Variability in surface polarity of wood by means of AFM adhesion force mapping

Characterisation of the Interfacial Adhesion of the Different Components in Wood–Plastic Composites with AFM

“…To further demonstrate the versatility of the AFM, Meincken [62] determined the surface roughness and surface polarity of fibres, parenchyma cells and vessel elements of four hardwoods commonly used for pulping and observed a clear distinction between the cell types and species for the surface roughness and polarity. Frybort et al [28] recently utilised the AFM to study the adhesion force between AFM tips and freshly cut wood surfaces. They found clear differences in polarity between freshly cut cell walls and inner cell surfaces at the microstructural level.…”

Wettability of eutectic NaLiCO3 salt on magnesium oxide substrates at 778 K

“…To further investigate this effect, AFM analyses on the MgO substrates were carried out by using a Nanoscope III AFM with functionalised silica tips from Mikromasch (USA). The measurements were done mainly on the adhesion force and the principle of the measurements has been described elsewhere in the literatures [22] [23]. Briefly, an AFM measures the cantilever deflection of the tip displacement due to its interaction with the substrate.…”

Surface Roughness and Wettability Variation: The effect of Cutting Distance during Milling of Pinus Radiata Wood

“…Hansson et al (2011) indicate that surface roughness failed to correctly predict the contact angle on a heterogeneous surface with chemical or topological heterogeneities covered by the droplet. Frybort et al (2014) explain that variability in wettability of a surface is largely determined by surface chemistry, besides other factors such made between the wear of a cutting tool and the wettability of a machined surface. It is not reliable to explain the wettability of machined surfaces considering only the surface roughness on a heterogeneous surface such as wood.…”
