Zisman plot adhesion

A Zisman plot of a wood adhesive with varying concentrations of aqueous acetic acid is shown in Figure 13.3. Comparing the data obtained with the acetic acid solutions to the data obtained with the solutions of the dissolved wood-related substances, considerable discrepancies between the apparent critical surface tension arrived at with the mixed solutions compared with the critical surface tension arrived at with the pure probe liquid have been observed (not shown in Figure 13.3) (4).

William Zisman was the recipient of numerous awards for his great scientific achievements. The Zisman plot is still widely used in practical applications related to wetting and adhesion phenomena. An account of his research achievements is summarized by Shafrin (1987).

In a further study of Pseudomonas NCMB 2021, Fletcher and Loeb (34) compared attachment to a variety of low energy surfaces. Their clata, together with data from Zisman (2. 35). Metsik (36) and Mittal (13) is plotted in Figure 4. This curve is very sTmi-lar to curves relating c or Wg to adhesive strength for plastics (Dyckerhoff and Sell, ) and metals (Kitazaki and Hata, 1J[) The... 

Two approaches-tools for studying wetting phenomena presented are the Zisman s plot and associated concept of the critical surface tension and the use of interfacial theories. The latter approach may be more complex but provides more information especially when combined with the Young equation for the contact angle. The work of adhesion and the characterization/profile of the solid surface can be obtained as well as ideas about what contaminants...
