Embodiment Construction

[0018] First, the preparation of paraffin / polyimide composite film

[0019] Fix the polyimide film on a glass plate with a flat surface, heat to 250°C and keep it for 2 hours, then cool to room temperature to keep the polyimide film isotropic. Then sprinkle the paraffin wax powder on the surface of the polyimide film, heat it to 60-100°C, and transfer it to a spin coater for spin coating while it is hot. When the spin coating speed is controlled at 300-3000 rpm, the density of the paraffin layer can be Controlled at 0.3-1.5mg / cm 2 , after cooling to room temperature, a paraffin / polyimide film was prepared.

[0020] Second, the preparation of aligned carbon nanotubes / paraffin / polyimide films

[0021] The aligned carbon nanotube film is pulled out from the aligned carbon nanotube array, and spread on the surface layer of the paraffin / polyimide film with a thickness of 100-400nm. Then heat it to 60-100°C to melt the paraffin, and evenly enter the gap between the aligned carbon...

Abstract

The invention belongs to the technical field of sensitive materials, and particularly discloses a light-drive deformation-controllable composite and a preparation method thereof. According to the composition and structure of the composite, a polyimide film serves as the substrate, an anisotropy composite layer composed of orientation carbon nanotubes and paraffine serves as the upper layer, and the substrate and the composite layer make close contact. By means of the composite, the response of light drive and thermal drive can be achieved. By controlling the orientation direction of the orientation carbon nanotubes, various deformation forms of facing towards light, backing from light, three-dimensional deformation and the like can be achieved, the content of carbon nanotubes and paraffine is further optimized, and rapid and large-magnitude deformation can be achieved. By means of the light-drive deformation material, a new concept is provided for other intelligent response materials.

Description

technical field [0001] The invention belongs to the technical field of sensitive materials, and in particular relates to a light-driven controllable deformation composite material and a preparation method thereof. Background technique [0002] Intelligent sensitive materials have developed vigorously in recent years. By sensing factors such as light, electricity, heat and humidity in the environment, intelligent behaviors such as shape changes or color changes are produced. This type of intelligent sensitive materials is also the mainstream of future functional material development. direction. Among them, smart materials that generate mechanical motion in response to light have the advantages of remote control and easy manipulation, and are one of the important materials. In recent years, a series of materials with photodeformability, such as azobenzene, have been developed. However, the response deformation of these materials is often slow, the deformation form is single,...
