Structure and the operation principle of the nano friction generator in electricity generation system will be introduced in detail below.
The first structure of nano friction generator is as shown in Fig. 6 a and Fig. 6 b.Fig. 6 a and Fig. 6 b show respectively perspective view and the cross-sectional view of the first structure of nano friction generator.This nano friction generator comprises: the first electrode 61, the first high molecular polymer insulating barriers 62 that are cascading, and the second electrode 63.Particularly, the first electrode 61 is arranged on the first side surface of the first high molecular polymer insulating barrier 62; And the Surface Contact friction of the second side surface of the first high molecular polymer insulating barrier 62 and the second electrode 63 also induces electric charge at the second electrode 63 and the first electrode 61 places.Therefore, the first above-mentioned electrode 61 and the second electrode 63 form two outputs of nano friction generator.
In order to improve the generating capacity of nano friction generator, at second side surface (being on the face of relative the second electrode 63) of the first high molecular polymer insulating barrier 62, be further provided with micro-nano structure 64.Therefore, when nano friction generator is squeezed, apparent surface's contact friction better of the first high molecular polymer insulating barrier 62 and the second electrode 63, and induce more electric charge at the first electrode 61 and the second electrode 63 places.Because the second above-mentioned electrode 63 is mainly used in and the first high molecular polymer insulating barrier 62 frictions, therefore, the second electrode 63 also can be referred to as the electrode that rubs.
Above-mentioned micro-nano structure 64 specifically can be taked following two kinds of possible implementations: first kind of way is that this micro-nano structure is micron order or nano level very little concaveconvex structure.This concaveconvex structure can increase frictional resistance, improves generating efficiency.Described concaveconvex structure can directly form when film preparation, and method that also can enough polishings makes the surface of the first high molecular polymer insulating barrier form irregular concaveconvex structure.Particularly, this concaveconvex structure can be the concaveconvex structure of semicircle, striated, cubic type, rectangular pyramid or the shape such as cylindrical.The second way is, this micro-nano structure is the poroid structure of nanoscale, now the first high molecular polymer insulating barrier material therefor is preferably Kynoar (PVDF), and its thickness is the preferred 1.0mm of 0.5-1.2mm(), and the face of its relative the second electrode is provided with a plurality of nano-pores.Wherein, the size of each nano-pore, width and the degree of depth, can select according to the needs of application, and preferred nano-pore is of a size of: width is that 10-100nm and the degree of depth are 4-50 μ m.The quantity of nano-pore can output current value and magnitude of voltage as required be adjusted, and preferably these nano-pores are that pitch of holes is being uniformly distributed of 2-30 μ m, and preferred average pitch of holes is being uniformly distributed of 9 μ m.
Lower mask body is introduced the operation principle of the nano friction generator shown in Fig. 6 a and Fig. 6 b.When each layer of this nano friction generator is squeezed, the second electrode 63 in nano friction generator produces electrostatic charge with the surperficial phase mutual friction of the first high molecular polymer insulating barrier 62, the generation of electrostatic charge can make the electric capacity between the first electrode 61 and the second electrode 63 change, thereby causes occurring electrical potential difference between the first electrode 61 and the second electrode 63.Because the first electrode 61 is connected with energy storage device with the output of the second electrode 63 as nano friction generator, energy storage device forms the external circuit of nano friction generator, between two outputs of nano friction generator, is equivalent to be communicated with by external circuit.When each layer of this nano friction generator returns to original state, the built-in potential being at this moment formed between the first electrode and the second electrode disappears, and now between Balanced the first electrode and the second electrode, will again produce reverse electrical potential difference.By repeatedly rubbing and recovering, just can in external circuit, form the periodic alternating-current pulse signal of telecommunication.
According to inventor's research, find, metal and high molecular polymer friction, the more volatile de-electromation of metal, therefore adopts metal electrode and high molecular polymer friction can improve energy output.Therefore, correspondingly, in the nano friction generator shown in Fig. 6 a and Fig. 6 b, the second electrode is because needs rub as friction electrode (being metal) and the first high molecular polymer, therefore its material can be selected from metal or alloy, and wherein metal can be Au Ag Pt Pd, aluminium, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; Alloy can be aluminium alloy, titanium alloy, magnesium alloy, beryllium alloy, copper alloy, kirsite, manganese alloy, nickel alloy, lead alloy, ashbury metal, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungsten alloy, molybdenum alloy, niobium alloy or tantalum alloy.The first electrode rubs owing to not needing, therefore, except can selecting the material of above-mentioned the second electrode of enumerating, other materials that can make electrode also can be applied, that is to say, the first electrode is except being selected from metal or alloy, and wherein metal can be Au Ag Pt Pd, aluminium, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; Alloy can be outside aluminium alloy, titanium alloy, magnesium alloy, beryllium alloy, copper alloy, kirsite, manganese alloy, nickel alloy, lead alloy, ashbury metal, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungsten alloy, molybdenum alloy, niobium alloy or tantalum alloy, can also be selected from the nonmetallic materials such as indium tin oxide, Graphene, nano silver wire film.
