Abstract
In this work, the effects of activated time on the structural properties of plated plant fiber nonwoven sheet were investigated systematically using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Results showed that there existed a saturated adsorption state on the surface of sheet in the PdCl2 solution. The adsorbed rate and saturated adsorption capacity increased with the increase of PdCl2 concentration. As a result, the deposited quantity and crystallization characteristics of plated nonwoven sheets were firstly enhanced and then unchanged with increase of activated time. The Pd-adsorbed capacity reached saturation point when the activated time was 16[Formula: see text]min. The maximum plated quantity was 0.02 and 0.028[Formula: see text]g/cm2 when the concentration of activating solution was 0.015 and 0.15[Formula: see text]g/L on the surface of sheet.
