Integrating Frontier Scientific Research into Experimental Teaching of Environmental Protection in Chemical Engineering:Surface Oleophobic Modification to Enhance PTFE Membrane's Anti-fouling Performance
This undergraduate experiment involves the design of an oleophobic PTFE membrane preparation to enhance its anti-pollution performance in oil-water separation and bacterial solutions.Initially,the plasma grafting method is employed to regulate the lipophobicity of the polytetrafluoroethylene(PTFE)membrane.The experiment includes characterizing the membrane's adhesive force to water and oil contact angle on the membrane surface.Subsequently,the separation performance of the membrane is investigated for oil-water emulsions.Finally,the membrane surface contamination is evaluated using metallographic microscopy.This experiment introduces a novel approach of membrane modification and separation technology for wastewater treatment.Through hands-on experiments,students gain an in-depth understanding of the significant applications of oleophobic membranes in environmental governance and recognize their potential value in the field of chemical engineering.Moreover,it offers students insights into cutting-edge environmental remediation technologies,stimulating their imagination and creativity.
