Ternary composites of Ag–loaded polypyrrole/carbon nanotube (Ag–PPy/CNT) are prepared using a one–step in situ polymerization. Ag nanoparticles are uniformly decorated on the core–shell PPy/CNT networks. This approach provides a simple, easily accessible strategy for preparing three–dimensional noble metal–conductive polymer–carbon nanotube composites. Electrochemical properties of Ag–loaded composites are evaluated to understand the effect of Ag on the structure and kinetic process of the composite. Results indicate that the composites have good electrochemical reversibility and high specific capacitance. The specific capacitiance of Ag–PPy/CNT composites are enhanced greatly from 206.7 F g–1 of PPy/CNT composites to 528.6 F g–1 at 3 mA cm–2. This demonstrates that combining nano–sized Ag with supercapacitor materials is very effective in promoting electrochemical performance of materials.

A series of nanofiltration membranes with high flux at low operating pressure were prepared by dynamic self-assembly of poly (styrenesulfonic acid sodium salt) (PSS), poly (4-styrenesulfonic acid-co-maleic acid) sodium salt (PSS-co-MA) and poly (allylamine hydrochloride) (PAH) on the modified polyacrylonitrile (PAN) membrane. Fourier transform infrared spectroscopy (FTIR-ATR) testified that the polyelectrolyte could successfully deposit on the surface of the modified polyacrylonitrile ultrafiltration membrane. The effects of substrates, assemble bilayer number and the capping PAH solution concentration, operating pressure and CuCl2 concentration on CuCl2 removal were investigated. The [PAH/PSS] 1 PAH/PSS-co-MA/PAHc NF membrane composed of only 2.5 bi-layers displayed 88.9% CuCl2 rejection and the permeate flux was 25.1 L/ m2.h when the operating pressure was 0.2 MPa. The CuCl2 rejection was still above 86.3% when the operation pressure increased to 0.8 MPa, meanwhile, the permeate flux increased greatly to 85.8 L/ m2.h.
