Abstract

The invention provides polyamide6-graphene quantum dot / carbon nanotube anti-static fiber and preparation. According to the method, the molecular template effect of graphene quantum dots is utilized for being compounded with a carbon nanotube to form a self-assembled three-dimensional network structure first and then combined with a PA6 knitting state structure to form a dislocation effect to construct a conductive path, conductivity is improved on the condition of not losing a mechanical property of PA6 fiber, and meanwhile conductivity and the mechanical property of the PA fiber are promoted. Moreover, by means of compounding of the graphene quantum dots and the carbon nano tube and the self-assembled three-dimensional network structure, electronic transmission efficiency in the carbon nano tube is improved, a small quantity of GQD / CNT is added, conductivity of the fiber can be improved, and transparency is improved at the same time, which is beneficial for treatment technologies like dyeing in the fiber preparing process. By means of the traditional mature PA6 melt spinning technology, the high-strength and high-conductivity PA6-GQD / CNT composite fiber with tensile strength being 0.52-0.81 GPa and line resistance being magnitude 106 is prepared and can be applied to anti-static clothes, needle-punched carpet, filter felt, industrial non-woven fabric, medical supplies and the like.

Description

technical field [0001] The invention belongs to the technical field of composite fibers, and relates to a polyamide 6-graphene quantum dot / carbon nanotube antistatic fiber and its preparation. Background technique [0002] Static electricity can be generated when any two objects of different materials are in contact and then separated. The static charge is not terrible. The static electricity on the human body can sometimes accumulate to tens of thousands of volts. The terrible thing is that the static electricity is released unevenly and violently, which can easily cause circuit breakdown, fire, information interference and other vicious events. Therefore, the prevention of static electricity is very important. important. Anti-static textiles are commonly used in daily life to remove harmful static electricity, and anti-static fabrics are mainly woven with anti-static fibers. Antistatic fibers generally use conductive fibers and antistatic fibers. The antistatic effect o...
