Soft Matter Physics

Masao Doi


Soft matter represents a collection of materials such as polymer, colloids, surfactants, and liquid crystals and their composites. These materials do not belong to conventional classes of materials (simple fluids or solids), but they are used extensively in our everyday life and in modern technology (in displays, device manufacturing, energy-saving technology, bio-medical applications, etc.). Soft matter consists of units much larger than atoms; their typical length is 0.01 μm–100 μm. This gives two characteristics to soft matter: large non-linear response to external forces; and long relaxati ... More
