Introduction to Instability and Patterning of Thin Polymer Films

Thin polymer films are foundational to modern technology, playing critical roles in coatings, sensors, and microelectronics. Understanding how these films become unstable and form patterns is key to engineering next-generation surfaces. This text-only course provides a clear, step-by-step introduction to the physics, thermodynamics, and fluid mechanics that govern thin film behavior. You will progress from core concepts of surface tension and intermolecular forces to advanced micro- and nano-patterning techniques used in the industry today. What you'll learn: Understand the fundamental thermodynamic principles and intermolecular forces driving thin film instability; Analyze dewetting phenomena and the transition from uniform films to isolated droplets; Learn key patterning techniques including photolithography, soft lithography, and self-assembly; Apply mathematical models of fluid flow at the micro- and nano-scale to predict film behavior; Explore current industry applications of patterned surfaces in biotechnology, optics, and flexible electronics. The course begins with essential terminology, basic surface science concepts, and foundational definitions before moving into practical patterning methodologies and engineering design principles. This course is designed for beginners, students, and researchers in materials science, chemical engineering, or nanotechnology who want a solid foundation in surface patterning without needing prior advanced coursework.
