Abstract

The invention provides an in-situ polymerized surface modified fiber-based friction nano-generator and a preparation method thereof. The in-situ polymerized surface modified fiber-based friction nano-generator is characterized by comprising a friction electropositive nanofiber membrane having in-situ constructed silica nanoparticles (SiO2 NPs) on a surface, and friction electronegative nanofiber membrane having in-situ constructed polytetrafluoroethylenen nanoparticles(PTFE NPs). The surface charge of the friction nano-generator after in-situ polymerized surface modification is expected to increase by 10 to 300%, the short-circuit current is expected to increase by 20 to 300%, and the open circuit voltage is expected to increase by 50 to 300%. The friction nano-generator of the invention has high electric output performance, small volume, simple structure and short preparation process. With the further improvement of its performance, the friction nano-generator will have a broader prospect in the field of wearable electronics.

Description

technical field [0001] The invention belongs to the technical field of nano-energy and friction nano-generator, and in particular relates to a fiber-based friction nano-generator modified by in-situ polymerization and a preparation method thereof. Background technique [0002] With the advancement of science and technology and social development, new smart wearable products such as Apple Watch, Mi Band, and Google Glass have entered people's field of vision one after another. These electronic devices are gradually developing in the direction of miniaturization and portability, which put forward stricter requirements for their energy supply systems. Traditional energy supply devices such as lithium-ion batteries or rechargeable batteries have problems such as large size, rigidity, limited service life, and electrolytes are easy to pollute the environment, making it difficult to meet the development needs of current wearable products. Therefore, the development of a micro ene...
