Abstract

The invention relates to a preparation method of a multifunctional conducting fabric based on a photocuring technology. The method comprises the following steps of (1) preparing graphene / titanium dioxide water dispersion liquid; (2) preparing a waterborne photocuring multifunctional fabric sorting agent; (3) sorting the sorting liquid onto the fabric; performing drying and ultraviolet light curing. After the process, a multifunctional sorting layer can be formed on the surface of the fabric, so that the fabric has good conductivity, antibacterial performance, uvioresistant performance, self cleaning performance and mechanical property. The photocuring technology is used for bonding the graphene onto the surface of the fabric; the process is simple; the durability is high; in addition, the conducting layer has the excellent toughness and intensity; the combination firmness with the base cloth is high; the original hand feeling cannot be influenced; the method belongs to a green energy-saving simple convenient and efficient conducting fabric preparation method.

Description

Technical field [0001] The invention relates to the field of preparation of conductive fabrics, in particular to a preparation method of multifunctional conductive fabrics based on light curing technology. Background technique [0002] With the development of modern technology and the continuous improvement of people’s living standards, high-tech electronic products have penetrated into all aspects of people’s lives, and most electronic products will radiate electromagnetic waves to the surrounding to varying degrees during use. Electromagnetic radiation is harmful to people. The impact of physical health is increasingly evident, so it is imperative to develop efficient anti-electromagnetic radiation fabrics. [0003] Anti-electromagnetic radiation fabrics can be divided into two types: conductive and magnetic. Conductive fabrics generate induced current when subjected to external electromagnetic waves. After that, the induced current generates a magnetic field opposite to the exte...
