摘要

This study reports the fabrication of ABS/CuO–MWCNT hybrid nanocomposites via fused deposition modeling (FDM) to enhance mechanical, electrical, and triboelectric performance. Functionalized multi-walled carbon nanotubes (MWCNTs) decorated with copper oxide (CuO) were incorporated into ABS at different loadings (0.25 to 0.75 wt%). XRD confirmed successful hybridization and uniform filler dispersion. Mechanical testing showed maximum tensile and flexural strength at 0.5 wt% due to efficient stress transfer and strong interfacial adhesion. Electrical conductivity and triboelectric output voltage (from 1 to 10 V) improved significantly with filler addition, attributed to enhanced charge mobility and surface roughness. The optimized ABS/0.5-wt% CuO–MWCNT composite demonstrates excellent multifunctional performance, making it a promising candidate for energy harvesting and flexible electronic applications.
