The invention relates to a method for preparing a stretchable film-like structure, comprising: providing an elastic base, pre-stretching the elastic base along a first direction and a second direction, so that the elastic base is in a stretched state, and the first direction perpendicular to the second direction; the carbon nanotube film-like structure is laid on the surface of the elastic substrate in a stretched state, the carbon nanotube film-like structure includes a plurality of stacked super-parallel carbon nanotube films, each super The parallel carbon nanotube film comprises a plurality of carbon nanotubes, and the plurality of carbon nanotubes extend substantially in the same direction; A plurality of folds are formed on the surface of the carbon nanotube film-like structure, and the folds enable the stretchable film-like structure to be stretched in multiple directions simultaneously when being stretched in multiple directions. The present invention also provides a stretchable film-like structure obtained by the above method.
Description
technical field [0001] The invention relates to a stretchable film-like structure and a preparation method thereof, in particular to a stretchable film-like structure that can be stretched in different directions with a large strain. Background technique [0002] Stretchable film-like structures can be applied in many fields, such as stretchable energy storage devices, flexible touch screens, etc. The carbon nanotube film-like structure has certain flexibility and is a commonly used stretchable film-like structure. However, the existing carbon nanotube film-like structure can only be stretched in a single direction with a small strain, and it is easy to break when it is stretched repeatedly with a large strain in different directions at the same time. Therefore, it is very meaningful to provide a stretchable film-like structure that can withstand repeated stretching under high stress in different directions and a preparation method thereof.
