Problems solved by technology

The conductive fiber generally includes flexible metal wire, metal-coated wire, carbon material conductive fiber, etc., because the metal conductive wire is not resistant to oxidation, has a short service life, strong metal rigidity, poor flexibility, and will scratch the screen; carbon material conductive fiber Such as carbon black composite fiber or carbon fiber, the fiber fineness is large, the rigidity is too strong, etc., so that the use experience of the capacitive writing brush based on the traditional conductive fiber is quite different from the traditional writing brush, and it may scratch the screen of the mobile phone or computer
[0003] It can be seen that in the prior art, the conductive fibers used in the field of touch devices generally have problems such as poor corrosion resistance, high hardness, and easy to scratch the screen, which limits the further application of conductive fibers and is not conducive to the widespread application of such products

Embodiment 1

[0056] The specific preparation method of the capacitor brush is as follows:

[0057] 1) Take a hard hair brush, open it in warm water for 20 minutes, remove the glue seal on the surface of the hair, rinse the brush with distilled water, and remove excess water with absorbent paper;

[0058] 2) A graphene oxide solution with a concentration of 0.4 wt% was prepared with distilled water, and ultrasonically treated for 0.5 h. Immerse the entire part of the brush in the graphene oxide solution, and after the part of the pen is completely absorbed by the graphene solution, take it out and let it stand for 10 minutes, then squeeze out the excess graphene solution and dry it at 25-35°C.

[0059] 3) Prepare a 2wt% L-ascorbic acid solution in hot water at 90° C., keep the temperature, and soak the completely dried pen in the solution for 5 hours. After finishing, rinse the brush to remove excess graphene and other impurities, and dry to get a capacitor brush with conductive brush. The...

Abstract

The invention provides a conductive fiber for a pen, a preparation method of the conductive fiber, a capacitive pen and a touch device. The conductive fiber for the pen comprises a fiber matrix for the pen; a graphene material with micron-sized thickness is attached to the surface of the fiber matrix. The preparation method comprises the steps of dipping the fiber matrix into a graphene material water solution, after that, taking out for standing, and then air-drying or drying; dipping the fiber matrix treated through the above steps into an enhancer water solution, and taking out for rinsingand air-drying or drying. The conductive fiber provided by the embodiment of the invention utilizes electrical conductivity of carbon nanomaterials so as to be well applied to the touch device, is particularly suitable for being applied to the capacitive pen, and is combined with a traditional Chinese writing brush so as to carry out DIY improvement on the traditional Chinese writing brush for realizing the application of the traditional Chinese writing brush on the touch device, so that the problems of poor use experience and short service life of a capacitive Chinese writing brush prepared by other conductive fibers are solved.

Description

technical field [0001] The invention relates to the field of fiber processing, preparation and modification, in particular to a conductive fiber and a preparation method thereof, a capacitive pen and a touch device. Background technique [0002] With the development of electronic technology, especially the popularity of mobile phones and tablet computers, people have fewer and fewer opportunities to write. Brush painting and calligraphy are the classic national quintessence of our country, which greatly enrich people's spiritual life. Art creation is a step-by-step practice process. Using software to practice writing and calligraphy on electronic media such as mobile phones and tablet computers can not only reduce the consumption of paper resources, but also facilitate people to practice art creation anytime, anywhere. Electronic art It is also gradually recognized by the public. However, currently on the market, the capacitive pens matching the existing touch devices are ...
