摘要

Carbohydrates have gained much interest in recent years in the research of coatings, as they represent a green and renewable alternative to overcome toxic or environmentally hazardous chemicals. ß-Cyclodextrin derivates are especially interesting in the context of corrosion-resistant coatings, since the inherent nonpolar cavity opens up possibilities to incorporate corrosion inhibitors. In this work a resin based on ß-cyclodextrin, a carbohydrate that can be acquired via enzymatic means from renewable resources and vinyl n-octanoate, a nontoxic vinyl ester, was synthesized. The resin containing ß-Cyclodextrin cavities were then loaded with a corrosion inhibitor and subsequently crosslinked with diisocyanate groups. The resulting coating exhibits excellent adhesion and flexibility in addition to good anticorrosion properties, with the ability to release a corrosion inhibitor from the cyclodextrin cavity. The network formation was verified via dynamic mechanical thermal analysis, while coating properties were investigated by means of application tests and Scanning Kelvin Probe (SKP) measurements. A proof of concept of inclusion-complex formation was carried out on a model system as well as on a typical corrosion inhibitor by monitoring via UV-VIS spectroscopy.
