Applying the concept of microfibrillar composites, microfibrils of poly(butylene terephthalate) (PBT) loaded with 5 wt% multi‐walled carbon nanotubes are prepared by extraction of polypropylene (PP) from drawn PP/PBT blends and shaped into single polymer composites (SPCs). SPCs show superior mechanical performance with up to 300–600% improvement in modulus and tensile strength as compared to neat isotropic PBT. In addition, the microfibrillar SPCs (MF‐SPCs), as well as the single microfibrils, have electrical volume conductivity of 8 × 10 −3 S cm − 1 demonstrating electrical conductive behavior.
