Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic diagram of a circuit converting unit according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a circuit converting unit according to another embodiment of the present invention.
In the present embodiment, the circuit converting unit includes a shape memory polymer layer 110, a modification layer 120, and a liquid metal 130. The shape memory polymer layer 110 is a single-layer structure, and a channel 111 is formed inside the shape memory polymer layer. In this example, the shape memory polymer was prepared by chemical synthesis.
Shape Memory Polymers (SMP for short) refer to a polymer material that can be restored to its original state by external conditions (such as heat, electricity, light, chemical stimulation, etc.) after an original Shape of a product is changed and fixed under the condition of external force. At present, shape memory polymers are widely used as a novel intelligent material in various fields such as MEMS, medical treatment, bioengineering and the like. Compared with shape memory alloy, the shape memory polymer as a novel high molecular functional material has the characteristics of light weight, large deformation range, easy industrial processing, economic price and the like.
Besides the advantage of non-toxicity, the liquid metal also has the characteristics of low viscosity, adjustable conductivity, difficult evaporation and the like. Meanwhile, the liquid metal has a faster thermal diffusion speed than the solid metal and is not easily affected by local environmental temperature mutation. At present, two liquid metals which are widely used are Galinstan and EGaln. Galinstan is composed of three elements of Ga, In and Sn. Galinstan has been applied to thermometers, coolants, and MEMS devices as a liquid metal material that can replace mercury. Galinstan is easily oxidized in air, so the packaging process is very important to the performance of the device during the manufacturing process. EGaln is eutectic alloy with GaLinstan, consists of Ga and In, and can be used for preparing electronic devices and circuits. Meanwhile, the viscosity and the conductivity of the liquid metal can be regulated and controlled by doping a small amount of gallium oxide, and the surface tension can be effectively reduced.
It will be appreciated that the shape memory polymer layer 110 is rigid and capable of self-supporting when subjected to constant external conditions.
In this embodiment, the shape memory polymer layer 110 is a single-layer structure, a channel 111 is formed inside the shape memory polymer layer, and the liquid metal 130 is enclosed in the channel 111 to form a conductive path. Specifically, the channel 111 is formed by perforating the shape memory polymer layer 110, and the channel 111 penetrates the shape memory polymer layer 110. It will be appreciated that where the channels 111 extend through the shape memory polymer layer 110, baffles may be provided at the exit and entrance of the channels to enclose the liquid metal 130 within the shape memory polymer layer. In other embodiments, the channel 111 may not extend through the shape memory polymer layer 110, i.e., a portion of the shape memory polymer layer 110 is left at both ends of the channel 111 to seal the liquid metal 130.
Specifically, the shape memory polymer is a chemical stimulation deformable polymer, and can change shape according to the change of the pH value of the environment, the shape of the channel 111 changes according to the change of the shape memory polymer, and the conductive path formed by the liquid metal 130 changes along with the change of the shape of the channel 111, so that when the shape of the shape memory polymer layer 110 changes, the conductive path formed by the liquid metal 130 also changes, and the function also changes.
Specifically, the chemically-deformable polymer may be one or more of polyampholyte hydrogel, polyacrylamide, polyacrylic acid-polyethyleneimine copolymer, graphene and chitosan composite hydrogel material.

In other embodiments, the liquid metal 130 can be enclosed in the shape memory polymer layer 110 by other methods, such as enclosing the liquid metal 130 in the shape memory polymer layer 110.
Specifically, when the shape memory polymer is an electro-deformable polymer, the shape of the shape memory polymer layer changes with a change in voltage. Illustratively, the shape memory polymer can be one or more of a carbon nanotube-polyurethane composite electric response material, a carbon black-polyhexamethylene lactone composite electric response material or a copolymer magnetic response material formed by coupling ferroferric oxide-doped polytetramethylene ether glycol with diisocyanate.

Illustratively, the shape memory polymer can be one or more of a polyvinyl alcohol PVA monomolecular film with azobenzene side chains, a cross-linked polyethylacrylate material or a 6Az10-PAA and nylon 66 film material. In other embodiments, the photo-deformable polymer layer may be made of other materials, so long as the shape of the shape memory polymer layer changes with the change of the wavelength of light.

In the present embodiment, the modification layer 120 is disposed on the inner surface of the shape memory polymer layer 110 by Physical Vapor Deposition (PVD). In other embodiments, the modification layer 120 may be disposed on the inner surface of the shape memory polymer layer 110 by Chemical Vapor Deposition (CVD), Atomic Layer Deposition (ALD), spray coating, spin coating, or the like. In this embodiment, the modified layer 120 is a metal inorganic layer, such as an aluminum oxide or zinc oxide thin film having micropores. In other embodiments, the modified layer 120 may be a polymer organic layer, such as a micrometer-sized Polyvinyl chloride (PVC) particle layer, and the modified layer 120 may have a contact surface for controlling a contact angle of the liquid metal, so as to form a surface with a controllable contact angle of the liquid metal.
In this embodiment, the circuit converting unit further includes a liquid storage region disposed in the shape memory polymer layer 110, and when the shape memory polymer layer 110 is deformed, the liquid storage region can accommodate the liquid metal 130 extruded by the shape memory polymer layer 110.

In the electronic device of the embodiment shown in fig. 3, the electronic device comprises an output terminal, a receiving terminal and the above circuit switching unit, wherein the receiving terminal and the output terminal extend into the shape memory polymer layer 110 through the solid wire 140 and can be electrically communicated with the liquid metal 130, and the shape change of the shape memory polymer layer 110 can control the connection and disconnection between the output terminal and the receiving terminal. When the wavelength of the ambient light of the shape memory polymer layer 110 is changed, the shape memory polymer layer 110 deforms and extrudes, the shape of the channel 111 changes along with the deformation and extrusion of the shape memory polymer layer 110, the liquid metal 130 is distributed in the channel 111 of the shape memory polymer layer 110, at this time, the signal output end is conducted with the signal receiving end A through the liquid metal 130, the signal receiving end B is blocked, and no signal is input.
The electronic device of the embodiment shown in fig. 4 is a state of the electronic device of the embodiment shown in fig. 2 after changing the wavelength of the ambient light, when the wavelength of the ambient light of the shape memory polymer layer 110 is changed, the shape memory polymer layer 110 deforms and presses along with the change of the wavelength of the ambient light, the channel 111 changes the shape along with the deformation and pressing of the shape memory polymer layer 110, the liquid metal 130 is distributed in the channel 111 of the shape memory polymer layer 110, the connection mode is changed along with the deformation and pressing of the shape memory polymer layer 110, at this time, the signal output end and the signal receiving end B are conducted through the liquid metal 130, and the signal receiving end a is blocked.
