Soft Materials


Course Description

Introduction to soft condensed matter, including the general aspects of chemistry, physical properties, structure and dynamics, and applications of soft materials (including polymers, colloids, liquid crystals, amphiphiles, gels, and biomaterials). Emphasis is placed on the molecular forces related to self-assembly.

Additional Requirements for Graduate Students:
Graduate students will be required to complete bi-weekly literature summaries and develop a research design project based on a related subject. The graduate students give a presentation based on their project to the rest of the class.

Course Objectives

This course will serve as an introduction to soft condensed matter for students with a background in biological engineering, chemistry, physics, and materials science. It covers general aspects of chemistry, physical properties, structure and dynamics, and applications of soft materials (including polymers, colloids, liquid crystals, amphiphiles, gels and biomaterials). Emphasis is placed on the molecular forces related to self-assembly. Topical coverage includes: (a) forces, energies, and kinetics in material synthesis, growth and transformation; (b) synthetic methods for preparing materials; (c) formation, assembly, phase behavior, and molecular ordering of synthetic soft materials; (d) structure, function, and phase transition of natural materials (nucleic acids, proteins, polysaccharides and lipids); (e) techniques to characterize structure, phase and dynamics of soft materials (f) application of soft materials in nanotechnology. Recent examples from the literature will be used to illustrate technologically relevant materials in current nanoscience, nanotechnology, and nano-biotechnology, such as block copolymers thin films, colloidal photonic crystals, micelles, vesicles, hydro-gels, photosensitive materials, and materials in soft lithography.
