This invention discloses a method for preparing a PEI-anchored KNN / PVDF-TrFE piezoelectric membrane, belonging to the field of water treatment membrane materials and membrane fouling control technology. Addressing the challenges of existing piezoelectric membranes in achieving both high permeability and effective piezoelectric response, as well as the severe membrane fouling in membrane bioreactors and the high energy consumption and potential damage to membrane materials associated with traditional fouling control methods, this invention uses P(VDF-TrFE) as the membrane matrix, lead-free piezoelectric ceramic potassium sodium niobate (KNN) as the functional filler, and polyethyleneimine (PEI) as the interface anchoring agent. A solvent-free / temperature-induced phase separation method is employed to prepare the composite piezoelectric membrane. After optimization using response surface methodology, the resulting membrane achieves a pure water flux of 2180 L / m² / h and a piezoelectric coefficient d₃₃ of 30.2 pC / N under optimal conditions. Driven by a 10 V, 50 Hz AC electric field, the composite membrane exhibits a localized inverse piezoelectric response at the pore edges, reducing the fouling layer thickness by approximately 30% and increasing the steady-state flux by approximately 184%, demonstrating excellent in-situ antifouling performance. This method has a simple preparation process and uses environmentally friendly materials, which can provide a functional membrane material basis for MBR membrane fouling control in municipal and industrial wastewater.

This invention discloses a method and apparatus for solute removal in hemodialysis with precise membrane pore size control, belonging to the field of blood purification technology. The method involves introducing blood and dialysate into both sides of a dynamically controlled bilayer heterostructure dialysis membrane, collecting characteristic signals of metabolic solutes and plasma functional proteins in the blood, inputting these signals into an adaptive pore size decision model, and outputting target pore size and electric field strength parameters. A low-frequency alternating electric field drives reversible conformational changes in stimulus-responsive polymer chains within the membrane, achieving precise control of the membrane channel's effective sieving pore size, locking the pore size within a threshold range where small molecule solutes permeate while plasma functional proteins are completely retained. Combining axial gradient channels and radial charge sieving mechanisms within the membrane achieves graded and targeted solute removal. A piezoelectrically driven periodic micro-pulsating flow field removes the fouling layer from the membrane surface, improving mass transfer stability. This invention automates and precisely controls the dialysis process, improving solute removal efficiency and plasma protein protection.
