Adhesion and Delamination Mechanisms of Multilayer Organic Field Joint Coatings on Carbon Steel

Adhesion and Delamination Mechanisms of Multilayer Organic Field Joint Coatings on Carbon Steel

Carbon steel pipelines to transport hydrocarbons installed in the sea need to be coated for corrosion protection on the one hand and for insulation to maintain the temperature of the pipe contents on the other hand. At first, this polymer coating is factory applied to the whole length of the pipe, but afterwards cut back (ca. 40 cm) at the ends of each section (12 m) to allow the offshore welding ...

Molecular mixing in bulk heterojunction organic solar cells - nanomorphology vs performance

The photovoltaic behavior of organic bulk heterojunction (BHJ) blends of conjugated (donor) polymers and fullerene (acceptor) derivatives has been subject of many studies in fundamental chemistry and physics since its initial discovery in 1995. From the general understanding at this moment, the nanomorphology of the active layer blend seems to be crucial. The latter is the result of a complex ...

ICON2 PUrePair: Polyurethane foams and elastomers with autonomic repair.

ICON2 PUrePair: Polyurethane foams and elastomers with autonomic repair.

To eliminate the negative effects of the ageing of plastics, a self-healing approach can be used that is triggered by a degradation mechanism, like e.g. cracking. In this way, a repair function is integrated within the material itself and eliminates the need for human intervention and/or repair. This should ultimately lead to several advantages: - A longer lifetime of the product itself - The ...
