During body electrochemical window, Bucky gel drivers show stable output displacement.
Specifically, present invention additionally comprises following steps：
1st, prepared by the ionic polymer metal composite material (NCNCs/Nafion-IPMC) of nitrogen carbon dope nanocages enhancing (is somebody's turn to do
Method is one kind in the preparation method of ionic electroactive polymer)：
1) nitrogen carbon dope nanocages are by MgO template methods reported in the literature, pyridine obtain as presoma (Zhao J,
Lai H,Lyu Z,Jiang Y,Xie K,Wang X,Wu Q,Yang L,Jin Z,Ma Y,Liu J,Hu
Z.Hydrophilic hierarchical nitrogen-doped carbon nanocages for ultrahigh
supercapacitive performance.Adv Mater 2015；27:3541-3545.Chen S,Bi J,Zhao Y,
Yang L,Zhang C,Ma Y,Wu Q,Wang X,Hu Z.Nitrogen-doped carbon nanocages as
efficient metal-free electrocatalysts for oxygen reduction reaction.Adv Mater
2012；24:5593-5597.), its pattern is as shown in Figure 1.
2) nitrogen carbon dope nanocages are dispersed in Nafion solution, content is respectively 0.1wt% and 0.2wt%, magnetic
Power rotor stirs 2h, and ultrasonic disperse 1h is to obtain homogeneous solution.
3) solution is poured onto silicon rubber mould, is placed in baking box, 16h is dried at 70 DEG C, is annealed at 150 DEG C
8min,
Obtain the nitrogen carbon dope nanocages enhancing Nafion membrane (NCNCs/Nafion that content is respectively 0.1wt% and 0.2wt%
Film), pure Nafion membrane can be obtained using same method by being not added with nitrogen carbon dope nanocages.
The section of pure Nafion membrane and NCNCs/Nafion film is as shown in Figure 2, it can be seen that size range~100nm to 1 μ
M nitrogen carbon dope nanocages are uniformly distributed in 0.1wt% NCNCs/Nafion films (Fig. 2 c~2f), and nitrogen carbon dope nanocages are reunited
In 0.2wt% NCNCs/Nafion films (Fig. 2 g), and there are a large amount of nano cages to be deposited on Nafion membrane bottom (Fig. 2 h), this
Interface bond strength can be reduced, causes the asymmetric ion-exchange capacity of Nafion membrane, forms asymmetrical metal electrode (Fig. 2 h
With Fig. 4 b) and sheet resistance, the reason for this is also 0.2wt% NCNCs/Nafion-IPMC output displacements asymmetric (Fig. 5 b).
Fig. 3 give pure Nafion membrane and content be respectively 0.1wt% and 0.2wt% NCNCs/Nafion films stretching
Curve, the power broken are respectively 22,30.7,36.3N, and their tensile strength is respectively 15.7,24.5,27.9MPa,
The tensile strength of 0.1wt% and 0.2wt% NCNCs/Nafion films is 1.6 times of pure Nafion membrane respectively, 1.8 times, is stretched
Curve also shows that the addition of nitrogen carbon dope nanocages adds strain, and this is due to improved interface bond strength and Nafion membrane
Microfacies pattern.Because the carbon atom after being modified in covalent bond nitrogen carbon dope nanocages can be tightly combined with Nafion, effectively promote
Enter plus load and be transferred to nitrogen carbon dope nanocages, the sliding phenomenon near crystal boundary is avoided, so as to improve interface bond strength；Simultaneously
Due to chemical bond different between nitrogen carbon dope nanocages and Nafion, nitrogen carbon dope nanocages are pushed near crystal boundary, in nitrogen carbon dope
Nanocages and crystal boundary form physics and prick nail effect, improve grain boundary intensity.It is worth noting that, 0.1wt%NCNCs/
The strain of Nafion membrane will be slightly higher than 0.2wt%NCNCs/Nafion films, further demonstrate 0.1wt% NCNCs/
Nitrogen carbon dope nanocages are uniformly distributed in Nafion membrane, and nitrogen carbon dope nanocages are reunited in 0.2wt% NCNCs/Nafion films.
4) deposited by the method for chemical plating in nitrogen carbon dope nanocages Nafion membrane both sides platinum (He Q S, Yu M,
Zhang X Q,Dai Z D.Electromechanical performance of an ionic polymer-metal
composite actuator with hierarchical surface texture.Smart Materials and
Structures,2013,22,055001(11pp).)；
5) laminated film will be obtained to be soaked in 1.5M LiCl solution, toasts 3d at 30 DEG C in baking box, carry out Li ions
Exchange, obtain the ionic polymer metal composite material of nitrogen carbon dope nanocages enhancing.
Fig. 4 gives 0.1wt% NCNCs/Nafion-IPMC SEM pictures, and Fig. 4 a give section SEM pictures, by
Nafion membrane and the platinum metal layer of both sides (thickness is~12 μm, Fig. 4 b) composition, symmetrical metal level ensure that 0.1wt%'s
The symmetry of NCNCs/Nafion-IPMC output displacements.Fig. 4 c show and are preferably combined between polymer and metal, platinum grain
It is deeply embedded into Nafion, without obvious interface, illustrates that electrode infiltrates into polymer well.Electrode is can be seen that from Fig. 4 d
Platinum particle diameter be evenly distributed on 50-200nm.
IPMC is cut into 20mm × 5mm (long × wide), tests the driving behavior such as displacement and power, as shown in Figure 5.Fig. 5 a and
5b is given under sinusoidal voltage (1.5,2.5,3.0V, 0.1Hz) input, pure Nafion-IPMC's and NCNCs/Nafion-IPMC
Maximum displacement.It can be seen that NCNCs/Nafion-IPMC displacement significantly improves, particularly 0.1wt%NCNCs/Nafion-
IPMC displacement is 1.6~2 times of pure Nafion.This hole that be attributed to the fact that on nano cages provides Ion transfer and hydrone
The space of storage, adds water content, so as to generate big output displacement.Fig. 5 b give sinusoidal voltage (2.5,0.1Hz)
Harmonic displacement response under input, pure Nafion-IPMC and 0.1wt%NCNCs/Nafion-IPMC show symmetrical displacement
Response, this is due to equally distributed nitrogen carbon dope nanocages (Fig. 2 c~2f) and symmetrical electrode layer in Nafion membrane；But by
Reunite in nitrogen carbon dope nanocages and deposit (Fig. 2 g and 2h), 0.2wt%NCNCs/Nafion-IPMC shows obvious asymmetry
Displacement.Fig. 5 c are given under sinusoidal voltage (1.5,2.5,3.0V, 0.1Hz) input, pure Nafion-IPMC and NCNCs/
Nafion-IPMC maximum output power.It can be seen that NCNCs/Nafion-IPMC power significantly improves, particularly 0.1wt%
NCNCs/Nafion-IPMC power is 1.6~2 times of pure Nafion, this be due to nitrogen carbon dope nanocages add tensile strength,
Modulus of elasticity and water content (table 1).
Because nitrogen carbon dope nanocages are deposited on Nafion membrane bottom, 0.2wt%NCNCs/Nafion-IPMC power output will
Less than 0.1wt%NCNCs/Nafion-IPMC.Fig. 5 d give the maximum that sinusoidal voltage (2.5,0.1Hz) inputs lower 5 cycles
Power output.
The characteristic of 1 pure Nafion membrane of table and the Nafion membrane of nitrogen carbon dope nanocages enhancing
2nd, prepared by Bucky gel drivers：
The specific preparation process of chitosan polymer multi-walled carbon nanotube-ionic liquid gel electrode B ucky gel drivers
It is as follows：
Step 1) MWCNT/BMIBF4The preparation of electrode film：The acetic acid that 50mg Chitosan powders are added to 10ml 2% is molten
In liquid, 30min is stirred at 60 DEG C, to form uniform solution, 80mg MWCNT and 190mg BMImBF4It is added to above-mentioned
Ultrasonic 30min under condition of ice bath in solution, ultrasound after mixed solution be poured onto in PDMS moulds, be placed in baking box and toasted at 60 DEG C
12h, obtain the MWCNT/BMIBF that MWCNT contents are 15wt%4Electrode film；
The preparation of step 2) chitosan ionic liquid electrolyte film：The acetic acid that 100mg chitosans are added to 5ml 2% is molten

Chitosan ion liquid polymer film；
The preparation of three layers of driver of step 3)：Using metallic phase sample inlaying machine XQ-2B hot pressing electrode film and polymer thin
Film, temperature are 70 DEG C, and it is MWCNT/BMIBF to obtain both sides4Electrode film, centre are chitosan ion liquid polymer films
Bucky gel drivers, its section SEM is as shown in fig. 6, Fig. 7 gives Bucky gel drivers in voltage 4,5,6,7V, frequency
Output displacement under rate 0.1Hz, with the increase of voltage, output displacement gradually increases, and illustrates that the driver has at lower voltages
There is controllability.Compared with traditional IPMC, the internal drive is the cation BMI of ionic liquid+With anion BF4 -Migration,
Under electric signal effect, cation BMI+Migrate to driver negative pole end, anion BF4 -Migrate to driver anode tap, due to
Steric effect, the relatively macrocation expansion of negative pole end accumulation cause to bend to anode more than the smaller anion of anode tap accumulation
Deformation, therefore migration is participated in without hydrone, in the absence of the Electrolysis of water, it is less than the electrochemistry of ionic liquid in driving voltage
When window, driver shows preferable steady operation ability, and output displacement substantially remains in certain level, Fig. 7 a and 7b
The output displacement of middle driver is not decayed after 600s, in Fig. 7 c the displacement of driver initial displacement is kept after 600s
The displacement of driver keeps the 50% of initial displacement after 600s in 83%, Fig. 7 d, and this is due to input voltage in Fig. 7 c and 7d
It is many higher than the electrochemical window of ionic liquid, cause ionic liquid unstable, generate electrochemical reaction so that participate in migration
Ion gradually decrease, output displacement has been decayed.
Chitosan polymer graphene (GS)-ionic liquid (BMIBF4) gel electrode Bucky gel drivers specific system
Standby step is as follows：
Step 1) GS/BMIBF4The preparation of electrode film：50mg Chitosan powders are added to 10ml 2% acetic acid solution
In, 30min is stirred at 60 DEG C, to form uniform solution, 80mg GS and 190mg BMImBF4It is added in above-mentioned solution
Ultrasonic 30min under condition of ice bath, ultrasound after mixed solution be poured onto in PDMS moulds, be placed in baking box and toast 12h at 60 DEG C, obtain
Obtain the GS/BMIBF that GS contents are 15wt%4Electrode film；
The preparation of step 2) chitosan ionic liquid electrolyte film：The acetic acid that 100mg chitosans are added to 5ml 2% is molten
In liquid, 30min is stirred at 60 DEG C, to form uniform solution, 830mg glycerine and 200mg BMImBF4Add above-mentioned molten
Liquid, 30min is stirred at 60 DEG C, the mixed solution of acquisition pours into PDMS moulds, is placed in baking box and toasts 8h at 60 DEG C, obtains
Chitosan ion liquid polymer film；
The preparation of three layers of driver of step 3)：Using CARVER hot presses hot pressing Graphene electrodes film and polymer thin
Film, temperature are 70 DEG C, and it is Graphene electrodes film to obtain both sides, and centre is the Bucky of chitosan ion liquid polymer film
Gel drivers, its section SEM are as shown in Figure 8.Obtained in the case where sinusoidal voltage amplitude is 4,5,6,7V frequency 0.1Hz input signal
Strain be respectively 0.032%, 0.038%, 0.063%, 0.1%, the result can surpass with the flexible class of the report such as Torop
The carbon electrode driver strain value (0.019%~0.359%) of level capacitor quite (Torop J, Palmre V, Arulepp
M,Sugino T,Asaka K,Aabloo A.Flexible supercapacitor-like actuator with
carbide-derived carbon electrodes.Carbon,2011,49:3113-9.).In driving sinusoidal voltage amplitude
For 4 and 5V, the output displacement of the novel ionic driver is not decayed when frequency is 0.1Hz, or even also has some increases to become
Gesture, this is due to the problem of hydrolysis is not present in internal drive, and the graphene membrane electrode structure of sheet effectively prevents
The leakage of ionic liquid.When driving voltage is higher than ionic liquid BMImBF4Electrochemical window (~4.7V), in sinusoidal voltage
The displacement of driver keeps 82%, 51% respectively after 600s when amplitude is 6,7V, as shown in Figure 9.It would therefore be desirable to control
The size of driving voltage avoids ionic liquid from becoming unstable near electrochemical window, to keep ionic driver stable
Driveability.
