Anticipating paint cracking: The application of fracture mechanics to the study of paint weathering 总被引:1,自引:0,他引:1
Mark E. Nichols 《Journal of Coatings Technology》2002,74(924):39-46
The relationships between the fracture energy (Gc), film thickness, stress level, and weathering time were investigated for a number of automotive clearcoats. As weathering
progressed, most clearcoats embrittled due to the combined effects of photooxidation, hydrolysis, and other degradation mechanisms.
This embrittlement was measured and related to the chemical composition changes that take place in the clearcoat during weathering.
When the fracture energy dropped below the driving energy for cracking, G, brittle cracking occurred. The driving force for
cracking was shown to depend on stress level and film thickness. The importance of fatigue loading was also qualitatively
investigated. These techniques were successfully used to anticipate the long-term weathering behavior of automotive clearcoats.

《Journal of Adhesion Science and Technology》2013,27(12):1635-1654
In order to explore the fundamental mechanism of paint adhesion to polymer substrates the surface of polypropylene- ethylene propylene rubber (PP-EPR) blends was modified by flame or plasma treatments. The changes in surface composition and properties were investigated and discussed in light of the results of simple adhesion tests. The topography and surface properties of the PP-EPR samples were studied by employing various surface sensitive techniques. Additionally, the surface properties of the pre-treated PP-EPR were compared with the model polymers poly(methyl methacrylate) (PMMA) and polycarbonate (PC) displaying a poor and an excellent paint adhesion, respectively. Differential scanning calorimetry (DSC) measurements showed that the miscibility of the polymer substrate with paint components was an essential factor for the understanding of the adhesion mechanism. A general model of paint adhesion to polymer surfaces is proposed, where the degree of interdiffusion of the polymer chains of the substrate and paint in the interphase determines the adhesion strength. 相似文献
