摘要

This study investigates the physicochemical properties and surface coating performance of PPTA fibers subjected to synergistic acetone and ethanol surface treatments for functional modification. The XRD, Raman, FTIR, and SEM characterizations are employed to unveil the impact on the treatment on the properties. The surface properties of the treated samples exhibit significant enhancements compared to their pristine counterparts. The XRD results demonstrate that the applied treatment does not adversely affect the crystal quality of the PPTA fabrics. Raman and FTIR analyses indicate no structural deterioration and that defects in the C = O groups are eliminated by the treatment. SEM observations reveal that the treatment induces surface reorganization both between fibers and on individual fiber surfaces. Furthermore, the ZnO coating applied to the PPTA surface via the hydrothermal method produces a more homogeneous and denser layer by reducing surface defects after treatment. The modified PPTA fiber surfaces therefore offer promising potential for the fabrication of high-performance devices based on these materials.
