For the first time, biocompatible and biodegradable Ta-metal organic framework (MOF)/polyether block amide (PEBA) fibrous polymeric nanostructures were synthesized by ultrasonic and electrospinning routes in this study. The XRD peaks of products were wider, which is due to the significant effect of the ultrasonic and electrospinning methods on the final product. The adsorption/desorption behavior of the nanostructures is similar to that of the third type of isotherm series, which showed mesoporous behavior for the products. The sample has uniform morphology without any evidence of agglomeration. Since the adsorption and trapping of gaseous pollutants are very important, the application of the final Ta-MOF/PEBA fibrous polymeric nanostructures was investigated for CH adsorption. In order to achieve the optimal conditions of experiments and also systematic studies of the parameters, fractional factorial design was used. The results showed that by selecting temperature 40°C, time duration 35 min, and pressure 3 bar, the CH gas adsorption rate was near 4 mmol/g. Ultrasonic and electrospinning routes as well as immobilization of Ta-MOF in the PEBA fibrous network affect the performance of the final products for CH gas adsorption.
在本研究中，首次通过超声和静电纺丝路线合成了具有生物相容性和可生物降解性的钽基金属有机框架（MOF）/聚醚嵌段酰胺（PEBA）纤维状聚合物纳米结构。产物的XRD峰较宽，这是由于超声和静电纺丝方法对最终产物有显著影响。纳米结构的吸附/解吸行为类似于第三类等温线系列，表明产物具有介孔行为。样品具有均匀的形态，没有任何团聚迹象。由于气态污染物的吸附和捕集非常重要，因此研究了最终的Ta-MOF/PEBA纤维状聚合物纳米结构对CH吸附的应用。为了实现实验的最佳条件并对参数进行系统研究，采用了分数析因设计。结果表明，选择温度40°C、持续时间35分钟和压力3巴时，CH气体吸附率接近4 mmol/g。超声和静电纺丝路线以及Ta-MOF在PEBA纤维网络中的固定化会影响最终产物对CH气体吸附的性能。
