Investigation of Adhesion Properties of Polymer Materials by Atomic Force Microscopy and Zeta Potential Measurements

Force measurements with the atomic force microscope: Technique, interpretation and applications

“…glass, silica, and silicon nitride [15,16,187,[427][428][429][430][431][432][433][434]; gold [327,429,435,436]; copper and nickel [437]; zinc and lead sulphide [171,172,438]; titanium oxide [169,339,340]; zirconia [165,166,410]; iron oxide [439]; tungsten [175]; cobalt [175]; and alumina [16,[439][440][441][442]. Different polymers [177,189,[443][444][445][446][447], Langmuir-Blodgett and other thin organic layers [126,329,411,448,449] have been analyzed. In recent years special interest in biologically relevant surfaces materials evolved.…”

Extended Electrokinetic Characterization of Flat Solid Surfaces

“…[9] and [12] that the streaming current depends on the streaming channel dimensions for a given solution and pressure difference. The streaming potential in this case is a function of the total specific electrical conductivity of the channel.…”

“…The streaming potential in this case is a function of the total specific electrical conductivity of the channel. Equation [12] is frequently used in a simplified form neglecting 2K /h, which is justified for large values of h. The ratio of streaming potential and streaming current results in the electrical resistance R (or its inverse the conductance C) of the channel according to Ohm's law:…”

“…A key result concerns the phenomenon of the preferential adsorption of electrolyte cations or anions onto indifferent surface sites of polymer surfaces (11)(12)(13). Preferential ion adsorption was found to be an important surface charge formation process for the vast majority of polymer materials.…”

Direct Measurement of Interaction Forces between Surfaces in Liquids Using Atomic Force Microscopy

“…The metals and their compounds that have been used include gold (Biggs et al, 1994), alumina (Larson et al, 1997), titania (Larson et al, 1995), zirconia (Biggs, 1995), zinc and lead sulphide (Toikka et al, 1997), iron oxide (Sander et al, 2004), tungsten (Andersson and Bergstrom, 2002) and cobalt (Andersson and Bergstrom, 2002). The forces between polymer particles have also been measured using polystyrene (Li et al, 1993), poly(etheretherketone) (Weidenhammer and Jacobasch, 1996) and Tef lon Fig. 4 Forces between carboxyl latex particles in aqueous KCl solutions at pH4.…”
