AI Technical Summary
In the existing microbial mineralization preparation technology for ferroelectric Nixing pottery, the microbial metabolic pathway is fixed, the generation efficiency and structural controllability of ferroelectric precursors are poor, and chemical doping and microwave radiation do not form a dynamic synergy, resulting in uneven dispersion of dopants, insufficient ferroelectric phase transformation, and single product function, which makes it difficult to meet the needs of efficient material aging and rapid water molecule cluster transformation.
A composite bacterial agent was formulated using a targeted modified microbial community. Combined with microwave and ultrasonic multi-field coupling technology, a doping system of hydroxyapatite, nano-barium titanate, and poly-N-isopropylacrylamide was introduced. By optimizing the activity of microbial enzymes through gene editing, the targeted synthesis of ferroelectric precursors and the dynamic regulation of dopants were achieved, forming a gradient-distributed ferroelectric structure.
It enhances the spontaneous polarization intensity and temperature response capability of ferroelectric Nixing pottery, promotes the adaptive adjustment of the material aging process, improves the mechanical properties and aging efficiency of the finished product, and solves the problems of brittleness and easy breakage of traditional Nixing pottery.
