Insight into the well-balanced mechanical-electrical properties of copper composites is requisite to provide an understanding for development novel structure-function integrated materials. In this study, multi-dimensional hybrid reinforcements, carbon nanotube and zero-dimensional carbonized polymer dots (abbreviated as: CNT+CPD), were incorporated within matrix via spraying pyrolysis dispersion segmented ball milling routes. A strategy was developed simultaneously introduce intragranular CPD intergranular CNT by controlling spatial configuration. Characterization results show that dispersibility interface wettability CNT-Cu improved pyrolysis. Intragranular facilitated trapping accumulation dislocations inside grain interior, which enhanced strain hardening capability. 3.0 vol% CNT-CPD/Cu achieved good strength-plasticity compatibility (410 MPa 19.8%, i.e., 146.6% 139.3% CNT/Cu composites, respectively). Meanwhile, had also displayed electrical conductivity (96.5%IACS), attributed creation conductive graphitic channels locally around produced a potent electric field with little charge loss. This work presented effective route design advanced demonstrated potential in applications as progressive multi-functional
