Preparation, physicochemical characterization, and ammonia-responsive behavior of poly(lactic acid) / polypyrrole / oxidized multi-walled carbon nanotube composite films with synergistically enhanced electrical conductivity
This study reports the development of high-conductivity composites based on a biodegradable polylactide (PLA) matrix reinforced with polypyrrole (PPy) and oxidized multiwall carbon nanotubes (OMCNTs). Quantum-chemical modeling using density functional theory (DFT; B3LYP/MidiX, n = 100) established the electronic baseli...
