and a 340% increase in char yield, while the Limiting Oxygen Index (LOI) increased from 19.1% (neat PLA) to 27.5% after nine cycles. Surface engineering steps-including NaOH etching and PEI functionalization-enhanced wettability and facilitated uniform GNP deposition, improving strong adhesion, especially at lower coating cycles.
