Tribology of Thin PTFE Coatings | Dr. Min | Tribology Webinar

PTFE (Teflon) is famous for its low friction and non-stick properties—but making it durable as a thin coating has challenged engineers for decades. In this TriboNet webinar, Dr. Min, Professor of Mechanical Engineering at the University of Arkansas, shares her research group’s decade-long journey to solve PTFE’s biggest limitation: poor adhesion and weak cohesion. Her team’s bio-inspired approach uses an ultra-thin polydopamine (PDA) adhesive layer, combined with nanoparticles and annealing optimization, to achieve a 500× improvement in coating life—without altering component geometry. Key Topics Covered: Why PTFE is ideal yet problematic for thin coatings Mussel-inspired polydopamine (PDA) as a universal adhesion layer Reinforcing PTFE with gold, copper, and graphite nanoparticles The role of annealing temperature and time in wear resistance Experimental results and molecular simulations of coating morphology Adhesion vs. cohesion: solving one challenge while tackling another Industrial applications in biomedical, aerospace, and precision systems 🔗 Learn more on TriboNet.org: Thin Film Tribology Bio-Inspired Materials in Tribology Nanoparticles in Lubrication and Coatings Coatings and Surface Engineering 👉 Subscribe to TriboNet on YouTube for more expert tribology webinars and research insights. 🔖 Hashtags #Tribology #PTFE #Coatings #SurfaceEngineering #Nanoparticles #BioInspiredMaterials #TriboNet 🏷 YouTube SEO Keywords (Tags) PTFE coating durability polydopamine adhesive layer tribology bio-inspired PTFE coatings nanoparticle-reinforced PTFE ultra-thin PTFE coatings adhesion vs cohesion tribology Dr. Min University of Arkansas PFAS alternatives tribology surface engineering coatings tribology webinar PTFE
