“…z-Potential measurements: z-potential time dependence As already shown, 31 time-dependent z-potential measurements can be used to estimate the water up-take behavior of solid (polymeric) materials (synthetic 37 as well as natural 19 ), which is in good agreement with conventional water absorption measurements performed for differently modified flax fibers. ¶ In the present case one can see that all investigated natural fibers display a different z-potential decay with time.…”

“…In this test, a ball bearing is mechanically forced under the uncoated side of the panel to create a cup on the coated surface. A reverse correlation between the hardness and cupping test was previously reported 28. However, in this study, because of the increased adhesion with the TEOS oligomer, there was no relation between the hardness and cupping test.…”

An unsaturated polyester, based on maleic anhydride, 1,6-hexanediol, and trimethylol propane, was formulated with tetraethylorthosilicate (TEOS) oligomers and a coupling agent to prepare inorganic/organic hybrid films. TEOS oligomers were prepared through the hydrolysis and condensation of TEOS with water, and 3-(triethoxysilyl)propylisocyanate was used as the coupling agent between the organic and inorganic phases. The hybrid materials were cured by moisture via sol-gel chemistry and by the UV curing of unsaturated polyesters. To compare the properties of the moisture-cured inorganic/organic hybrid films, a conventional 2K polyurethane system was also prepared. The tensile, adhesion, abrasion, and fracture toughness properties were investigated as functions of the coupling agent and relative amount of UV cure versus thermal cure. Although no difference could be observed in the tensile properties, the abrasion resistance, fracture toughness, and adhesion were enhanced by the incorporation of TEOS oligomers into polyurethane films. Also, the abrasion resistance, fracture toughness, and tensile properties were increased with both moisture and UV exposure.

“…In particular, functionalities such as carbonyl groups on the polymer surface play an important role during adhesion to steel [30]. Thus oxygen plasma treatment of conventional poly(butylacrylate) polymer surfaces introduces additional carbonyl groups [8,31], which readily coordinate to steel surfaces forming iron carbonates and carbonites [29]. Similarly in the present study, both oxygen and carbon dioxide plasma post treatments of butylacrylate pulsed plasma polymer film lead to an improvement in peel adhesion strength.…”
