Have the advantages that weak stimulation-strong response, few addition-effect, drive condition greatly are gentle；And soft material driver particularly gel flooding
Dynamic development of the device in intelligent device field is of increasing concern.
In the research of gel driver, shape memory gel driver can be returned to original-shape from temporary shapes,
For a kind of rather extensive gel driver of research at present.But each driving for the shape memory gel driver reported at present
Cycle is required for that gel first is fixed as into a temporary shapes with external force（ACS Appl. Mater. Interfaces 2016,
8, 12384−12392；Macromol. Mater. Eng. 2017, 302, 1600359）, and can not realize that gel is spontaneous
Changed between temporary shapes and original-shape, therefore the mode of operation of gel driver is more complicated.Meanwhile, report at present
Dopamine gel mechanical strength is relatively low, it is impossible to bear larger stretching, compression or repeated deformation etc., and dopamine is constrained significantly and is coagulated
Application of the glue in field of drivers.
From dopamine and Fe3+Complexing inspired, based on shape memory gel driver, we are creative
Ground devise it is a kind of can spontaneous driving dopamine gel driver, i.e., dopamine Methacrylamide and hydrophilic monomer are total to
It is poly- to obtain gel, then by gel in Fe3+Immersion treatment in solution, reusing external force makes the gel obtain temporary shapes, by it
It is put into alkaline solution and fixes this temporary shapes；The gel with temporary shapes is put into acid solution again, temporary shapes can
Original-shape is reverted to, that is, obtains dopamine gel driver.The driver can make it in temporary shapes by controlling pH value of solution
Spontaneous change is to produce driving between original-shape, and this process may be repeated.
The content of the invention
In view of the shortcomings of the prior art, the invention provides it is a kind of can spontaneous driving dopamine gel driver and its system
Preparation Method and type of drive.
The dopamine gel driver of the present invention is total to by dopamine Methacrylamide and hydrophilic acrylamide class monomer
Poly- obtained gel, in Fe3+Enable in alkaline solution the temporary shapes become by external force solid in solution after immersion treatment
It is fixed, dopamine gel driver is obtained, the dopamine gel driver can not apply external force effect by controlling solution ph
In the case of, making it, spontaneous change is to produce driving between temporary shapes and original-shape, and this process may be repeated.

More than one, concentration is 0.01 ~ 0.5 mol/L；The time of the immersion treatment is 10 ~ 60 s.
Further, step（2）The alkaline solution is pH>9 NaOH solution, KOH solution, Ca (OH)2Solution or
Ba(OH)2Solution；The temporary shapes are the shapes different from gel original-shape；The regular time is 10 ~ 60 s.
As made from above-described preparation method it is a kind of can spontaneous driving dopamine gel driver.
It is above-described it is a kind of can spontaneous driving dopamine gel driver type of drive, comprise the following steps：
（1）Dopamine gel driver is put into acid solution and soaked, temporary shapes can revert to original-shape；
（2）The dopamine gel driver for reverting to original-shape is placed into alkaline solution and soaked, the dopamine gel
Driver can in the case where no external force is acted on it is spontaneous become again before temporary shapes；
（3）Dopamine gel driver with temporary shapes is subjected to step again（1）Operation, dopamine gel driving
Device can revert to original-shape, and the dopamine gel driver for reverting to original-shape is carried out into step again（2）Operation, institute
State dopamine gel driver in the case that no external force is acted on it is spontaneous become again before temporary shapes；That is, step is passed through
（1）And step（2）Continuously repeat operation, it is possible to achieve by controlling solution ph, do not apply external force effect in the case of,
Make the dopamine gel driver in the solution between temporary shapes and original-shape spontaneous change to produce driving.
Further, step（1）The acid solution is pH<5 HCl solution, H2SO4Solution or HNO3Solution；It is described
