Embodiment 1

[0027] see Figure 1-4 Shown:

[0028] A flexible phase-change artificial muscle material, comprising a flexible silica gel matrix 1, a phase-change liquid 2, a thermal conductivity enhancer, a heating resistance wire 3 and an outer nylon mesh, wherein the flexible silica gel matrix 1 contains nano-dispersed ions, and the The phase change liquid 2 is evenly distributed in the flexible silica gel matrix 1 in the form of vacuoles, and the thermal conductivity enhancing additive is evenly dispersed in the flexible silica gel matrix 1. After the material is manufactured, the nylon braided mesh is wrapped outside, and the resistance wire is energized to generate heat change. As a result, the phase change fluid 2 produces a liquid-vapor phase transition, and the material expands. After the power is turned off, the phase change fluid 2 produces a vapor-liquid phase transition, and the material shrinks, such as figure 2 As shown, the artificial muscle can produce muscle-like recipro...

Embodiment 2

[0046]The difference between this example and Example 1 is that the thermal conductivity enhancer is different, a flexible phase-change artificial muscle material, including flexible silica gel matrix 1, phase-change fluid 2, thermal conductivity enhancer, heating resistance wire 3 and outer nylon mesh , the flexible silica gel matrix 1 contains thermal conductivity enhancing additives, the phase change liquid 2 is evenly distributed in the flexible silica gel matrix 1 in the form of bubbles, and the thermal conductivity enhancing additives are evenly dispersed in the flexible silica gel matrix 1. Nylon braided mesh is wrapped on the outside, and the resistance wire is energized to generate heat change, which causes the phase change liquid 2 to undergo a liquid-vapor phase change, and the material expands. After the power is turned off, the phase change liquid 2 undergoes a vapor-liquid phase change, and the material shrinks, such as figure 2 As shown, the artificial muscle ca...

The phase change liquid is absolute ethyl alcohol, and the heat conductivity enhancing additive is oxidized graphene or gold nano-particles. The motion pattern of muscle contraction and relaxation is simulated, flexible composite material design and mechanical structure design are organically integrated, and the flexible phase change type artificial muscle material which is capable of working under the low-pressure condition, flexible, small in size and large in deformation is provided.

Description

technical field [0001] The invention relates to an artificial muscle material and a preparation method thereof, in particular to a flexible phase-change artificial muscle material and a preparation method thereof. Background technique [0002] With the development of robots and people's strong demand for intelligent mechanical systems, artificial muscles, which are the key to driving robots and intelligent mechanical systems, have become the focus of research in the field of bionics. Traditional driving methods such as motors, pneumatics, hydraulics, etc. are too large and have limited working conditions to meet the development requirements of future robots. Therefore, new actuation materials have become the focus of research. At present, research on artificial muscle materials mainly focuses on electroactive polymers and phase-change artificial muscles, both of which have large deformation and energy density. [0003] The phase-change artificial muscle is composed of an el...
