Embodiment 1

[0030] Two kinds of nanofiber networks, polyamide 6 and polyacrylonitrile, were deposited on the surface of breathable cotton fabric by electrospinning to obtain moisture absorption and perspiration fabric. The spinning parameters of polyamide 6 are: 12wt% spinning solution concentration (formic acid is used as solvent), the spinning voltage is 20kV, the spinning distance is 15cm, and the advancing speed is 0.2mL / h; the spinning parameters of polyacrylonitrile are : 6wt% spinning solution concentration (N,N-dimethylformamide as solvent), spinning voltage of 15kV, spinning distance of 15cm, and advancing speed of 0.5mL / h. Polytetrafluoroethylene fiber non-woven fabric and polyamide 6 fiber non-woven fabric were selected as friction negative and friction positive fabrics respectively. Moisture-wicking fabrics, conductive nickel-copper fabrics, and frictional polar fabrics were cut with scissors, each having a size of 4×6 cm. The three kinds of fabrics are superimposed one by on...

Embodiment 2

[0032] Two kinds of nanofiber networks, polyamide 6 and polyacrylonitrile, were deposited on the surface of breathable cotton fabric by electrospinning to obtain moisture absorption and perspiration fabric. The spinning parameters of polyamide 6 are: 20wt% spinning solution concentration (formic acid is used as solvent), the spinning voltage is 20kV, the spinning distance is 15cm, and the advancing speed is 0.2mL / h; the spinning parameters of polyacrylonitrile are : 16wt% spinning solution concentration (N,N-dimethylformamide as solvent), spinning voltage of 15kV, spinning distance of 15cm, and advancing speed of 0.5mL / h. Polyvinylidene fluoride non-woven fabrics and nylon non-woven fabrics were selected as friction negative and friction positive fabrics, respectively. Moisture-wicking fabrics, conductive nickel-copper fabrics, and frictional polar fabrics were cut with scissors, each having a size of 4×6 cm. The three kinds of fabrics are superimposed one by one, and the ele...

Embodiment 3

[0034]Two kinds of nanofiber networks, polyamide 6 and polyacrylonitrile, were deposited on the surface of breathable polyester fabric by electrospinning to obtain moisture absorption and perspiration fabric. The spinning parameters of polyamide 6 are: 20wt% spinning solution concentration (formic acid is used as solvent), the spinning voltage is 20kV, the spinning distance is 15cm, and the advancing speed is 0.2mL / h; the spinning parameters of polyacrylonitrile are : 16wt% spinning solution concentration (N,N-dimethylformamide as solvent), spinning voltage of 15kV, spinning distance of 15cm, and advancing speed of 0.5mL / h. Polytetrafluoroethylene non-woven fabrics and polylactic acid non-woven fabrics were selected as friction negative and friction positive fabrics, respectively. Moisture-wicking fabrics, conductive carbon cloths, and frictional polar fabrics were all cut with scissors in a size of 4×6 cm. The three kinds of fabrics are superimposed one by one, and the elect...

Abstract

The invention relates to a friction power generation textile with moisture absorption and perspiration-discharging functions and a preparation method thereof. The friction power generation textile comprises independent textile units, wherein the textile units comprise moisture absorption and perspiration-discharging fabrics, conductive fabrics and friction polar fabrics. The design of the full fabric porous structure ensures the air permeability and moisture permeability of the power generation fabric. When friction surfaces of two pieces of textiles are in contact separation, milliwatt outputpower can be produced. When a human body is sweating, the electrical output power may not be significantly reduced, and can be used to drive common wearable electronic equipment. The friction power generation textile with moisture absorption and perspiration-discharging functions has good flexibility, washability, good air permeability and moisture permeability and good wearing comfort.

Description

technical field [0001] The invention belongs to the field of generators and their preparation, and in particular relates to a triboelectric power generation textile with moisture absorption and perspiration function and a preparation method thereof. Background technique [0002] With the rapid development of the flexible electronics industry, people have put forward higher demands on the user experience of electronic products. The current wearable portable power supply faces major challenges in terms of safety, practicality and comfort. Flexible rechargeable batteries and supercapacitors are implanted in clothing, but the safety and stability of these devices can be greatly compromised when the clothing is repeatedly flexed. Flexible photovoltaic cells can only work in a well-lit environment and will be restricted by the working weather and environment. The power density of flexible thermoelectric devices is low, and it is still difficult to drive common wearable devices. ...
