Fabrication of complex 3D objects using folding of thin films is a novel and very attractive research field. This manuscript overviews recent progress in development, investigation, and application of self-folding polymer films which are able to fold and form various 3D structures. The review discusses the basic principles of design of self-folding films, fabrication of self-folding films, possibilities to build complex 3D shapes, their responsive properties, and applications.
