   Recently, the Natural Food Polymer Team of Shaanxi University of Science and Technology published an online publication titled”Tug-of-War-Inspired Bio-ba“”sed Air Filters with Advanced Filtration Performance”. Inspired by tug-of-war repulsion, the author constructed an oriented zein nanofiber ([email protected]) by designing an electrospinning receiving substrate and applied it to ethylene In the field of adsorption and air purification. Compared with similar gas adsorption membranes, [email protected] has good antibacterial, hydrophobic and filtering properties. Shaanxi University of Science and Technology is the first communication unit of the paper, Associate Professor Fan Xin is the first and corresponding author of the paper, and Associate Professor Cao Yungang is the corresponding author of the paper.
  ●Introduction of Achievements
  Zin is a natural plant protein with good hydrophobicity and oxygen barrier properties, which can effectively reduce the impact of water, oxygen and other environmental factors on its product performance. Zein-based nanofibers have become a research hotspot in the field of gas adsorption. In this paper, zein solution is used as the electrospinning solution, and a variety of electrospinning receiving substrates are designed to construct zein-based nanofibers with different orientations. The research is carried out by SEM-EDAX, FTIR, TGA, mercury porosimeter and other methods. Its structural characteristics, antibacterial activity, mechanical properties, gas and particle filtration performance, etc. The results show that the traditional zein-based nanofiber membrane (zMFs-PT) has an average diameter of 1.75 μm, no orientation, a pore area of ​​0.826 m2g-1, and a porosity of 43.02%. The oriented zein-based nanofiber membrane ([email protected]) has an average fiber diameter of 190 nm, an orientation degree of -30°-30°, a pore area of ​​5.154 m2g-1, and a porosity of 47.85%. Based on the above structural characteristics, [email protected] has better antibacterial activity, mechanical properties, hydrophobic properties, gas and particle filtration performance, and provides it for further application in the field of fruit preservation in the field of ethylene adsorption and PM filtration in the environmental field.了基。 The foundation.
