摘要：Porous zirconia ceramics possess a unique combination of low density, exceptional corrosion resistance, outstanding high-temperature stability, and inherent chemical inertness, which collectively underpin their growing utility in biomedical engineering, advanced filtration and separation systems, and high-temperature insulation applications. In this work, porous zirconia ceramics were prepared using an in-situ polymer blowing strategy. During foam formation and growth, the ceramic skeleton was concurrently constructed and densified, while ceramic particles were robustly anchored and homogeneously distributed throughout the template network resulting in a marked reduction in structural defects. A synergistic interfacial engineering strategy combining continuous liquid-phase modulation with targeted surface functionalization of nanoparticles was employed to robustly enhance structural integrity. Specifically, N,N-dimethylformamide (DMF) was introduced to tailor the rheological behavior of the suspension and ensure homogeneous gelation, whereas propyl gallate was strategically utilized to confer hydrophobic surface functionality onto zirconia nanoparticles thereby strengthening interfacial adsorption and enhancing skeletal structural stability. This approach simultaneously optimized the microstructural architecture and synergistically enhanced the mechanical robustness and acoustic attenuation of the porous zirconia ceramics. As a result, the optimized porous zirconia ceramics attained a compressive strength of 0.272 MPa at a porosity level as high as 94.17%. Furthermore, these materials demonstrated exceptional acoustic performances: an average sound absorption coefficient of 0.451 across the 1200-3600 Hz frequency band and a pronounced peak of 0.836 at 2800 Hz. These findings demonstrate that the developed ceramics are uniquely suited for noise reduction in high-temperature and other harsh environments, thereby establishing a scalable rational pathway toward the industrial fabrication and multifunctional deployment of high-performance porous ceramics.
