EMI) shielding performance and favourable mechanical properties were easily fabricated by injection molding from poly (l-lactid acid) (PLLA), poly (lactic acid) stereocomplex crystallite (PLASC) and multi-wall carbon nanotube (MWCNT). Due to the selective dispersion of conductive MWCNT filler in the continuous PLA phase, good conductivity and high EMI shielding effectiveness (EMI SE) were achieved under low MWCNT content.240
