Thin, Lightweight, and Highly Efficient Electromagnetic Interference Shielding Nanocomposites Composed of a π-Conjugated Block Copolymer Nanowire/Multiwalled Carbon Nanotube Bicontinuous Interpenetrating Network.

ABSTRACT: We developed high-performance electromagnetic interference (EMI) shielding composites by integrating a π-conjugated block polymer system with carbon nanofillers. First, a poly(3-hexylthiophene)-poly(ε-caprolactone) (P3HT-PCL) block copolymer system was synthesized through a combination of Grignard metathesis, tail modifications, and ring-opening polymerization. Controlling the solvent type and aging time resulted in the self-assembly of the P3HT-PCL chains into nanoscale fibers. When multiwalled carbon nanotubes (MWCNTs) were added to the P3HT-PCL solution, the π-π interactions between the thiophene rings of P3HT-PCL and the benzene units of the MWCNTs facilitated the dispersal of MWCNTs in the hybrid solution. Self-assembled P3HT-PCL chains prompted the formation of a nanofibrillar framew
