“…Soils bind through a combination of Lifshitz-van der Waals, ionic and electrostatic forces (Moeller and Nirschl, 2017). In dry conditions Lifshitz-van der Waals tend to dominate (Kumar et al, 2013) but when immersed in aqueous solution, electrostatic forces, influenced by factors such as pH and electrolyte concentration, play a larger role (Israelachvilli, 1998). Prochaska et al (2007) reported that cationic starches had a stronger binding potential to stainless steel than natural starch, and attributed this to differences in ionic interactions with the steel surface which, when submerged in water, acquire a negative charge.…”

The role of detergent formulation on the cleaning of a complex carbohydrate-fat food soil from stainless steel surfaces was studied using a modified version of the millimanipulation device described by Ali et al. (2015b) which allowed the force required to scrape the soil from the surface to be measured as the soil is immersed, in situ and in real time. This allowed the influence of temperature, solution chemistry and time on the mechanical forces (rheology) and removal behaviour of the soil to be studied-in effect quantifying the relationships in Sinner's cleaning circle. The soil simulated a burnt-on baked-on deposit and featured regular cracking in the 300 m thick layer. The removal force decreased noticeably on hydration: the cleaning mechanism was then determined by the agents present. At 20C, below the temperature at which the fat phase was mobile, removal was characterised by cohesive failure except in the presence of the cationic surfactant CTAB, which promoted adhesive failure and fast decay in removal force. At 50C, when the fat was mobile, a transition between cohesive and adhesive failure was observed at pH 7 which was inhibited at higher pH. Adhesive failure and fast decay in removal force was observed at higher pH and 50C in the presence of the anionic and non-ionic surfactants, SDBS and TX-100, respectively.

“…A validation of the Rabinovich model for predicting adhesion forces between alumina substrates with defined nanoscale roughness is given by Laitinen et al 35 They showed that the estimated adhesion forces using the Rabinovich model correspond well to experimental data even for technical rough surfaces. Kumar et al 11 investigated adhesion forces between silica microspheres and different rough surfaces. Data could be well described by the Rabinovich approach.…”

The adhesion of polyamide 6 (PA6) and polyethylene (PE) toward an aluminum alloy (Al-A) and a dual phase steel (DPS) is studied by contact angle (CA) measurements and atomic force microscopy (AFM). With the combination of the two methods the adhesion properties on a macro- and (sub)microscopic scale can be determined in a nondestructive way. The work of adhesion per area (Wad) of the studied metal/polymer hybrids qualitatively scales the same on both length scales, that is, Al-A/PA6 > DPS/PA6 > Al-A/PE, DPS/PE. The polymer dominates the adhesion. The lower adhesion for PE toward the metal surfaces is explained by dominating van der Waals attraction forces, whereas adhesion for PA6 can also be attributed to attractive polar forces such as hydrogen bonding. For metal/PA6, Wad on a macro- and microscopic length scale is similar. For metal/PE, a discrepancy is measured with lower adhesion values on the microscopic scale than on the macroscopic scale.

“…Then it needed to conglutinate abrasive particles on the tips of AFM to perform measurements. But due to difficulty in manipulation, conglutinated particles must have diameter bigger than 1 μm [12], which was different from size of abrasive particles used in precise polishing. And the tip indented little into material surfaces in AFM measurement due to higher flexibility of cantilever, and it differed from conditions in polishing.…”
