“…For example, Vargo et al [680] have region-specifically deposited polycations including polyaniline and polypyrrole onto a H 2 /CH 3 OH plasma-patterned FEP surface. These authors have also demonstrated the possibility for fabrication of both homogeneous and patterned conducting polyaniline multilayer structures with reasonable electrical conductivities.…”

“…[17,18] Charge overcompensation by adsorbing polyelectrolytes, which is often observed when the adsorbing polyelectrolyte molecules possess a higher density of charge than the substrate, has the potential to greatly amplify the electrostatic potential and charge density of weakly-charged surfaces. [20] Cationic polyelectrolytes, such as polyethylenimine (PEI), readily adsorb to negatively charged surfaces.

In this paper, we describe the surface modification of porous polyethylene by the adsorption of polyelectrolyte mutilayers on plasma-activated polyethylene surfaces. We use the migration rates of deionized water as an effective alternative to contact angle measurements in order to probe the interfacial energy of the modified surface. The newly acquired surface properties that result from the surface modification are monitored with respect to several key chemical and environmental variables. These variables were chosen so that they will reflect some of the common handling procedures in a laboratory or health care environments, such as exposure to solvents of different pH and polarities, and fluctuations of ambient temperature over an extended period, i.e., "shelf-life" duration. The stability of these surface properties of the modified membranes is a fundamental requirement for their potential use in a variety of applications involving lateral flow and binding media for bio-assays. In this paper, we show that a membrane modified by a polyelectrolyte monolayer is more stable than a membrane that has undergone plasma activation alone, while a membrane modified by a polyelectrolyte bilayer exhibits retention of the enhanced surface hydrophilic properties under various conditions and over a long period of time.

“…1(d)], which leads to a durable and chemically well-defined modification of polymer materials. [33][34][35] A multiple anchorage of the functional molecule to the solid surface by its charged groups is necessary to prevent the detachment of the molecule during the contact with liquids. In this approach, low pressure plasma is applied to obtain, e.g., positively charged moieties after contact with an aqueous medium that allow adsorbing oppositely charged polyelectrolytes.…”

A survey and comparison of several low pressure plasma‐based approaches to fluorocarbon polymer surface modification is reported including “simple” plasma treatment, “grafting to” and “grafting from” plasma activated surfaces, plasma immobilization of predeposited molecules and the adsorption of charged macromolecules on plasma activated surfaces. Examples of each method are discussed in detail based on results from surface analytical experiments using X‐ray photoelectron spectroscopy, ellipsometry, contact angle goniometry, and electrokinetic measurements. All reported examples refer to one and the same experimental setup. This makes the different approaches comparable and helps to exploit a wide range of plasma‐based techniques for a particular goal and a given apparatus. © 2006 Wiley Periodicals, Inc.
