The thermodynamic work of adhesion according to adsorption theory is, without taking into account the primary bonds:
Among specific topics are which fractal parameter contributes most to adhesion, the lattice gas Monte Carlo simulation of capillary forces in atomic force microscopy, new challenges at the nanoscale of the pull-off force and the work of adhesion, molecular mobility and interfacial dynamics in organic nano-electromechanical systems, and the plasma modification of polymer surfaces and their utility in building biomedical microdevices.
Similarly, one might expect the interfacial work of adhesion to be reduced by the reduction in polymer moieties close to the substrate.
The aim of this study was to investigate the effect of surface free energy and the corresponding work of adhesion of biomaterial surfaces on such interactions.
This deceptively simple equation directly relates the thermodynamic work of adhesion to the contact angle.
According to Deryagin and Krotova, the high peel energies were due to dissipation of electrical charges and by comparing the system to a capacitor, the work of adhesion corresponded to the energy necessary to separate the two charged plates as predicted by the Paschen gas discharge curve.
In this article, we used the work of adhesion of the red blood cells as a parameter for characterizing biomaterials versus cell adhesion.
The contact angle data can be used to evaluate the work of adhesion between PVDF, PMMA, and the substrate.
interfacial free energy as minimal (tends to zero), work of adhesion as maximal (optimal) and coefficient of wetting as a positive value (14).
Important adhesion parameters at the interface include the work of adhesion, the interfacial free energy, and the coefficient of wetting (7).
The interfacial tension and work of adhesion between TPU and PA1212 are determined with harmonic-mean equation of Wu [16, 17].
