Polylactic acid with zirconium oxide solution has been deposited by air-jet spinning to obtain a PLA/ZrO₂ composite. Zirconium oxide is obtained by hydrothermal technique and the results indicate that zirconia is nanostructured, mesoporous and thermally stable. The precursor solutions are formed by different amounts of PLA and zirconia. PLA/ZrO₂ composite is formed by nanofibres with a random distribution, non-porous and with diameter of fibres depending of PLA and zirconia concentrations. It is found that the incorporation of zirconia makes the PLA fibres harder, less flexible and mesoporous. However, the thermal properties are not affected by the zirconia incorporation. The findings show that PLA/ZrO₂ composite can be utilized as biomaterial.

喷气纺合成PLA纳米纤维和PLA / ZrO2介孔复合材料的理化特性

通过喷气纺丝沉积具有氧化锆溶液的聚乳酸以获得PLA / ZrO ₂复合材料。通过水热技术获得了氧化锆，结果表明氧化锆是纳米结构的，介孔的和热稳定的。前体溶液由不同量的PLA和氧化锆形成。PLA / ZrO ₂复合材料由具有随机分布，无孔且纤维直径取决于PLA和氧化锆浓度的纳米纤维形成。发现掺入氧化锆使PLA纤维更硬，更不柔软和中孔。但是，热性能不受氧化锆掺入的影响。研究结果表明，PLA / ZrO ₂复合材料可以用作生物材料。
