Introduce in detail structure and the principle of work of the triboelectricity machine 31 in triboelectricity display device 10 of the present utility model below in conjunction with Fig. 5 a to Fig. 8.
The first structure of triboelectricity machine 31 is as shown in Fig. 5 a and Fig. 5 b.Fig. 5 a and Fig. 5 b show respectively perspective view and the cross-sectional view of the first structure of triboelectricity machine 31.This triboelectricity machine 31 comprises: the first electrode 4, the first high molecular polymer insulation courses 3 that are cascading, and the second electrode 1.Particularly, the first electrode 4 is arranged on the first side surface of the first high molecular polymer insulation course 3; And the Surface Contact friction of the second side surface of the first high molecular polymer insulation course 3 and the second electrode 1 also induces electric charge at the second electrode 1 and the first electrode 4 places.Therefore, the first above-mentioned electrode 4 and the second electrode 1 form two output terminals of triboelectricity machine.
In order to improve the generating capacity of triboelectricity machine, at second side surface (being on the face of relative the second electrode 1) of the first high molecular polymer insulation course 3, further be provided with micro-nano structure 2.Therefore, when the triboelectricity machine is squeezed, apparent surface's contact friction better of the first high molecular polymer insulation course 3 and the second electrode 1, and induce more electric charge at the first electrode 4 and the second electrode 1 place.Because the second above-mentioned electrode 1 is mainly used in and the first high molecular polymer insulation course 3 frictions, therefore, the second electrode 1 also can be referred to as the electrode that rubs.
Above-mentioned micro-nano structure 2 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 insulation course 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 insulation course 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 be selected 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 principle of work of the triboelectricity machine shown in Fig. 5 a and Fig. 5 b.When each layer of this triboelectricity machine is squeezed, the second electrode 1 in the triboelectricity machine produces static charge with the surperficial phase mutual friction of the first high molecular polymer insulation course 3, the generation of static charge can make the electric capacity between the first electrode 4 and the second electrode 1 change, thereby causes electric potential difference occurring between the first electrode 4 and the second electrode 1.Because the first electrode 4 is connected with display screen with the output terminal of the second electrode 1 as the triboelectricity machine, display screen forms the external circuit of triboelectricity machine, between two output terminals of triboelectricity machine, is equivalent to be communicated with by external circuit.When each layer of this triboelectricity machine returns to original state, the built-in potential at this moment be 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 electric potential difference.By repeatedly rubbing and recovering, just can in external circuit, form periodic alternating-current pulse electric signal.
According to inventor's research, find, metal and high molecular polymer friction, the more volatile de-electromation of metal, therefore adopt metal electrode and high molecular polymer friction can improve energy output.Therefore, correspondingly, in the triboelectricity machine shown in Fig. 5 a and Fig. 5 b, the second electrode is because needs are rubbed 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, aldary, kirsite, manganese alloy, nickel alloy, lead alloy, ashbury metal, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungalloy, molybdenum alloy, niobium alloy or tantalum alloy.The first electrode is rubbed owing to not needing, therefore, except the material that can select 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, aldary, kirsite, manganese alloy, nickel alloy, lead alloy, ashbury metal, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungalloy, 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.
