Abstract:

In order to prepare a functional composite polyester fabric, oxygen plasma-modified treatment and hot pressing processing were firstly adopted to increase the wettability of the polyester(PET), then the silver nanowires(AgNWs) were dispersed into anhydrous ethanol and the PET fabric was treated with the AgNWs ethanol colloid by a dip-drying process. The AgNWs/PET fabrics were treated by hot pressing process to improve the adsorption fastness of AgNWs. The influence of different concentrations of the colloid on the properties of AgNWs/PET was investigated. With the concentration of the colloid increases from 1 mg/mL to 4 mg/mL, the square resistance of the AgNWs/PET reduces from 25.38 Ω/? to 2.51 Ω/?, but the washing resistance is poor. The electrical conductivity of the AgNWs/ PET which was modified by oxygen plasma is improved after hot-pressing. In addition, after 50 times of washing, the square resistance is increased only by 24.89% , from 0.67 Ω/? to 0.83Ω/?, but the washing resistance is greatly improved.

Key words: silver nanowires, polyester fabric, plasma treatment technology, hot pressing process, electrical conductivity, washing resistance
