Embodiment 1

[0038] Materials: dimethylglyoxime (DMG, 98%), acetone (99.7%) were purchased from Sinopharm Chemical Reagent (China). Polytetrahydrofuran diol (PTMG, Mn=1000 g mol-1) was purchased from Aladdin (China). Diethylenetriamine (DETA, 99.0%) was purchased from Alfa Aesar (China). Diphenylmethane diisocyanate (MDI, 2,4'-MDI / 4,4'-MDI=50 / 50, 99.6%) was purchased from Wanhua Chemical (China). Chloroform (99.8%) was purchased from Yonghua Chemical (China). Reagents were used without further purification unless otherwise stated.

[0039] Synthesis of PDOUs

[0040] Add polytetrahydrofuran glycol (PTMG) into the reaction flask, raise the temperature to 110°C, and vacuumize for 2 hours to remove the adsorbed water in the polytetrahydrofuran glycol. The vacuum was then removed, and a nitrogen balloon was inserted to maintain N 2 Atmosphere, after slowly adding diphenylmethane diisocyanate (MDI) at 110°C, N 2 Reaction under atmosphere for 2h. Then keep N 2 The whole system was lowere...

Abstract

The invention relates to a reconfigurable driver based on a self-healing elastomer and a preparation method of the reconfigurable driver. The reconfigurable driver is composed of a self-healing non-crosslinked PDOU film NPDOU and a crosslinked PDOU film CPDOU. According to the reconfigurable soft driver based on the intrinsic type self-healing polyurethane elastomer, the PDOU elastomers with different crosslinking degrees show different responsiveness to a solvent, and seamless healing can be achieved; and the assembled driver / robot can be reprogrammed through simple cutting and reassembling without any external stimulation so as to display various driving modes, and a simple, powerful and universal path is laid for constructing a soft robot with a complex structure.

Description

technical field [0001] The invention belongs to the field of soft actuators, in particular to a reconfigurable actuator based on self-healing elastic body and a preparation method thereof. Background technique [0002] Compared with rigid drives, soft drives have the advantages of low cost, low density, high degree of freedom, high adaptability, and good human-computer interaction interface. They are widely used in soft robots, artificial muscles, micro-equipment, flexible sensing and other fields. . Actuators are the key components for generating motion in soft robots, which makes them crucial to the development of soft robots and have received extensive attention. Smart actuated materials can exhibit reversible shape transitions in response to stimuli such as solvents, heat, light, electric field, magnetic field, humidity, etc. The anisotropic structure is key to the actuator's ability to deform or move in response to stimuli. Currently available methods for preparing a...
