文摘
- •
An approach to engineer bi-continuous conductive polymer blends was developed.
- •
Compatibilization in a phase separating blend resulted in double percolation of MWNTs.
- •
Double percolation provided a huge conductivity increase at low MWNT concentration.
- •
Compatibilization was achieved by readily available and inexpensive long random copolymer.
- •
Interfacially segregated copolymer resulted in morphology refinement and increased phase continuity.
