Friction generator of the invention is used for the growth application of crops, has facilitation to the growth of crops.It will
Friction generator is placed on soil, and protein film makes friction electricity in the side of contact soil, and to the friction generator applied force
It approaches, leave or Relative sliding between negative layer and protein film, that is, be applied with mechanical energy, and then life is produced to crops
The long electric field promoted.
As shown in figure 4, friction generator of the invention can there are four types of operating mode, perpendicular contacts-clastotype, level
Sliding-modes, single electrode mode and independent layer model.
Perpendicular contact-clastotype: in this structure, protein film stacks face-to-face with the electric negative layer that rubs, each
Back side adherency or be coated with electrode.The electric negative layer that rubs contacts with each other with protein film, and it is opposite to form symbol in two contact surfaces
Surface charge.When the two surfaces are separated due to external force, centre will form a small the air gap, and
Induced electricity potential difference is formed between two electrodes.When two electrodes are linked together by load, electrons are by loading from one
A electrode flows to another electrode, forms a reversed potential difference and comes equilibrium electrostatic field.When in rub electric negative layer and protein film
Between the air gap closure when, the potential difference disappearance formed by triboelectric charge, electrons flow back.It constantly recycles in this way, with
The electric field of time change will drive electrode of the electronics at the electrode of albumen back of the membrane and the electric negative layer back side that rubs to flow back and forth, thus
Generate alternating current.
Horizontal sliding-modes: the initial identical and protein film of structure vertical contact-clastotype of this mode with rub
It wipes electric negative layer to stack face-to-face, their own back side adheres to or is coated with electrode, and mutually interconnects between two electrodes by external circuit
It connects.When protein film and the electric negative layer that rubs contact, the phase of the horizontal direction parallel with surface can be taken place along between two kinds of materials
To sliding, triboelectric charge can also be generated on both surfaces in this way.In this way, just will form polarization in the horizontal direction, can drive
Dynamic electronics flows between the electrode of albumen back of the membrane and the electrode at the electric negative layer back side that rubs, to balance the quiet of triboelectric charge generation
Electric field.It can produce one with closure by periodically sliding separation and exchange output.Here it is slidingtype friction nanometer generatings
The basic principle of machine, and this sliding can exist in a variety of forms, including planar slide, cylindrical slid you and disk sliding
Deng.
Single electrode operating mode: above-mentioned protein film and the electric negative layer that rubs are combined, and in the back of protein film
Surface or the electric negative layer back surface that rubs arrange one layer of electrode again, and electrode is grounded, and thus constitutes friction generator.When upper
The electric negative layer of friction in portion closer to or farther from lower part protein film when or top the electric negative layer opposing lower portions of friction protein film
When frictional movement, local field distribution will change, and electron exchange can be occurred in this way by descending between electrode and the earth, to balance electricity
Potential change on extremely.
Independent layer model: albumen back of the membrane adhere to or plate two disjunct symmetry electrodes, the size of electrode and its
Spacing can suitable control, and two electrodes are connected by external circuit.When the electric negative layer that rubs is in two electrodes of albumen film surface
Between when moving reciprocatingly, the variation of potential difference can be generated between two electrodes, and then electronics is driven to be supported on by external circuit
It is flowed back and forth between two electrodes, with the variation of equilibrium potential difference.
Compared with the prior art, the present invention has the following beneficial effects:
First on material, this biomaterial of vegetable protein from being not introduced into friction generator field, vegetable protein due to
There are the groups such as many hydroxy aminos on surface, has stronger electron donation, is a kind of candidate that friction nanometer power generator is natural
Material；
Secondly, Plant Protein Films preparation process is simple compared with other biological material, and it is from a wealth of sources, and its price is low
It is honest and clean, often it is disposed of as scrap；
Finally, using the space for being applied to agricultural for the first time as mulch based on the friction nanometer power generator of vegetable protein of preparation
In electric field growth-promoting system, using bean seedlings as test object, good technical effect has been obtained as a result, therefore with very big before
Scape.
The present invention innovatively using vegetable protein as friction electric material, various vegetable proteins is used to be charged by friction row
For, including rice protein, peanut protein isolate, soybean protein isolate, wheat gluten and zeins, innovatively utilize
Friction nanometer power generator creates space electric field promotion system as biodegradable mulch, for agricultural, and achieves considerable
Significant technological achievement.
