一般描述

聚(4-苯乙烯磺酸钠)(PSS)是一种强阴离子聚电解质,在其主链上具有许多负电荷。在这种电解质中,离子电荷在很大程度上与pH条件无关。 PSS沉积物可进行层层组装。静电吸引作用可交替吸附聚阳离子和聚阴离子,以形成聚电解质多层(PEM)。 由于逐层组装,与原始石墨氧化物相比,PSS石墨氧化物表现出较高的双电层电容性能。 纳米颗粒上的PSS涂层可抑制团聚的形成。

In this article, we report a simple approach for selectively sensing Fe2+ ions using CTAB-stabilized Au-Ag nanorods (CTAB-Au-Ag NRs) in the presence of poly(sodium 4-styrenesulfonate) (PSS). The prepared CTAB-Au-Ag NRs exhibit an intense longitudinal surface plasmon resonance absorption (>10(9) M(-1)

We propose a new material for high power and high density supercapacitors with excellent cycle stability. Graphite oxide (PSS-GO) intercalated with poly(sodium 4-styrensulfonate) showed high performance of electric double layer capacitance (EDLC) compared to that of the pristine graphite oxide.

Poly(sodium 4-styrenesulfonate) (PSS)/poly(diallyldimethylammonium chloride) (PDADMAC) multilayers were treated with 1-5 M NaCl solutions, resulting in continuous changes in the physicochemical properties of the multilayers. Significant mass loss was observed when the salt concentration was higher than 2 M and reached

Polyelectrolyte multilayer (PEM) film can modify the surface properties of materials to improve cellular responses. In this study poly(diallyldimethylammonium chloride) (PDADMAC), poly(sodium 4-styrene sulfonate) (PSS) and poly(4-styrenesulfonic acid-co-maleic acid) sodium salt (PSS-co-MA) were assembled into PEM {(PDADMAC/PSS)(4)/PDADMAC+PSS-co-MA} film on glass
