As shown in fig. 3, the bionic friction nano-generator 201 includes: FEP substrate 2011, conductive graphite 2013, PTFE film 2015, sponge pad 2012, and sponge pad 2012. Specifically, the conductive graphite 2013 is attached to the surface of the FEP substrate 2011, and the conductive graphite 2013 is connected to a conductive copper sheet 2014.

Based on the inspired marine kelp sheet structure, the friction nano generator can be divided into three layers from top to bottom, wherein the upper layer material is a PTFE film, the lower layer material is a FEP film, and the FEP film is covered with a copper film. The middle layer is mainly a foam cushion and air sealed in the foam cushion and is used for separating the upper layer electrode material from the lower layer electrode material, so that the upper layer electrode material and the lower layer electrode material can be intermittently contacted and separated to generate charge transfer. When the copper film with the electropositivity and the PTFE film with the electronegativity are mutually contacted and separated, a large amount of charges are accumulated on the flexible friction nano power generation surface at the moment to form an electrostatic field, and the conversion from the fluid kinetic energy to the electric energy of the friction nano power generator is completed.
The preparation materials are as follows: polytetrafluoroethylene (PTFE) film of 0.04-0.06 mm, fluorinated ethylene propylene copolymer (FEP) film of 0.08-0.1 mm, copper film of 0.08-0.12 mm, sponge cushion of 0.8-1.2 mm thickness, etc.

The structure is similar to a sandwich structure, and can be divided into three layers from top to bottom. The upper layer material is PTFE film, which has electronegativity due to high fluorine content and is used as the negative electrode of the friction nano generator; the lower layer material is an FEP film with the thickness of 0.1mm, and a copper film is attached to the FEP film and used as a positive electrode of the friction nano generator. The FEP film has good elasticity, and can provide the restoring force of swinging of the friction nano generator in the flow field under the action of fluid; the middle layer is mainly a foam cushion with the thickness of 1mm and air sealed in the foam cushion, and is used for separating the upper layer electrode material from the lower layer electrode material, so that the upper layer electrode material and the lower layer electrode material can be intermittently contacted and separated to generate charge transfer.

Under the action of the electric field, the easy scaling ions can deviate in different directions in the water system, so that the combination probability is reduced, and the scaling phenomenon is further reduced. It is worth noting that the method is different from the traditional electrostatic antiscaling method, and a power supply device is not required to be additionally added outside; the friction nano generator scale prevention method also different from the partial conceptual form needs various combinations of a generator part, an external amplifying circuit part, a scale prevention electric field part and the like. The friction nano generator array designed by the method can collect electric energy better through proving, an external amplifying circuit part is omitted, and the highly integrated structure certainly improves the application field and reduces the maintenance cost.

Compared with the traditional electric field scale prevention scheme, the method has the advantages that a series of problems of high electric power cost, personal injury due to leakage, circuit faults and the like are avoided.
The invention also provides an anti-scaling experiment method based on the bionic friction nano-generator, which is realized based on the anti-scaling device based on the bionic friction nano-generator and comprises the following steps:
