Effects of Activated Time on Structural Properties of Plated Plant Fiber Nonwoven Sheets

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.

Fabrication of microstructured electrodes via electroless metal deposition onto polydopamine‐coated polystyrene substrates and thermal shrinking

“…This could be attributed to poor adhesion between the film and the substrate and residual stress in the film that arises from a mismatch in the thermal expansion coefficient of the polymer and the copper film, which increases as the thickness of the film increases. [ 37 ] With these observations, the spallation limit of the copper films deposited using electroless plating onto PDA‐PS substrates was established to be ∼160 nm. Given their stability, films made at 40 and 50 mM CuCl 2 were structured via thermal shrinking of the PS substrate at 160 °C.…”
